.
7.
Set the calibrated input to 9.5068 V.
8.
Adjust Pot R46 for 9.5068 V.
9.
Repeat the procedure and verify the adjustments are correct.
10.
Set the precision voltage source to -9.95117 V and check for a reading of -9.95117.

1.
Verify the termination panel is connected to a 50-pin connector of the UDAS unit. Begin with
step 2 if the unit has built-in termination.
2.
Attach a voltage calibrator to channel 0 with all other channels grounded.
3.
Run a program, such as SYSCHECK, to configure the UDAS for a range of ±5 V and gain of 1.
4.
Set calibrated input to 0 V, or short channel 0 to analog ground.
5.
Set SYSCHECK or other program to average 50 readings. Manually or automatically take
readings repeatedly.
6.
Adjust Pot R39 until the software displays 0 V.
7.
Set the calibrated input to 4.5734 V.
8.
Adjust Pot R40 for 4.5734 V.
Note:
On all adjustments, there is likely a range of adjustment resulting in the proper
reading. Determine this range and leave the adjustment in the center of the range.
Note:
These adjustment steps are interactive and may require several iterations.
Note:
If the value you read is more than 0.039 V different from -9.95117, then the
following Alternate Bipolar Calibration must be used.
Note:
On all adjustments there will be a range of adjustment that results in the proper
reading. Determine this range and leave the adjustment in the center of the range.
