CN0359 Conductivity Measurement System User Guide

Overview

The CN0359 is a complete, highly accurate conductivity measurement system designed for applications involving ionic content measurement of liquids, water quality analysis, industrial quality control, and chemical analysis.

A carefully selected combination of precision signal conditioning components yields an accuracy of better than 0.3% over a conductivity range of 0.1 μS to 10 S (10 MΩ to 0.1 Ω) with no calibration requirements. Automatic detection is provided for either 100 Ω or 1000 Ω platinum (Pt) resistance temperature devices (RTDs), allowing the conductivity measurement to be referenced to 25°C.

The system accommodates 2-wire and 4-wire conductivity cells, and 2-wire, 3-wire, and 4-wire RTDs for improved accuracy and flexibility.

Hardware Connections

The following sections will describe the hardware in more detail.

The CN0359 have 5 connectors:

  • J1 for power supply
  • J2 for RS-485 communication (Rev A) or UART communication (Rev B)
  • J3 for RTD temperature sensor
  • J4 for JTAG/SWD debug
  • J5 for conductivity sensor


EVAL-CN0359-EB1Z Rev. A


EVAL-CN0359-EBZ Rev. B



The following equipment are required to evaluate the CN0359:

  • CN0359 circuit evaluation board
  • EVAL-CFTL-6V-PWRZ 6V DC wall connector (or equivalent)
  • 2-wire and 4-wire conductivity cells
  • 2-wire and 3-wire and 4-wire PT100 and PT1000 RTDs
  • PC with Microsoft Windows 7 (or later OS) and USB 2.0 (or faster USB) port
  • USB to RS-485 converter cable (Rev A) or ADALM-UARTJTAG or similar USB to UART bridge module (Rev B)
The following conductivity cells have been used to test the functionality of the CN0359:
  • TOPAC CS SK10T (2-electrode cell)
  • TOPAC CS SK40T (4-electrode cell)

The following extra equipment are require to reprogram or debug the CN0359:

  • J-link debug cable (or equivalent JTAG/SWD debug cable)
  • 20-pin/10-pin JTAG/SWD adapter (Rev B only)


Conductivity Sensor Connections

The CN0359 supports both 2-electrode and 4-electrode types of conductivity sensors. The conductivity sensor should be connected to J5 of the evaluation board.

Refer to the following table for the pin map of J5:

Pin Number Signal Name Pin Description
Pin 1 I(+) (+) Conductivity Probe Excitation Current Pin
Pin 2 V(+) (+) Conductivity Probe Voltage Sense Pin
Pin 3 V(-) (-) Conductivity Probe Voltage Sense Pin
Pin 4 I(-) (-) Conductivity Probe Excitation Current Pin
Pin 5 GND Ground
The error specification for the CN0359 is +/- 0.3% within the 0.1 μS to 10 S (10 MΩ to 0.1 Ω) conductivity range. If the conductivity of the solution being measured is outside this range, extra error may be introduced.

During conductivity measurement, the excitation current flows into the sensor through the I pins and then translated into a voltage signal by an onboard transimpedance amplifier. This signal, plus the voltage developed across the V pins, are then amplified and then sampled by the microcontroller ADCs.

Refer to following pictures for the proper conductivity sensor connections. Sensor connections are the same for both Rev A and Rev B evaluation boards.

2-Electrode Conductivity Sensor Connection

When using 2-electrode sensors with the CN0359 evaluation board:
  • Pin 1 ⇔ Pin 2 of J5 MUST be shorted.
  • Pin 3 ⇔ Pin 4 of J5 MUST be shorted.

4-Electrode Conductivity Sensor Connection


RTD Connections

The CN0359 supports PT100 and PT1000 RTD sensors connected in either 2-wire, 3-wire, or 4-wire mode; the RTD type and connection mode will be automatically detected by the software. The RTD temperature sensor should be connected to header J3 on the evaluation board.

The J3 pin map is following:

Pin Number Signal Name Pin Description
Pin 1 I(+) (+) RTD Excitation Current Pin
Pin 2 V(+) (+) RTD Voltage Sense Pin
Pin 3 V(-) (-) RTD Voltage Sense Pin
Pin 4 I(-) (-) RTD Excitation Current Pin

During RTD measurement, constant excitation current flows into the RTD through the I pins, and the resulting voltage difference across the V pins is sampled by the microcontroller ADCs.

Refer to the following pictures for the different RTD wire mode connections. RTD connections are the same for both Rev A and Rev B evaluation boards.

In the Rev A evaluation boards, J2 is a terminal block with the following pin map:

Pin Number Signal Name Pin Description
Pin 1 B RS-485 B Signal
Pin 2 GND Ground
Pin 3 A RS-485 A Signal
The CN0359 software is capable of supporting up to 254 boards (with RS-485 addresses from 1 to 254) connected to one RS-485 network. To improve noise performance, the RS-485 terminal resistor (R10) on the Rev A boards is set to 10 kΩ.

If multiple devices will be used on the same RS-485 network, R10 may need to be changed (or removed completely) to comply with the RS-485 standard. For more information about RS-485, refer to: www.analog.com/an-960 or ANSI/TIA/EIA-485 standard

Usage Instructions

The CN0359 is powered from a 6V DC wall connector (EVAL-CFTL-6V-PWRZ) and will run automatically when the supply is plugged in. The conductivity and RTD measurements can be displayed using two interfaces: the onboard LCD screen or the remote network interface (RS-485 for Rev A; UART for Rev B). Both interfaces can also be used simultaneously if desired.

The CN0359 has the following settings that can be programmed by the user:

  • Excitation Voltage
  • Excitation Frequency
  • Track-Hold Setup Time
  • Track-Hold Hold Time
  • Temperature Coefficient
  • Conductivity Cell Constant
  • Baud Rate
  • RS-485 Address (Rev A only)
  • LCD Contrast
Always check the excitation voltage and frequency before connecting the conductivity sensor to the CN0359 evaluation board. Using a setting that is outside the specifications of the sensor can cause damage.


LCD Screen and Encoder User Interface

By default, the LCD screen will display the measurement results of the CN0359. When used with the encoder S1 however, it can instead be used to navigate a menu-based interface to configure the different CN0359 settings listed above.

General Usage Instructions

The text in the menu interface can have one of the three following states:

Normal (dark font with light background) Indicates an available option or value
Reverse (light font with dark background) Indicates the currently selected option or value
Blinking (switches between normal and reverse states) Indicates a value that is currently being edited by the user

To interact with the menu items, the encoder S1 can be turned clockwise or counterclockwise. It has no mechanical stop, and can also be used as a push button. The following details the operation of the encoder:

Control Menu via S1 Equivalent Operation
Turn clockwise when there is no blinking text Move to the next option or value
Turn clockwise while there is blinking text Increase value
Turn counterclockwise when there is no blinking text Go back to previous option or value
Turn counterclockwise while there is blinking text Decrease value
Push button when there is no blinking text Use option or start editing value
Push button while there is blinking text Stop editing value


There are two exceptions to the behavior described above:

Home or Measurement Screen There is no selectable option or value in this screen so turning the encoder will have no effect.
Push the button to enter the main menu interface.
LCD Contrast Setting Screen Turning the encoder clockwise/counterclockwise will increase/decrease LCD contrast, respectively.
Push the button to return to the main menu.


The CN0359 also has a buzzer on the evaluation board. When editing a value, it will provide an audible indication when the maximum or minimum setting has been reached.

CN0359 Start Up and LCD Contrast

The contrast of the LCD screen can be set by the user; however, if the LCD contrast is set improperly, the text may become difficult to read. If needed, the following procedure can be used to “blindly” adjust the LCD contrast:

  1. Power up the CN0359 evaluation board. If the onboard buzzer beeps for 50 ms immediately, the system was able to load the previous settings properly.
  2. Push the encoder button S1 within 3 seconds after powering on.
  3. The onboard buzzer will beep for 100 ms twice, with an short interval of 100 ms in between. This indicates that the interface is now in the LCD contrast setting screen.
  4. Turn the encoder S1 clockwise/counterclockwise to increase/decrease LCD contrast. Adjust it such that the text will appear clearly and sharply.
  5. Push the button S1 to exit the LCD contrast setting screen.
  6. Select the “Return to home” option in the main menu and press the button. The new LCD contrast setting should now be saved.


Buzzer and Alarm

The CN0359 evaluation board has a buzzer U2 on it that produces notification sounds during operation. The buzzer is activated in the following events:

  • Beeps once after connecting power to the board, and beeps again after the home/measurement screen appears.
  • Beeps twice if button is pushed while the splash screen is displayed during power-up. If this occurs, the interface will enter the LCD contrast setting screen.
  • Beeps five times rapidly if an internal error is encountered during start up. When this occurs, all settings will be reset to their default values.
  • Beeps whenever an RTD error is encountered while at the home/measurement screen. Check the RTD connection when this occurs.
  • Beeps whenever a conductivity sensor error is encountered while at the home/measurement screen. Check the sensor connection when this occurs.
  • Beeps when user tries to set a programmable value (e.g., EXC voltage, EXC freq, etc.) outside the acceptable range.


Data Communications Interface

To communicate with the CN0359 from a PC, use a RS-485 to USB converter (or UART to USB bridge, depending on the version of the board) and a terminal emulator such as Putty or Tera Term. Please check the settings of your software before connecting to the board. The output of the terminal program must match the following command formats.
The RS-485 interface for Rev A, and the UART interface for Rev B both use char '\n' LF (Line Feed) as the ending character. This means that the CN0359 will respond to a valid command immediately after receiving char '\n'. Please make sure that char '\n' is the last byte that will be sent to CN0359 in each command string. Some serial port terminal software can automatically add char '\n' to the output stream upon pressing the Return key. For software that cannot append char '\n' automatically, the command string should be sent to the CN0359 in hexadecimal format with 0x0a appended.

The CN0359 software uses char ' ' (i.e., the space character) as a delimiter in the command string.


Rev A: RS-485 Command Usage

Click to display ⇲

Click to hide ⇱

In this user guide, the CN0359 is referred to as the client, and the PC (or any device used to initiate communication) is referred to as the host.

The half-duplex RS-485 interface used in Rev A boards can connect multiple (up to 254) clients in the same network. All clients are kept in receive status while idle, and can only transmit data when given the appropriate command.

Only one device can send data at the a given time in this configuration; otherwise the RS-485 network will encounter signaling conflicts. If multiple hosts exist in your network, please ensure that no such conflicts occur.
The RS-485 address can only be changed through the LCD and encoder user interface. Set the desired address first prior to sending commands to the board.

The following format is used to explain the different RS-485 commands in this user guide:

SYNOPSIS

address command option

DESCRIPTION

The address is the integer value of the RS-485 address, ranging from 1 to 254. The address should always go before the command and the option for proper communication to the corresponding CN0359.

poll - Query CN0359

address poll

The poll command is used to query the CN0359 for its programmed settings and its sensor readings. For example, entering the following will query the CN0359 at address 100 for its settings and its measurements: 

  100 poll

setvolt - Set Excitation Voltage

address setvolt voltage

The setvolt command is used to set the peak voltage of the cell excitation signal, ranging from 0.1 V to 10 V. For example, the following command will set a 2.5 V peak excitation voltage for the CN0359 at address 100: 

  100 setvolt 2.5

setfreq - Set Excitation Frequency

address setfreq frequency

The setfreq command is used to set the frequency of the cell excitation signal, ranging from 10 Hz to 100000 Hz. For example, the following command will set an 85.6 Hz excitation frequency for the CN0359 at address 100: 

  100 setfreq 85.6

setk - Set Cell Constant

address setk K

The setk command is used to input the cell constant of the conductivity sensor used, ranging from 0.01 cm-1 to 100 cm-1. For example, the following command will input a cell constant of 1.268 cm-1 to the CN0359 at address 100: 

  100 setk 1.268

setcof - Set Temperature Coefficient

address setcof coefficient

The setcof command is used to input the temperature coefficient of the test sample, ranging from -10%/°C to 10%/°C. For example, the following command will input a -2.58%/°C temperature coefficient to the CN0359 at address 100: 

  100 setcof -2.58

setstm - Set Track-And-Hold Setup Time

address setstm time

The setstm command is used to set the track-and-hold setup time as a percentage of a half excitation period, ranging from 0% to 80%.

Setup time is measured from the start of a half excitation period to the moment the CN0359 begins tracking the measurement voltages.

For example, the following command will set a 5.8% setup time for the CN0359 at address 100: 

  100 setcof 5.8

If the excitation frequency is 100Hz, then half of the period will be 5 ms. The track-and-hold setup time in this example will therefore be 290 μs.

sethtm - Set Track-And-Hold Hold Time

address sethtm time

The sethtm command is used to set the track-and-hold hold time as a percentage of a half excitation period, ranging from 0% to 10%.

Hold time is measured from the moment the CN0359 stops tracking the measurement voltages to the end of a half excitation period.

For example, the following command will set a 1.5% hold time for the CN0359 at address 100: 

  100 sethtm 1.5

If the excitation frequency is 1 kHz, then half of the period will be 500 μs. The track-and-hold hold time in this example will therefore be 7.5 μs.
