3.1.5. USE OF ANOTHER PH ELECTRODE
The electrode supplied with the instrument has an integrated temperature probe. If you use another electrode, one without an
integrated temperature probe, you must measure the temperature of the solution.
The instrument indicates that the temperature can be modied by displaying MTC next to the temperature.
MTC = Manual Temperature Compensation.
You must then correct the temperature displayed, using the ▲ and ▼ keys, so that it is equal to the measured temperature of the
solution.
MTC
The instrument corrects the response of the electrode for temperature.
To calibrate the electrode, always correct the temperature rst. And make sure that all of the buer solutions are at the same
temperature.
To connect your electrode, use one of the optional connection adapters (see § 1.2). These adapters also let you connect a PT1000
probe.

It is not possible to record a single measurement while the instrument is already recording.
A long press on the REC key starts or stops a recording session. The REC symbol remains displayed for the duration of a
recording session. Auto o is deactivated (this means that the instrument is in permanent mode) and the P symbol is dis-
played.
If the REC symbol ashes, a recording session has been programmed and is pending.
Before starting a recording session, make sure that the battery life is sucient, or else connect the instrument to an external
power supply on/to a wall outlet using a micro USB cord.
When the memory is 90% full, the MEM FULL symbol blinks. When the memory is full, the MEM FULL symbol stops blinking.
To see the records, you must use a PC and install the Data Logger Transfer software (see §4).

3.4. ERRORS
The instrument detects errors and displays them in the form Er.XX. The main errors are the following:
Er.01: Hardware malfunction detected. The instrument must be sent in for repair.
Er.02: Error in internal memory. Format it using Windows.
Er.03: The update of the internal software is not compatible with the instrument (the software is that of another instrument of the
line). Install the correct internal software in your instrument.
Er.10: The instrument has not been calibrated or the calibration is not in conformity. The instrument must be sent back to customer
service.
Er.12: The update of the internal software is not compatible with the electronic boards in the instrument. Reload the previous
internal software into your instrument.
Er.13: Recording scheduling error. Check that the instrument’s time and the time of the Data Logger Transfer software are the
same.
Er.14: Calibration error. The measured value is too far from the value of the standard solution of the selected calibration set. Check
that the solution used in fact belongs to the selected set. If necessary, return to the initial calibration (see §3.1.3).
Er.15: Calibration error. The stabilization time is too long.
Er.16: pH calibration error. Two buer solutions having the same value were used for the calibration.
Er.17: Calibration error. The calculated oset is too large. Redo the calibration. If the error persists, check the buer solution or
replace the electrode.
Er.18: pH calibration error. The calculated slope is too large (> 105%) or too small (< 85%). Redo the calibration. If the error per-
sists, check the buer solution or replace the electrode.
Er.19: Calibration error. The temperature (ATC or MTC) is outside of the specications of the buer solutions. Redo the calibration
in a room where the temperature lies within the specications of the buer solution (see the pH_Set.csv le §4.3).
Er.20: Calibration error. The le dening the set of calibration solutions is missing. Download it from our web site:
