Power-up & Warning Display Messages
At power up the tester performs a selftest and shows the
software version.
If all is well the display will indicate the mains supply
voltage, this screen is referred to as the IDLE screen.
If the tester detects special conditions at power up, for
example a dangerous condition, a warning message will
indicate the nature of the condition.
The adjacent table shows the messages that can be
shown when you power up the tester. The values are
examples and can differ from the displayed values.
