PROBLEM CAUSE SOLUTION
From any screen
Invalid key;
Button does not
work in the current
operation mode.
Press alternate key.
Select valid buttons
depending on mode.
Ion CAL mode Ion slope calibration error;
calibration solutions are
outside acceptable range
(15 to 90 mV per decade).
Recalibrate using fresh ion
solutions. Use required ISA.
Replace electrode.
Ion CAL mode Calibration points
are more than 1
decade apart.
Recalibrate using
consecutive calibration
values 1 decade apart
(ex. 1.0 and 10.0).
Ion CAL mode Calibration attempted
with only 1-point during
ion calibration.
Recalibrate using 2 or more
ion calibration points.
pH CAL mode Calibration attempted
using only 1-point that
was not pH 7 (USA) or
pH 6.86 (NIST).
Recalibrate using 2 or more
pH points or use pH 7 (USA)
or use pH 6.86 (NIST).
Err with electrode
icon
Calibration error.
Buffer value does not
match value displayed or
electrode is disconnected
or failing.
Use fresh buffer solutions.
Check electrode connection.
Clean & recondition
electrode.
Replace electrode.
Ur (Under range)
Or (Over range)
Measured value is out
of range.
Electrodes not connected.
Electrode clogged, dirty
or broken.
Meter not calibrated.
Wrong temp value.
Make sure electrode is
connected.
Clean or replace electrode.
Recalibrate the meter.
Treat samples to bring
within meter measuring
range.
