3. To change the output voltage issue a CAL[n]:NEG5 nn
command. Note that a change of one count of nn from the X value
returned in Step 2 will change the output by
≈ 3 mV.
4. Repeat Step 3 until the measured voltage is within the range from
- 4.997 to -5.003 volts.
-15 C ALIBRATION
1. Connect the DMM to the -15 volt supply and measure the DMM
voltage. If the voltage is within the range from –14.970 to –15.030
volts the calibration is acceptable so proceed to the Saving
Calibration section.
2. Issue a CAL[n]:NEG15? Command.
Note the returned value = X.
3. To change the output voltage issue a CAL[n]:NEG15 nn
command. Note that a change of one count of nn from the X value
returned in Step 2 will change the output by
≈ 30 mV.
4. Repeat Step 3 until the required output voltage is within the range
from –14.970 to –15.030 volts.
S AVING C ALIBRATION
If none of the supplies required adjustment during the calibration procedures,
the Calibration Procedure is complete.
If one or more supplies required adjustment, the new calibration values must
be saved. To save the calibration values, issue the following commands:
CAL[n]:UNLOCK ”6867”
CAL[n]:STORE
CAL[n]:LOCK
This saves the FPDC calibration valves and calibration is now complete.

The FPDC module is quite simple so the steps needed to set it up consist of the
following:
1. Unpack the module checking for any shipment damage as herein
outlined.
2. The FPDC can be installed in any available slot in any chassis.
There may be some established configuration that needs to be
followed but the module can function in any position.
3. Check both the connector on the rear of the module and the
mating connector in the chassis to be sure that there is no residual
debris that may prevent the connectors from mating.
