The 469 specification for analog input and analog output accuracy is ±1% of full scale.
Perform the steps below to verify accuracy. Verify the Analog Input +24 V DC with a
voltmeter.

value for Analog Inputs 2 to 4)
Analog output values should be ±0.2 mA on the ammeter. Measured analog input
values should be ±10 units.
 Force the analog outputs using the following settings:

S13 TESTING TEST ANALOG OUTPUT
(enter desired value in percent; repeat for Analog Outputs 2 through 4)
 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 on page 7–2).
