Maintenance; Calibration And Repair Services - Extech Instruments IRC350 User Manual

Setting the Temperature
The temperature set-point can be set to any value within the instrument's specified range.
Do not, for any reason, exceed the specified temperature range.
1. Use the up and down arrow buttons to change the set-point value (shown on the
bottom, green LED digit display). The display will flash at a fast rate when the set-point
is changed.
2. Press "SET" and the digits will stop flashing. The calibrator will automatically adjust the
target assembly's temperature to match the set-point temperature. The red LED
display will indicate the temperature of the target assembly.
3. When the set-point temperature is changed the controller switches the well heater on
or off to raise or lower the temperature. The displayed well temperature gradually
changes until it reaches the set-point temperature. The well may require 5 to 10
minutes to reach the set-point. Another 5 to 10 minutes is required to stabilize within
the stated limits of the set-point. Ultimate stability may take an additional 15 to 20
minutes.
4. Reduce the temperature to a value below 212°F (100°C) before turning the instrument
off.
Warning: Turning off the power at higher temperatures can damage the instrument.

Maintenance

With proper care the instrument should require very little maintenance.
If the outside of the instrument becomes soiled, it may be wiped clean with a damp cloth
and mild detergent. Do not use harsh chemicals or compounds.
Do not clean the surface of the well with liquids. Simply wipe with a dry cloth.
The calibrator should be handled with care. Avoid dropping or bumping the calibrator.
