Chapter 4 Tips & Troubleshooting
Power -On Self tests:
When the tester is powered on, a number of messages can possibly
appear as the tester performs safety tests on itself and the mains power
supply.
Temperature monitoring
The tester is provided with temperature monitoring facilities to ensure
that prolonged tests do not overheat sensitive components. If, during
testing a ‘Over temperature’ warning is displayed, switch off any EUT,
and allow the tester to cool. This is provided to allow the EUT to be
switched off in a controlled way.
