12.1 Troubleshooting
In the event that the dry-well appears to function abnormally, this section may
help to find and solve the problem. Several possible problem conditions are de
-
scribed 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
dry-well seems faulty or the problem cannot otherwise be solved, contact an
Authorized Service Center for assistance. Be sure to have the instrument model
number, serial number, and voltage available.
Problem Causes and Solutions
Incorrect temperature

Power the unit on and watch the display. If the first number displayed is
less than “-0005-”, the unit has been re-initialized. Initialize the system by
performing the Master Reset Sequence

The display is off Check the fuses.
Check that the power cord is plugged in and connected to the unit.
The unit heats slowly Check the Scan and Scan Rate settings. The Scan may be on with the
Scan Rate set low.
Controller locks up
Initialize the system by performing the Master Reset Sequence. If the unit
repeats the error code, contact an Authorized Service Center.
Master Reset Sequence:
The Master Reset must be performed on the cold side. However, both the
cold and the hot sides are reset. Hold the “SET” and “EXIT” keys down (on
the cold side) at the same time while powering up the unit. The screen will
display ”-init-”, the instrument model number, and the version of the soft
-
ware. The unit will need to be reprogrammed on both the hot and the cold
side for R0, ALPHA, and DELTA, and on the cold side for BETA in the cali
-
bration menu. These numbers can be found on the Report of Calibration
that was shipped with the unit.
Temperature readout is not
the actual temperature of the
well
With the unit stable, slowly rotate the unit. If no change occurs, the unit
may need to be calibrated. Contact an Authorized Service Center. If the
display changes more than twice the normal display deviation, another unit
in the area could be emitting RF energy. Move the unit to a different loca
-
tion and rotate the unit again. If the temperature is correct in this new area
or deviates differently than the first area, RF energy is present in the room.
If you have to perform the test in the effected area, use the comparison test
to eliminate any possible errors.
