measurement results to the appropriate test limits shown in the table.
Analog Output Adjustment
This adjustment procedure sets a zero adjustment and a gain adjustment
constant for each DAC output. You must perform all the adjustments on one
analog output channel before adjusting the other analog output channel.
1 Install the module in slot 100. Select the first analog output channel (104).
2 Connect an external DMM to the output terminals.
3 Set the analog output to 00.000 V.
4 Press

again to begin the
adjustment procedure.
5 Use the knob, and to set the number in the display to the measured
output value and press
to complete the adjustment.
6 Set the analog output to 10.000 V.
7 Press
