INFO
Calibration menu selection
Offset: Entry of a fixed value by which the mV value is dis-
placed.
Manual calibration: Initial settings for the function of the
CAL key.
Cal. settings: general calibration settings
Calibration timer: Clock for calibration
Autocal TopCal: Initial settings for the TopCal S
calibration.
0650 mV Enter Offset value for redox value
0000 mV Curr. PV: current measuring value (primary value)
Offset: redox value difference in mV
When you enter the measuring mode while an Offset is
active, "OFFSET" will be shown on the right top of the
display.
Calibration parameter
Data entry abs.: Enter the electrode offset in mV.
Calibration abs.: The electrode offset is calculated from
the difference between the current measured value and
the known buffer value.
Data entry abs.: Enter the electrode offset in mV.
Data entry rel.: Entry of two % calibration points to which
one mV value is assigned.
Calibration abs.: The electrode offset is calculated from
the difference between the current measured value and
the known buffer value.
Calibration rel.: Use of a non-toxic and unchanged sam-
ple and buffer.
Entry of offset deviation
of the mV value for the alarm function
If the offset deviates from the reference offset by the value
entered here, an alarm can be triggered.
SCC (Sensor Condition Check)
This function monitors the electrode status or the degree
of electrode ageing. Possible status messages: "Elec-
trode OK", "Low wear" or "Replace electrode". The elec-
trode status is updated after each calibration. When the
"Replace electrode" message appears, an error message
may be displayed.
