Calibration Steps
To calibrate the Product, apply the values shown in Table 3 for the correct
Product. If the Product fails to show the correct indication, adjustment is
necessary. Calibration can be done in any pressure unit that can be shown on
the Product display. Pressure units of psi and kPa are shown in Table 3 as
examples. If calibrating in other units, use points that are as close as possible to
those in Table 3.

Serial Point Adjustment
Adjustment of the Product is done electronically with internal software. It is not
necessary to open the Product case. All calibration commands and adjustments
are done through the serial port connection. If the processes in the next sections
do not bring the Product into specification, then it will be necessary to send your
Product to Fluke Calibration for calibration adjustment.
Set Zero
After all connections are made, vent the Product to atmosphere and send this
command:
OFFSET_ADJ?
Note the value that is shown. When the pressure is stable, send:
OFFSET_ADJ N
N is the pressure given from the previous OFFSET_ADJ? command.
Set Span
Send the GAIN_ADJ? command.
Note the value shown. Use the correct pressure standard to input a value equal
to or near the noted value. When pressure is stable, send:
GAIN_ADJ N
