IX – SAFETY
- 9.1 – PT100 PROBE ABSENCE
When starting a test, the instrument automatically checks out the presence or absence of the
sample probe. In case of absence, the test can’t be performed, a warning message is displayed on
the screen and a buzzer sounds.
- 9.2 – DEFAULT IN SAMPLE TEMPERATURE INCREASE
The test automatically stops and a buzzer sounds when the recorded sample temperature remains
unchanged after 10 min of test.
- 9.3 – ELECTRIC SAFETY
An electric safety of the heating block is programmed in the factory at 550° C. When the safety
operates, a sound alarm with the following displayed message « High Safety » appears. To recover
the normal functions of the tester, it’s necessary to switch off the instrument and to start it again.
If the problem keep on occurring, the instrument has to be disconnected and the local distributor’s
maintenance department has to be contacted.
- 9.4 – SAMPLE TEMPERATURE SAFETY
The sample temperature safety is determined by adding X degrees to the expected test
temperature during the keyboard configuration procedure.
Limits are from +15 °C to +99 °C above the expected T°.
A buzzer sounds when the sample temperature reaches 15 °C under this limit. It’s then possible to
modify the expected temperature to carry on the test.
A buzzer sounds with a displayed message « Safety Stop » when this limit is reached : acquisition
by « ACQBUZZER ». The test procedure is cancelled.
The programmed difference between the expected temperature and the safety
temperature remains the same whatever the entered expected temperature.
