•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 12.1, 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 Re-
port of Calibration to restore the calibration parameters.
•DO NOT operate this instrument in an excessively wet, oily, dusty, or
dirty environment. Always keep the well and inserts clean and clear of
foreign material.
•The dry-well is a precision instrument. Although it has been designed for
optimum durability and trouble free operation, it must be handled with
care. Always carry the instrument in an upright position to prevent the
probe sleeves from dropping out. The convenient handle allows for hand
carrying the instrument.
•If a mains supply power fluctuation occurs, immediately turn off the in-
strument. Power bumps from brown-outs could damage the instrument.
Wait until the power has stabilized before re-energizing the instrument.
•The probe and the block may expand at different rates. Allow for probe
expansion inside the well as the block heats. Otherwise, the probe may
become stuck in the well.
•Most probes have handle temperature limits. Be sure that the probe handle
temperature limit is not exceeded in the air above the instrument. If the
probe handle limits are exceeded, the probe may be permanently dam-
aged.
