3. Verify the ammeter readings as well as the measured analog input readings. For the purposes of testing,
the analog input is fed in from the analog output (see Figure 7–1: SECONDARY INJECTION TEST
SETUP). View the measured values in:

1. Alter the following setpoints:
S12 ANALOG I/O\ANALOG INPUT1\ANALOG INPUT1: 0-1 mA
S12 ANALOG I/O\ANALOG INPUT1\ANALOG INPUT1 MINIMUM: 0
S12 ANALOG I/O\ANALOG INPUT1\ANALOG INPUT1 MAXIMUM: 1000 (repeat for analog inputs 2 to 4)
2. Analog output values should be ±0.01 mA on the ammeter. Measured analog input values should be ±10
units. Force the analog outputs using the following setpoints:
S13 TESTING\TEST ANALOG OUTPUT\FORCE ANALOG OUTPUTS FUNCTION: Enabled
