1.
During calibration,
the buffer solution
temperature exceeds
a range of 5~50
˚
C
2.
The buffer can not be
identified.
1.
Please adjust the buffer
solution temperature to the
appropriate temperature
range and make another
calibration.
2.
Please replace the buffer, or
maintain or replace the
electrode and make another
calibration.
Error3
The readout is unstable Please check whether there is
bubble or air in the glass end of
the electrode; maintain the
electrode or change a new
electrode, and make another
calibration.
Error2
SLOPE value exceeds
the upper or lower limit
1.
Replace the buffer solutions.
2.
Maintain the electrode or
replace a new electrode, and
make another calibration.
Error1
