Internal Lithium Backup Battery
A lithium battery maintains the memory contents and
Setup settings. The normal service life for the lithium
battery is 3 to 5 years.
You cannot access the lithium battery. Return the
calibrator to an authorized Beta service center.
When the lithium battery is 3 years old, replace it at
the next calibration interval as a preventive
maintenance procedure.
Cleaning the Calibrator
Clean the calibrator and pressure modules with a
soft cloth dampened with water or water and mild
soap.
Caution
To avoid damaging the plastic lens and
case, do not use solvents or abrasive
cleansers.
Calibration Data
The date the calibrator was last calibrated shows on
the calibration sticker. The date the calibrator was
last adjusted is shown on the last screen in the
Setup mode. The CAL. STATUS number on the
sticker should always match the Calibration Status
number in the calibration
s screen. Calibration of
the MasterCAL is to be done by qualified personnel.
In Case of Difficulty

the calibrator serviced.
If the display is blank or unreadable, but the beeper
works when you turn the calibrator on, make sure
the contrast is not maladjusted. Press the
u and
d keys to adjust the contrast.
