For best results is recommended to:
y
Calibrate the probe before use and recalibrate periodically
y
Keep the electrode hydrated
y
Rinse the probe with the sample before use
y
Soak in
MA9015
Storage solution for at least 1 hour before measurement
MTC mode
When the probe is not connected the “NO T. PROBE” message is displayed. The MTC tag
and the default temperature (25 °C) with blinking temperature unit are displayed.
1. Press CAL/EDIT and use the
keys to set the temperature value manually.
2. Press GLP/ACCEPT to confirm or press ESC (or CAL/EDIT again) to exit without saving.
Note:
The temperature value used for MTC can be set only when “NO T. PROBE”
message is displayed.
8.4. WARNINGS & MESSAGES
The Calibration Check feature flags diagnostic messages during a calibration. As electrode
aging is usually a slow process, differences between previous calibrations are likely due
to a temporary problem with the probe or buffers.

y
“WRONG BUFFER“ message is displayed blinking when the difference between the pH
reading and selected buffer value is significant. Check if correct calibration buffer has
been used.
