Troubleshooting and Service
At a specific freezing point, each probe has a unique resistance
which should vary very little from test to test. Therefore, the results
of this test may be used as a troubleshooting aid, in conjunction
with the sample-probe checks described in section Sample probe
checks and replacement, shown later in this chapter.
4. Record the sample probe resistance and bin number in the service
log at the end of this user’s guide (and/or other convenient
location); then press the STOP key.
The display will revert to Probe Bin Test.
5. Press SETUP and follow the procedure 2. Set Sample Bin # to reset
the sample probe bin setting as necessary.
Note Recalibration is required each time the sample probe is
replaced and/or the sample probe bin number is reset.
If running this test produces the message, Reset Probe
Configuration instead of the sample probe resistance and bin
number, the sample probe bin number is not available from the
instrument memory and must be reset.
6. Press SETUP and follow the procedure 2. Set Sample Bin #
described in Chapter 2 to preset a random sample probe bin
number, such as 5. Then press TEST and rerun the probe bin test.
Finally, as necessary, press SETUP and use the 2. Set Sample Bin
# procedure to correct the sample probe bin setting. If the Reset
Probe Configuration message persists, please refer to Chapter 5
Obtaining service to get help.
