Editing zero point drift values

Procedure
1. Main menu > "3. Maintenance & Diagnostics" > "6. Drift values" > "1. Zero point drift"
This menu includes the following information on each measuring range which makes it
easier for you to detect/monitor the zero point drift:
– Previous zero gas calibrations
– Previous deviations
2. Set warning limit for the total deviation of the measuring ranges.
The total deviation is calculated for a specific number of zero calibrations. The
corresponding deviation is added following each zero calibration. A warning is output if
the value of the total deviation exceeds the warning limit.
– "Warning limit in % of MR" parameter field.
– Authorize access with Standard PIN, if necessary.
– Enter the limit in %.
3. Reset the zero point drift
– Enter number of calibrations after which the zero point drift is reset.
– Reset the zero point deviation values for all measurement ranges:
Operating with the Local User Interface
Operating Manual, 06/2017, A5E31930478-05
The deviations of the zero calibration are added up to the entered number. The total
deviation is then reset to 0, and counting of the calibrations begins again.
"Monitored zero calibration" parameter field: Change the default value, if necessary
(setting range 0 to 100)
"Reset deviations" parameter field
