POSSIBLE CAUSE
pH electrode offset is greater/less
than +/-1.5 pH.
STAND was pressed before the
electrode and ATC/Temp probe settle
to within ±1.5 pH of the buffer value.
pH electrode is faulty
pH electrode slope is off by more
than 30% of ideal slope.
SLOPE was pressed before the
electrode and ATC/Temp probe
settled to within 30% of the buffer
value.
Buffer 4.00, 4.01, 9.18 or 10.01 is not
correct.
Temperature is out of the 0.0 to 60.0
°C range.
Measured pH is out of the 16.00/-2.00
pH range.
Measured mV is out of the 1250/-
2000 mV range.
Measured temperature is out of the
-10/120 °C range.

CORRECTIVE ACTION

Replace the buffer and/or
the pH electrode. Press ESC.

Allow sufficient time for the
electrode and ATC/Temp
probe to stabilize.

Return for service.

Check that the correct buffer
is used and that the
electrode slope is not off by
more than 30% from the
theoretical slope.

Allow sufficient time for the
electrode and ATC/Temp
probe to stabilize.

Replace the buffer and/or
the pH electrode. Press ESC.

Return for service.

Bring the buffer temperature
within range.

Return for service.

Bring the out of range unit
into the correct measuring
range.

If units are within proper
range, return product for
service.
