Output Relays - GE 489 Instruction Manual

7.2 HARDWARE FUNCTIONAL TESTS
0 to 1 mA ANALOG INPUTS:
1. Alter the following setpoints:
S11 ANALOG I/O
S11 ANALOG I/O
S11 ANALOG I/O
Analog output values should be ±0.01 mA on the ammeter. Measured analog input values should be ±10 units. Force
2.
the analog outputs using the following setpoints:
S12 TESTING TEST ANALOG OUTPUT
S12 TESTING TEST ANALOG OUTPUT
Verify the ammeter readings as well as the measured analog input readings. View the measured values in:
