4.4.3 ANALOG REFERENCE CALIBRATION (VXI plug&play DEMO)
During analog reference calibration the external analog reference voltages used to establish full
scale output current and voltage are defined. The factory default calibration of 10V programs full
scale output, however the following procedure allows any d-c value up to 10V to program full
scale, while a voltage proportionately less programs a corresponding decrease in the output.
1. Click the ANALOG REF button on the Calibration Window; the Analog Reference Calibration
Window (Figure 4-4) appears and the status display on the VXI main panel reads INPV .
When the reference voltage is at the desired value, click the PRESS TO ACCEPT button to
accept the value. When the calibration is saved, this analog voltage will be equivalent to full
scale output voltage.
NOTE: The full scale output voltage is determined by the virtual settings in effect. Therefore, if,
e.g., a KLP 75-33 virtual setting is 60-13, a 10V analog reference voltage programs the
voltage to full scale (60V, 13A).

2. The status display reads INPC . Connect the reference voltage used to define full scale out-
put current as described in PAR 3.4 .
3. When the reference voltage is at the desired value, click the PRESS TO ACCEPT button to
accept the value. When the calibration is saved, this voltage value will be equivalent to full
scale output current.
NOTE: The full scale output current is determined by the virtual
settings in effect.
4. The status display will not change. Proceed to PAR. 4.4.4 to exit calibration.
