Alternatively, you can place the probe with sensor cap directly in a
beaker or other container of water, making sure that the water does
not evaporate over time.
ERROR DISPLAYS AND TROUBLESHOOTING
Erroneous dissolved oxygen readings typically indicate a need to
clean the sensor cap, replace the sensor cap, and/or recalibrate the
instrument. First, clean the sensor cap following the instructions in
the Maintenance section and then perform a calibration. If
erroneous readings persist, inspect the sensor cap for damage
(cracks, large scratches in paint or dye layer), replace if necessary,
enter new coefficients and then attempt to recalibrate the
instrument.
If the sensor cap is not damaged, try to rehydrate the sensor cap
then recalibrate.
If you are still getting erroneous dissolved oxygen readings, try
replacing the sensor cap, enter the new coefficients and then
recalibrate. If the erroneous readings continue, contact JENCO
Technical Support to help determine the next step.
[Note:
If the meter still does not perform normally after the above
measures are taken, call
Jenco
Service Department.
