This menu gives a channel specic summary
of deviations of calibration results.
Note!
This menu is a submenu of CALIBRATION

from several higher-level menu.
6.2.2 Control Menu
In the context of this menu, deviation means
the value, a calibration corrected the zero or
respectively the span calibration value.
"ZeroDev." or "SpanDev." in concentration
units give the correction of the last correspon-
ding calibration.
"ZeroDev. Total" or "SpanDev. Total" in
concentration units give the total (sum of)
corrections of the corresponding calibrations
since the last time, deviations have been reset
( SETUP - CALIBRATION - DEVIATIONS;
6-43)
Example:
A measuring channel shows zero drift of
10 ppm per week. It is calibrated once a
week.
After the 3
rd
zero calibration, DEVIATIONS
shows:
ZeroDev: 10 ppm (=last calibr.)
ZeroDev. total: 30 ppm (=summary of 3
calibrations carried out
within 3 weeks)
