2.7 Error message

When an error occurs, the error code is displayed in the display area 8 (see 1.2).

Such as error code 2 (Err2).

Err1

>

1999

Check that the electrode cap is
removed and that the electrode is
connected correctly and placed in the
solution to be tested. If the instrument
does not connect the electrode, insert
the shorting plug into the socket.

Err2

So that the temperature of the solution
to be measured is kept within the
specified range.

Err3

Please make sure the buffer solution
used is within the validity period.
Clean or replace sensor.

Err4

Electrode slope exceed range

120%

Please make sure the buffer solution
used is within the validity period.
Clean or replace sensor.

Err5

Meter can’t recognize the
buffer solution

|∆

Eref

| <

10mV

Pls make sure the buffer solution used
is within the validity period.
Check whether the same buffer is
reused during calibration.
