The ERZ2000 has 2 clocks - a long-term clock (hh:mi:ss /hours:minutes:seconds/
DD:MO:YY / day:month:year/) and a short-term clock that can be calibrated. The
short-term clock is used for totalizer integration for effective pressure computers, cal-
ibration on the fly and operating point testing and frequency measurement.
Both clocks have individual clock drift. Over a period of 1.2 million seconds (
KD01 ),
the long-term clock runs 85 seconds ( KD07 ) faster than the short-term clock.
