Verification Procedure
Complete the following procedure to verify the AO differential gain accuracy.
Repeat 2 times, once for each channel.
1. Connect the AO channel under test to the DMM as shown in Figure 3.
Repeat 2 times, once for each output terminal configuration.
Repeat 4 times, once for each AO Attenuation.
2. Configure the DMM using the information in Table 16.
Table 16: DMM Configuration
Configuration Value
Function AC Volts (ACV)
Range* 10 V
RMS Mode (SETACV) 3 (SYNC)
AC Bandwidth (ACBAND) 20 Hz
Level Filter (LFILTER) 1 (ON)
*Refer to Table 17 for details about the correlation between AO Gain, DMM Range, and Signal
Amplitude.
