CORRECTION ZERO AND GAIN ERROR (ZERO-OFFSET AND GAIN-OFFSET) FOR
HANDHELD INSTRUMENT CLINO 2000
Each instrument has, with increasing duration of use, a so-called drift and a ZERO-offset. This “error“ may
be compensated for by a reversal measurement on a CLINO 2000. If the ZERO-offset as well as the linearity
are out of tolerance, it is easy to calibrate the CLINO 2000 ±45° thanks to implemented software guidance
and the calibration aids. The devices with a measuring range of ±10°, ±30° and ±60° have no calibration
aids - only a factory calibration is possible..

The zero-deviation (ZERO-offset) can be If the ZERO-offset as well as the linearity (GAIN-
eliminated, or compensated for with a reversal error) are out of tolerance, only the ZERO-offset
measurement. can be compensated by a reversal measure-
ment. The GAIN-error will remain.

The GAIN-error will remain. This error can be After the calibration, the device is ready for
