Result: PASS/FAIL

Test 2: Change ADC Update Rate

UID: TST.CN0357.ADC_UPDATE_RATE

RBP: P1

Description: Verify that the ADC Update Rate setting changes the sampling frequency.

OS: ANY

Preconditions:
Steps:
  1. Navigate to the ADC Settings section

    • Expected result: The Update Rate combo box is visible with a default value selected

    • Actual result:

  1. Change the Update Rate to each available option (120, 100, 60, 50, 25, 16 Hz)

    • Expected result: Each selection is accepted and the combo box displays the selected value

    • Actual result:

  1. Verify the ADC measurement updates reflect the selected sampling rate

    • Expected result: The Conversion (mV) reading in the System section updates at a rate consistent with the selected frequency

    • Actual result:

Tested OS:

Comments:

Result: PASS/FAIL

Test 3: Feedback Settings Configuration

UID: TST.CN0357.FEEDBACK_SETTINGS

RBP: P1

Description: Verify feedback type switching, RDAC programming in Rheostat mode, and fixed resistor input.

OS: ANY

Preconditions:
Steps:
  1. Navigate to the Feedback Settings section and verify Rheostat mode is the default

    • Expected result: Feedback Type combo shows Rheostat, RDAC Value spinbox and Program Rheostat button are visible

    • Actual result:

  1. Set RDAC Value to 512 and press the Program Rheostat button

    • Expected result: The RDAC value is written to the AD5270 and the Feedback Resistance in the System section updates accordingly

    • Actual result:

  1. Set RDAC Value to 0 and press Program Rheostat, then set to 1023 and press Program Rheostat

    • Expected result: Both boundary values are accepted and written to hardware without errors

    • Actual result:

  1. Switch Feedback Type to Fixed Resistor

    • Expected result: The RDAC Value spinbox and Program Rheostat button are hidden, and the Fixed Resistor spinbox appears

    • Actual result:

  1. Enter a fixed resistor value (e.g. 10000 ohms)

    • Expected result: The Feedback Resistance in the System section updates to the entered value

    • Actual result:

  1. Switch Feedback Type back to Rheostat

    • Expected result: The Fixed Resistor spinbox is hidden and the RDAC Value spinbox and Program Rheostat button reappear

    • Actual result:

Tested OS:

Comments:

Result: PASS/FAIL

Test 4: System Measurements and Data

UID: TST.CN0357.SYSTEM_MEASUREMENTS

RBP: P1

Description: Verify that the System section displays live measurements and computed calibration data.

OS: ANY

Preconditions:
Steps:
  1. Navigate to the System section

    • Expected result: The Measurements column shows Concentration (ppm), Conversion (mV), and Supply Voltage (V). The Data column shows Sensor Sensitivity, Feedback Resistance, ppm/mV, and mV/ppm

    • Actual result:

  1. Observe the Concentration (ppm) display

    • Expected result: A numeric ppm value is displayed and updates periodically

    • Actual result:

  1. Observe the Conversion (mV) display

    • Expected result: The ADC voltage reading is displayed in millivolts and updates periodically

    • Actual result:

  1. Observe the Supply Voltage (V) display

    • Expected result: The ADC supply voltage is displayed in volts

    • Actual result:

  1. Verify Feedback Resistance displays the computed resistance value

    • Expected result: The value matches the current feedback mode configuration (RDAC-derived or fixed)

    • Actual result:

  1. Verify ppm/mV and mV/ppm conversion coefficients are displayed

    • Expected result: Both coefficients show non-zero numeric values consistent with the current sensor sensitivity and feedback resistance

    • Actual result:

Tested OS:

Comments:

Result: PASS/FAIL

Test 5: Change Sensor Sensitivity

UID: TST.CN0357.SENSOR_SENSITIVITY

RBP: P1

Description: Verify that changing the Sensor Sensitivity updates the computed concentration and conversion coefficients.

OS: ANY

Preconditions:
Steps:
  1. Navigate to the System section and note the current Sensor Sensitivity value

    • Expected result: Sensor Sensitivity spinbox shows the default value of 65 nA/ppm
