Section 8 Troubleshooting
Problem Possible cause Solution
Decreased probe performance
causes slow stabilization and
prevents accurate calibrations or
measurements. The sensor cap is loose or
damaged. Tighten or replace the sensor cap. Always
replace the sensor cap and the iButton at
the same time. Refer to
Replace the
sensor cap and iButton on page 9.
Water is between the sensor
cap and the probe lens. Remove the sensor cap and dry the probe
lens. Refer to
Clean the probe on page 7.
The sensor cap is not
sufficiently conditioned. Keep the probe in the BOD bottle with
some water for more time, then try the
calibration again.
The temperature or pressure
sensor does not operate
correctly. Compare the temperature and pressure
readings of the probe with external
measurements. The pressure sensor
reads absolute pressure, which is not
adjusted to sea level. If the measurements
are not correct, contact technical support.
The lot code on the iButton is
not the same as the lot code
on the sensor cap. Replace the sensor cap and iButton.
Sample properties cause slow
stabilization or inaccurate
measurements. The measurement was not
adjusted for salinity in the
sample. Measure the salinity of the sample and
enter the value as a salinity correction
factor in the meter.
Procedure problem causes slow
stabilization and prevents accurate
calibrations or measurements. Air bubbles are around or
below the probe tip. Carefully tap or shake the probe to remove
air bubbles.
The LDO sensor cap is in
direct sunlight. Install the protective shroud.
The calibration mode in the
meter is set to factory. If user calibration is necessary, change the
calibration mode in the meter.
