 +  - Double click the AD4130-8 Eval Board icon to open the AD4130-8 Eval Board view window. The demo wizard will be on the left, either as shown in the figure below (Label 1) or already expanded. Expand the wizard by clicking the arrow (Label 2). {{ :resources:eval:user-guides:ad4130-8:softwareprocedures:ad4130_rtd_config_tab.png?600 |}}
 +  - With the wizard expanded, select the RTD button (Label 3). 
 +  - In the Configuration Options tab (Label 4), select 4 Wire for Number of Wires, select your RTD type either PT100 or PT1000 and pick which AVDD voltage you have set on the board either 1.8V or 3.3V. This will configure the AD4130-8 registers to the optimum RTD setup.
 +  - The settings required for the demo are displayed to be viewed prior to writing to the AD4130-8 (Label 5). Click apply (Label 6) to write these settings to the board. 
 +  - The summary is then displayed once the write is complete (Label 1). {{ :resources:eval:user-guides:ad4130-8:softwareprocedures:ad4130_rtd_config_tab_2.png?600 |}}
 +  - From here navigate to the chip view by double-clicking the AD4130-8 chip (Label 2).
 +  - To make further changes to the configuration click on the dark blue block in the chip view (Label 1) or double click the memory map option (Label 2)
 +  - To begin capturing data double click the Analysis button (Label 3). {{  :resources:eval:user-guides:ad4130-8:softwareprocedures:ad4130_8_ace_noise_test_chip_view.png?600  |  }}
 +  - To gather samples, change the Samples Count (Label 1) to the number of samples required, then click the Run Once button (Label 2) to acquire the samples from the ADC. The image below shows an example of the main window after running a RTD demo mode.{{ :resources:eval:user-guides:ad4130-8:softwareprocedures:ad4130_rtd_results_tab.png?600 |}}

 +=== Reading Samples from the ADC ===
 +The evaluation board is set up to use the external 2.044 V in the RTD demo mode(when AVDD is set to 3.3V in Configuration Options tab or it is 1.022V if 1.8V is selected) on-board reference (From the 5.11k ohm precision resistor). To read samples from the ADC, do the following:
 +  - The value in the Refin1(+/−) field on the Configuration tab is set to 2.5 V by default to use the external 2.5 V on-board reference (ADR391). If a different reference is used to the AD4130-8, the Refin1(+/−) field should be updated accordingly (i.e. 2.044 V for AVDD set to 3.3 V and 1.022 V for AVDD set to 1.8 V). (The analysis results are based on the value set in this input field.) 
 +     * Information on the reference choice can be viewed in the [[resources:eval:user-guides:AD4130-8:hardwareguide#reference_options|Reference Options Tab]]
 +  - When selecting Run Once, a batch of samples is read when clicking the button; the batch size is set by the value in the Samples field.
 +       - When selecting Run Continuous, the software performs a continuous capture from the ADC by clicking the Run Once button. Click the Stop Capture button again to stop capturing data.
 +   - Use the navigation tools within each graph to control the cursor, zooming, and panning.
