4. Click the PRESS TO ACCEPT button to accept the value. The status display reads CMAX .
Click the “+” button to increase and the “–“ to decrease the output current until the DVM
reads as close as possible to maximum rated current (Calculate current as follows:
I (Amperes) = DVM reading (Volts) / Shunt Resistance (Ohms).
5. Click the PRESS TO ACCEPT button to accept the value. The status display reads OUTC .
Connect to DVM (+) to Analog I/O Port J2, pin 7 and DVM (–) to pin 13. Click the “+” button
to increase and the “–“ to decrease the output current until the DVM reads as close as pos-
sible to 10V.
6. Click the PRESS TO ACCEPT button to accept the value. The status display will not change.
Click the ANALOG REF button on the calibration window to proceed to external calibration
(see PAR. 4.4.3).
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.
NOTE: The full scale programming voltage has a 1:1 correspondence with the external read-
back; i.e., 10V full scale programming voltage results in a 10V full scale readback. If
the full scale programming voltage is changed to a value other than 10V, the full scale
readback voltage is changed accordingly.
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 but-
ton 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 vir-
tual settings in effect.
