4. Store this value by pressing the ‘MENU’ button and then advance to
“OUTPT2”. Use the ‘MIN’ and ‘MAX’ buttons to enter the desired output
for the display value in step 3. For example, enter “20.0000” for
calibrated current or “10.0000” for calibrated voltage.
5. Press the ‘MENU’ button to store. Press the ‘RESET’ button two times
to return to run mode and check calibration points, unless your analog
output board is newly installed; in this case, follow Section 12.5.
12.5 BOARD INSTALLATION; ENTERING THE TRIM DATA
To precisely calibrate your analog output board with your meter, each analog
output board has been supplied with voltage and current zero trim values
printed on the board. “CAL VZ” is for the voltage output and “CALmAZ” is for
the current output.
Similarly, the fine trim for output gain is “CAL VS” for the voltage output and
“CALmAS” for the current output.
These 4 data points are obtained from the factory calibration of each analog
output board and are inscribed on the edge of each board, as shown in
Figure 12-1.
