4.1.1. STATUS LED
The STATUS LED can assume the following colour
OFF: Instrument
not
supplied.
GREEN:
Instrument ready for Test.
ORANGE: Test
running.
RED (blinking):
Instrument overheated. Please wait until LED status get back to
GREEN colour before executing new test.
RED (fixed):
Disconnect immediately the instrument form the circuit under
test. Check the nominal voltage range (220
415V) and the
frequency range (47.5
52.5Hz). Also check anomalous
situation in paragraph 6.1.5, 6.2.5, 6.3.5, 6.4.5 and 6.5.5.
