does not prevent all heat from reaching the hub. Be careful when remov-
ing the heat shield or the probe from the well.
• DO NOT apply any type of voltage to the display hold terminals. Apply-
ing a voltage to the terminals may cause damage to the controller.
• DO NOT use fluids to clean out the well. Fluids could leak into electron-
ics and damage the instrument.
• Never introduce any foreign material into the probe hole of the insert.
Fluids, etc. can leak into the instrument causing damage.
• DO NOT change the values of the calibration constants from the factory
set values. The correct setting of these parameters is important to the
safety and proper operation of the calibrator.
• DO NOT slam the probe sheath in to the well. This type of action can
cause a shock to the sensor and affect the calibration.
• The instrument and any thermometer probes used with it are sensitive in-
struments that can be easily damaged. Always handle these devices with
care. DO NOT allow them to be dropped, struck, stressed, or overheated.
• The Factory Reset Sequence (see Section 12, Troubleshooting) should be
performed only by authorized personnel if no other action is successful in
correcting a malfunction. You must have a copy of the most recent Report
of Calibration to restore the calibration parameters.
