Symptom
Power on but no display
Display disappeared
Air bubbles adhere on
electrode
Action
1. Make sure the time of pressing the power key is
more than .3 seconds.
2. Check that the batteries are in place and make good
contact, minding polarities.
3. Replace new batteries.
4. Move the battery away for one minute and then put
back in.
Check whether the low battery icon was on before the
display went off. If yes, replace with new batteries.
1. Stir the electrode completely and dip it into the
solution at an oblique angle. Dipping the electrode in
vertically creates many air bubbles.
2. After soaking the electrode in solution for 15 to 30
minutes, inspect the electrode carefully to make sure
no air bubbles adhere. If they still exist, tap the bottom
of the container gently and stir the electrode to remove
the air bubbles.
3. If the above method is not working, remove the
electrode out of the solution and blow at the electrode
to remove the air bubbles.
Error Code Meaning
Parameter: Conductivity
---
E03
E04
Meter is in manual ranging 1;
however, the conductivity
measured value is higher than
1999uS.
Conductivity value is over the
range limit (19.99mS) or meter is
damaged.
The original temp. error results in
this error.
Press “UP” key more than 2
seconds to change the mode to
manual ranging 2 or auto
ranging.
Put the meter in standard buffer
(the buffer concentration must be
lower than range limit). If E03 still
appears, send back for repair.
Refer to below error code of
temp. After solving the error of
temp, E04 of conductivity will
disappear.
How to Handle?
Parameter: Temperature

E02
E03
Temperature circuit is damaged.
Temperature value is lower than
range limit (0°C) or temperature
circuit is damaged.
Temperature value is higher
than range limit (50°C) or
temperature circuit is damaged.
Send back for repair.
Put the meter in room
temperature for 5 minutes to
make the readying back to
normal. If E02 still appears,
send back for repair.
Put the meter in room
temperature for 5 minutes. If
E02 still appears, send back for
