Temperature readout is not the
actual temperature of the
temperature block or incorrect
temperature reading on the display. Cause: Operating Parameters.
Solution: Check to make sure all operating parameters for the Product,
reference thermometer, and/or probe parameters match the Report of
Certification that was sent with the instrument and/or probe.
Cause: Electrical Interference
Solution: Look for sources of electrical interference, such as motors, welders,
generating equipment nearby, or ground loops. Try shielding wires, removing
ground loops, or changing location.
Probes stuck in the well at low
temperatures. Cause: Moisture.
Solution: If the Product has been used at low temperatures for extended periods
of time, moisture could possibly have built up in the well that formed ice. Set
the temperature high enough to melt ice to remove probes. Set the SETPOINT
to +100 °C and let the moisture evaporate out of the system.
Insert stuck in well. Cause: If maintenance has not been performed on the insert as described in the
Maintenance Section and the insert cleaned periodically, hard water build-up
on the insert may cause it to stick.
Solution: Use the special removal instructions in the “Insert Installation and
Removal Procedure” in Chapter 5.If this does not remove the insert, contact
Amphenpol Advanced Sensors Customer Service.
Password needed. Cause: Password is required to change certain parameters.
Solution: Enter password. The password by default is 1234.
