Audible tones
A simple selection of audible tones is used to supplement the visual display.
These help the user by providing intuitive feedback during testing. In addition
to warning about dangerous or unstable supply conditions they provide a very
quick confirmation that the measurement process is taking place and, upon
completion of the test, a warning if the results are likely to be regarded as a
failure.
The meaning of the tone for each individual function is covered in the table below.
Test lead inputs
The test lead input terminals are Red Active terminal (marked A) the Black Neutral
terminal (marked N) and the Green Earth terminal (marked E).
Test lead configuration
The AUTOTRIP can be used with 2 different types of connecting lead.
1 Ref: TL-3P Mains lead; 3 x 4mm plugs to a 10A plug
Optional Accessory
2 Ref: TL-RGB 3-Pole distribution board test lead set; that can be fitted
with either prod tips or crocodile clips as required. The 3 colour coded prods/crocodile
clips of the test lead should be connected to the corresponding Line, Neutral
and Earth terminals.
The leads are an integral part of the tester set-up and should accompany the
tester when being returned for re-calibration or service.
Warning
A continuous 2 tone
alarm
An unsuitable supply configuration such as a
mains supply with incorrect polarity or having the
leads connected wrongly will be accompanied by
the Red Voltage/Polarity warning LED flashing
Wait-Test in progress
A steady beeping
sound
Emitted whilst a measurement is in progress. The
same tone is sounded when used in Hands Free
mode to indicate that continual measurement is
being made
Test completed
A single beep
Sounded upon completion of a measurement to
indicate that the result is being displayed
Alert
A short 2 tone alarm
Sounded when a test returns a result that is likely
to be regarded as a failure e.g.30mA RCD
trip time test gives a result of greater than 300ms
