11.1.4.1 Test Procedure
Test 1: Output at Min position
Place the Device Under Test (DUT) in its minimum or “released” condition.
Measure the voltage V1.
Test 2: Output at Min position: forced
Without causing damage, pull the pedal/ handle hard against the minimum
travel end stop. Measure the voltage V1.
Test 3: Output at Max position
Place the DUT in its maximum or “fully depressed” condition.
Measure the voltage V1.
Test 4: Output at Max position: forced
Without causing damage push the pedal/ handle hard against the maximum
travel end stop. Measure the voltage V1.
Test 5: IVS switch Closed Voltage
Place the DUT in its minimum or “released” condition.
Measure the voltage V2.
Test 6: IVS switch Opening Threshold
Place the DUT in its minimum or “released” condition.
Test 7: IVS switch Open Voltage
Place the DUT in its maximum or “fully depressed” condition.
Measure the voltage V2.
Test 8: IVS switch Closing Threshold
Place the DUT in its minimum or “released” condition.
Test 9: track resistance (potentiometer type sensors only)
