9. Always use clean water to wash before immersing into different buffer.
NOTE: If you would like to exit the conductivity calibration mode without saving, please
press CAL/ESC key instead and it will retain the meter’s previous calibration data for
the current range.
PROBE MAINTENANCE
Electrode maintenance:
A) Make sure the electrode is clean!
B) Please store the electrode carefully, rinse it carefully in de-ionized water before
using. Please keep it under 0~50O C temperature after each usage.
Please plug the probe onto meter even during storage to shorten the activation time.
INSPECTION D.O. PROBE
Inspection probe while receiving a new probe or seeing strange reading or probe has
been used for one year.
1. It is fine to see electrolyte is not full. Only fulfill electrolyte and replace membrane
set when it is less than 1/2 full.
2. Be sure to check the central of the electrode surface. It should be clean in the
working area as below photo:
3. If the working area is not clean, check following section to clean it up.
