Section 8 Troubleshooting
Problem
Decreased probe performance
causes slow stabilization and
prevents accurate calibrations
or measurements.
Sample properties cause slow
stabilization or inaccurate
measurements.
Procedure problem causes

Possible cause
The sensor cap is loose or
damaged.
Water is between the
sensor cap and the probe
lens.
The sensor cap is not
sufficiently conditioned.
The temperature or
pressure sensor does not
operate correctly.
The lot code on the iButton
is not the same as the lot
code on the sensor cap.
The measurement was not
adjusted for salinity in the
sample.
Air bubbles are around or
below the probe tip.
The LDO sensor cap is in
direct sunlight.
The calibration mode in the
meter is set to factory.
Solution
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.
Remove the sensor cap and dry the
probe lens. Refer to
Clean the probe
on page 8.
Keep the probe in the BOD bottle
with some water for more time, then
try the calibration again.
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.
Replace the sensor cap and iButton.
Measure the salinity of the sample
and enter the value as a salinity
correction factor in the meter.
Carefully tap or shake the probe to
remove air bubbles.
Install the protective shroud.
If user calibration is necessary,
change the calibration mode in the
meter.
