9 ERROR MESSAGES
During pH calibration the following error messages can appear on the display:
"ERR1”: The zero (pH
-6.86) calibration of the pH-electrode is out of range (± 1,00pH).
"ERR2”: The span
(pH-4) calibration of the pH-electrode is out of range (90%-105%).
Press the pH-button to stop the error message. During 10 seconds one of the following messages will
appear on the display:
"AH”: The zero (pH
-6.86) calibration of the electrode is out of range (± 1.00pH).
"SH”: The span (pH
-4) calibration of the electrode is out of range (> 105%).
"SL”: The span (pH
-4) calibration of the electrode is out of range (< 90%).
During EC calibration the following error messages can appear on the display:
"ERR3”: The calibration of the electrode is out of range (70%
-100%).
Press the EC-button to stop the error message. During 10 seconds one of the following messages will
appear on the display:
"SH”: The span (EC
-4) calibration of the electrode is out of range (> 130%).
"SL”: The span (EC
-4) calibration of the electrode is out of range (< 70%).
During temperature calibration the following error messages can appear on the display:
"ERR4” followed by “AH”: The calibration of the electrode is out of
range (±2,0°C).
Press the Temp-button to stop the error message. The instrument will continue temperature
measurement.
When one of these error messages occurs, check if the buffer solutions have the right values and that
the electrode is properly placed into the liquid. Check also if the electrode is properly connected to the
instrument. Start the calibration procedure again. When the error message still appears, contact your
supplier.
