Hint:
Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.
Hint:
Performing the intelligent tester's active test allows relay, vsv, actuator and other items to be operated without removing any parts. Performing the active test early in troubleshooting is one way to save time.
The data list can be displayed in the active test.
