Valve Tests (710)

Step Test

In this test the mA signal is changed in steps and compared to the

position variable (QV).

To set up the step size for the test from 0.1 mA to 4 mA, rotate the

selection knob to change the mA value.

Figure 55. Step Test

To run the test:

1. Push  to start the test.

• Good test result: the position variable is as expected.

• Marginal test result: the position variable value is found to

be close to the test tolerance.

• Bad test result: the position variable deviation values vary

greater than the tolerance.

2. Select Save to save the test results and upload later to the

ValveTrack software.

Or, select Discard if you do not want to save the test result.

Bump/Partial Test

The Bump/Partial Test is a test of the valve over a smaller portion

of the stroke, or bump the mA value, to find if the valve moves as

expected. This is also done with a Manual Test of the position or

other values.

To set up:

1. Set the start and stop stroke values in % of travel.
