14. In the Range box, select PGH Zero .
15. If the displayed value is not 0.0000 V (within 0.001 V), perform the procedure in the next
section; otherwise, click
Quit when you are finished calibrating the analog input circuitry.
Once you have finished this procedure, continue with “Calibrating the Analog Output
Subsystem” on page 169 .
Note:
If you are not satisfied with the analog input calibration, you can load the factory
default settings stored in the EEPROM by clicking Restore in the Factory Settings box.
Calibrating the PGH Zero Setting
PGH Zero is a factory-calibrated setting and, generally, should not need adjustment. However,
if you select
PGH Zero in the Range box and a value other than 0.0000 V is displayed, do the
following to calibrate this setting:
1. In the Range box, select PGH Zero .
2. Physically adjust potentiometer R2 (labelled PGZ) on the DT3016 board until the display
reads 0.0000 V (0.001 V).
Figure 77 shows the location of this potentiometer.
