Preliminary Operations

Review and become familiar with the whole procedure before beginning a
calibration process.
Allow at least one hour for the calibrator to thermally stabilize after switching
on and before calibration.
Before starting a calibration procedure:
Carry out a leak test.
If necessary and as a separate procedure from the calibration procedure:
Notes on calibration
The pressure standard outlet port and the indicator inlet port must be at the
same level.
On gauge measurements, applying positive pressure to the reference port
produces a negative pressure.
Set the calibrator units of pressure to one of the following recommended units
of pressure measurement:
2
Pa, hPa, kPa, MPa, bar, mbar, torr, kgf/cm .
Calibration Security
GE Druck strongly advise protection of the set-up menus in this equipment.
Unauthorised access to the calibration menu can result in degraded
performance and inaccuracy. The factory set PIN is: 4321 press MENU OK. The
code can be changed to another code of 4 digits; entering 0000 disables this
security facility.
Note; Refer to the user manual to change PIN codes.
General
1. Carry out a leak check, refer to the User Manual.
2. Connect the instrument and carry out a calibration check.
3. If necessary, carry out a calibration adjustment.
4. After completing the calibration adjustments, adjust the calibration
standard to atmospheric pressure.
5. Carry out a calibration check to verify this procedure.
6. Disconnect calibration standard from the instrument.
