Displaying control reserve
Display
The following menu is available for OXYMAT 7 and ULTRAMAT 7.
Main menu > "3. Maintenance & Diagnostics" > "6. Drift values" > "3. Control reserve" The
currently used control reserve is displayed (in %).
Additional information
The control reserve is an electronic value which compensates for zero point drift. The control
reserve is determined as part of the zero point calibration.
Control reserve can be taken up by frequently readjusting the zero point. A warning that
must be acknowledged is output if the consumption is greater than 85%. If the consumption
of the control reserve drops below 85%, the maintenance demand is deleted automatically.
To reset the control reserve, execute a normalization calibration → [2.20.03] Factory
calibrations OXYMAT 7 (Page 191). If you cannot reset the control reserve, contact your
service partner/employee.
