Meter Error Codes
• If the reading on the screen is flashing
, the value is out of range.
Perform the meter self test, clean the electrode according to the electrode user
guide and re-calibrate the electrode with new standards.
• If the
icon is lit and the reading is flashing, the sensor needs to be
calibrated according to the user’s set calibration interval or the pH slope is
outside the range of 85 % to 115%.
• Press
to clear an error code. Error codes show
on the middle line and
a set of three alphanumeric characters on the bottom line. Some of these codes
are errors, some are warnings and some are purely informational.

Keypad Failure
Repeat the self test. When the meter reads
, press all the keys,
including the power key, within five seconds of one another.
034
BNC Input Failure
Disconnect all the electrodes from the meter, connect the BNC shorting cap
to the meter and repeat the self test.

Datalog Full
Download the datalog to a printer or computer, turn the automatic datalog
feature off in the setup menu or change the datalog setting to
,

in the setup menu so the meter deletes the datalog points when the
datalog is full.

Remote Control Error
Check the programming instructions to verify the correct commands, names
and values.

pH Calibration
Standard Error
The millivolts measured during calibration are the same for two buffers.
Review the calibration procedure and verify that the electrode was placed
in the buffers at the appropriate time. Clean the electrode according to the
electrode user guide. Re-calibrate the electrode with fresh buffers.
109
Bad pH Slope or
Calibration Offset
Clean the electrode according to the electrode user guide. Re-calibrate the
electrode with new buffers.

Autosampler
Interface Error
The meter is unable to send a signal to the autosampler. Make sure that
the autosampler is properly connected to the meter.

Autosampler
Signal Error
The autosampler is unable to receive a signal from the meter. Review the
meter setup parameters and make sure that the baud rate of the meter is
set to 1200.
