The sensor under test must always be removed from the calibrator after use.
There is risk that the sensor may become stuck.
Component life time can be shortened by continuous high temperature
operation.
Use of this instrument at HIGH TEMPERATURES for extended periods of time
requires caution.
Do not turn off the instrument at temperatures higher than 100˚C. This would
create a hazardous situation. Select a set-point less than 100˚C and allow the
Instrument to cool before turning it OFF.
Check that earth connection for the instrument is present and attach Power
