11 Troubleshooting
This section contains information on troubleshooting, CE Comments, and a
wiring diagram.
11.1 Troubleshooting Problems, Possible
Causes, and Solutions
In the event that the instrument appears to function abnormally, this section
mayhelptofindandsolvetheproblem.Severalpossibleproblemcondi
-
tions are described along with likely causes and solutions. If a problem
arises, please read this section carefully and attempt to understand and
solve the problem. If the problem cannot otherwise be solved, contact an
Authorized Fluke Hart Scientific Service Center (see Section 1.3). Be sure to
have the model number and serial number of your instrument available.
Problem Possible Causes and Solutions
Incorrect tempera-
ture reading
Incorrect R0, ALPHA, DELTA, and BETA parameters. Find the
value for R0, ALPHA, DELTA, and BETA on the Report of Calibra-
tion that was shipped with the instrument. Reprogram the pa-
rameters into the instrument (see Section 7.13, Calibration
Parameters). Allow the instrument to stabilize and verify the ac-
curacy of the temperature reading.
Controller locked up. The controller may have locked up due to
a power surge or other aberration. Initialize the system by per-
forming the Factory Reset Sequence.
Factory Reset Sequence. Hold the SET and EXIT buttons down

ment displays shows ‘-init-‘, the model number, and the firm

ware version. Each of the controller parameters and calibration
constants must be reprogrammed. The values can be found on
the Report of Test that was shipped with the instrument.

Blown fuse. A fuse may have blown due to a power surge or fail
-
ure of a component. Replace the fuse once. If the fuse blows a
second time, it is likely caused b the failure of a component. Al
-
ways replace the fuse with one of the same rating, voltage, and
type. Never replace the fuse with one of a higher current rating.
The Instrument

quickly or too slowly
Incorrect scan and scan rate settings. The scan and scan rate
settings may be set to unwanted values. Check the Scan and
Scan Rate settings. The scan may be off (if the unit seems to be
responding too quickly). The scan may be on with the Scan Rate
set low (if unit seems to be responding too slowly).
