If the corrective actions shown above for 'READINGS UNSTABLE' or 'OUT OF CAL
RANGE' errors do not work, thoroughly clean the Probe and try again. If the 'OUT OF CAL
RANGE' error persists, reset the calibration values to Factory Defaults (by deselecting the
electrode type then re-selecting it) then try again.
Remember:
The Probe Sleeve and End Cap form an integral, working part of the
Probe’s measurement system, and MUST be fitted during calibration and
measurement for correct operation.
10.3. Resetting to Factory Calibration Defaults
In some cases, if there has been a serious calibration error, the easiest way to rectify the
situation is to reset the Electrode to its factory defaults. To do this, first bring up the Socket
Assignment screen:
SOCKET ASSIGNMENTS
1:EMPTY
l
4:N/A
2:N/A
l
5:N/A
3:N/A
l
6:N/A
Move the cursor arrow to the right and change the electrode type to EMPTY. Press OK.
Next, re-enter the Socket Assignments screen and re-select your electrode type. This will
reset the calibration to default values.
Once factory calibration defaults have been restored, you
must
carry out a
full two-point
calibration
of the Electrode.
10.4. Calibration Data Storage
The AP-Lite contains its own microprocessor and memory. All calibration data, including
the GLP data, is stored within the Probe’s memory. When a Probe is connected to a Meter,
this data is transferred for display and logging.
This is a major advantage and allows you to use a variety of different Probes with a single
Meter, without the need for re-calibration.
10.5. Calibration Reports
At the conclusion of each successful individual electrode calibration, a single line
Calibration Report is displayed. This report contains the raw output of the electrode under
calibration, uncorrected for temperature.
These values can be recorded and used to track the performance and ageing of the
individual electrodes. Please note however, in order to maximise the value of this feature,
all calibrations must be performed at the same temperature otherwise the recorded values
will not be comparable over time.
