Battery Change / Battery Life
When the battery starts weakening, a low battery warning will appear
(BAT LOW).
Battery change (turn off the instrument before changing the battery!):
Open the battery compartment and change the battery (type CR
2430). Make sure that the O-ring remains embedded in the cover.
The battery life is 2000 hours in normal measuring mode.
Ranges / Calibration
The factory setting of the Zero for the ranges
≤
31 bar is at 0 bar abso-
lute. For sealed gauge pressure measurements, activate “ZERO SEt”
at ambient pressure. Instruments with ranges >31 bar are calibrated
in a sealed gauge mode at ambient pressure.
Interface (RS485)
The interface converter K103A (RS232) or K104A (USB) can be
connected at the back of the manometer, allowing the data transfer to
the PC. The corresponding software can be found on our web site.
