Electrode Condition Icon
The electrode condition icon indicates the performance of the pH electrode or ion selective
electrode (ISE), based on the last saved calibration and electrode measurement stability.
Icon
Definition of Icon – pH Electrode
Definition of Icon – ISE Electrode
Electrode condition is good and the
electrode slope is 90 to 110 %.
Electrode condition is good and the electrode slope is
0 to 199 mV/decade (cation) or 0 to -199 mV/decade
(anion).
Electrode condition is fair and the
electrode slope is 80 to 120 %.
N/A
Electrode condition is bad and the
electrode slope is less than 80 % or
greater than 120 %.
Consult the electrode user guide for
instructions on how to clean, condition
and troubleshoot the electrode.
Electrode condition is bad and the electrode slope has
the wrong sign or the value is wrong.
Verify that the correct electrode ID was selected in the
setup menu. Consult the electrode user guide for
instructions on how to clean, condition and
troubleshoot the electrode.

Meter Error Codes
Over Range Measurements
If the measurement is flashing 9999 and over range, the measurement value is outside of the
allowable measurement range. Make sure that the electrode is connected to the appropriate
meter input and the electrode parameters are entered correctly in the setup menu. Clean the
electrode according to the electrode user guide and re-calibrate the electrode with new buffers
or standards. If the error persists, perform the meter self test.
Error
Code Description
E001
Display Error – If this error occurs, contact Technical Support.
E002
Hardware Error – If this error occurs, contact Technical Support.
E003
Channel 1 Input Error – Disconnect all of the
electrodes from the meter, connect the two BNC
shorting caps to the channel 1 and channel 2 BNC inputs and repeat the self test.
E004
Channel 2 Input Error – Disconnect all of the electrodes from the meter, connect the two BNC
shorting caps to the channel 1 and channel 2 BNC inputs and repeat the self test.
E005
Reference Input Error – Make sure that all of the electrodes are disconnected from the meter
(including the reference input), connect the two BNC shorting caps to the channel 1 and
channel 2 BNC inputs and repeat the self test.
E006
Ground Input Error – Make sure that all of the electrodes are disconnected from the meter
(including the ground input), connect the two BNC shorting caps to the channel 1 and channel
2 BNC inputs and repeat the self test.
E007
Keypad Failure – Repeat the self test. When the meter prompts, press each of the keys one at
a time, including the power key, within five seconds of the meter prompts. If the error persists,
contact Technical Support.
E008
Hardware Error – If this error occurs, contact Technical Support.
E009
Hardware Error – If this error occurs, contact Technical Support.
E020
Measurement Out of Range – Perform the meter self test, clean
the electrode according to
the electrode user guide and re-calibrate the electrode with new buffers or standards.
E027
Data Transfer Error – A communication error between the meter and computer occurred.
Check the cable connections and communication protocols. Make sure that the meter is set to
the correct baud rate and the computer function is enabled in the setup menu.
E028
Incremental Techniques Error – Make sure that the correct incremental technique was used
and all of the parameters were entered correctly. The measured millivolt difference may not be
great enough to permit the calculation of the unknown concentration. Increase the
concentration of the standard or dilute the sample. The concentration of the unknown may have
been calculated to be less than 0.0001. If the unknown was diluted, use a fresh aliquot of
undiluted or less diluted unknown. The electrode ID may be incorrect or the electrode may not
have been prepared correctly, filled with the proper filling solution or connected to the
appropriate meter input. If the error persists, measure a standard with a known concentration
and the same background as the sample. Adjust the standard concentration and volume until
accurate results are obtained.
E032
Printer Communication Error – A communication error between the meter and printer
occurred. Check the cable connections and communication protocols. Make sure that the meter
is set to the correct baud rate for the printer and the printer function is enabled in the setup
menu. The printer may be out of paper, the printer paper may be jammed or there may be
another printer error causing the printer not to be ready.
