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 buffer solutions having the same value were used for the calibration.
Er.17: Calibration error. The calculated offset is too large. Redo the calibration. If the error persists, check the buffer 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 buffer solution or replace the electrode.
Er.19: Calibration error. The temperature (ATC or MTC) is outside of the specifications of the buffer solutions. Redo the calibration
Er.20: Calibration error. The file defining the set of calibration solutions is missing. Download it from our web site:

Er.21: Calibration error. The file defining the set of calibration solutions is not in conformity. Check that it is the right file. If you have
modified it, check the format; in particular, the decimal separators must be points, not commas.
Er.22: Recording error. Power was cut off while recording was in progress.
Er.50: Calibration error. Measurement error for the calibration.
