Possible cause(s)
Corrective Action(s)
"Er1"
1. “Stand” was pressed
before the electrode and
ATC/Temp probe settled
to within +/-1.5 pH of the
buffer value.
2. pH electrode offset is
greater / less than +/-1.5
pH.
3. pH electrode is faulty.
1. Press “Clear” key, allow
sufficient time for the
electrode and ATC/Temp
probe to stabilize, re-press
“Stand” key to start the
calibration procedure.
2. Replace the buffer and /or
the pH electrode. Press
“Clear” key to recalibrate
meter.
3. Replace electrode.
"Er2"
1. “Slope” was pressed
before the electrode and
ATC/Temp probe settled
to within 30% of the
buffer value.
2. Buffer 4.00, 4.01, 9.18
and 10.01 is not correct.
3. pH electrode slope is off
by more than 30% of
ideal slope.
1. Allow sufficient time for the
electrode and ATC/Temp
probe to stabilize, re-press
“Slope” key to continue the
calibration procedure.
2. Check if the correct buffer
is used.
3. Replace the buffer and /or
the pH electrode. Press
“Clear” key to recalibrate
meter.
"Er3"
1. Temperature is out of the
0.0 to 60.0°C range.
1. Bring the buffer
temperature within range.
"over"
/ ”undr”
1. Measured pH is out of
the 0.00 to 14.00 pH
range.
2. Measured mV is out of
the –1999.9 to 1999.9
mV range.
3. Measured temperature is
out of the 0.0 to 100.0°C
range.
1. Bring sample pH into the
correct measuring range.
2. Bring sample ORP into the
correct measuring range.
3. Bring sample temperature
into the correct measuring
range.
