This parameter enables the RST button or user input to zero the input display
value, causing the display reading to be offset.
Note: For this parameter to operate, the RST button or User Input being used
must be set to  and the Input value must be displayed. If these conditions are
not met, the display will not zero.

UNITS LABEL BACKLIGHT*
The Units Label Kit Accessory contains a sheet of custom unit overlays
which can be installed in to the meter’s bezel display assembly. The backlight
for these custom units is activated by this parameter.

Current Calibration
1. Connect the negative lead of a precision DC current source with an accuracy
of 0.01% or better to the COMM terminal. Leave the positive lead of the DC
current source unconnected.
2. With the display at  , press the PAR button. Unit will display 

3. Press the RST button to select the range to be calibrated.
4. Press the
PAR button. Display reads 
5. With the positive lead of the DC current source unconnected, press PAR.
Display reads  for about 8 seconds.
6. When the display reads the selected range, connect the positive lead of the
DC
current source to the current input and apply full-scale input signal for the
range. (Note: For 200 mA range, apply 100 mA as indicated on the display.)
Press PAR. Display reads  for about 8 seconds.
7. Repeat steps 3 through 6 for each input range to be calibrated. When display
reads , press the PAR button to exit calibration.
Voltage Calibration
1. Connect a precision DC voltage source with an accuracy of 0.01% or better
to the volt input and COMM terminals of the PAXLA. Set the output of the
voltage source to zero.
2. With the display at , press the PAR button. Unit will display .
3. Press the RST button to select the range to be calibrated.
4. Press the PAR button. Display reads .
5. With the voltage source set to zero (or a dead short applied to the input), press
PAR. Display reads  for about 8 seconds.
6. When the display reads the selected range, apply full-scale input signal for
the range. (Note: For 200V range, apply 100V as indicated on the display.)
Press PAR. Display reads  for about 8 seconds.
7. Repeat steps 3 through 6 for each input range to be calibrated. When display
reads , press the PAR button to exit calibration
