1.3.2Cautions

To avoid possible damage to the reference thermometer or to equipment under test:

●●Do not apply more than the rated voltage, as marked on the reference thermometer, between the inputs, or between any input and earth ground (30 V 24 mA max all terminals).

●●Unless recalibrating the instrument 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 instrument.

●●The instrument and any thermometer probes used with it are sensitive instruments that can be easily damaged. Always handle these devices with care. DO NOT allow them to be dropped, struck, stressed, or overheated.

●●DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environment.

●●Use the proper probes, function and range for your measurement.

●●Ensure probe coefficients are downloaded.
