The TPT420 is designed to offer a high degree
of safety. It conforms to standards DIN VDE
0682-401 and IEC/EN 61243-3. To ensure
that the unit is operated safely, please read
the following instructions before using the
device.
■
Do not use
the instrument in a humid
environment.
■
Before testing a live circuit the voltage
tester
should
be checked by connecting
to a known voltage source (e.g. a suitable
120 / 230 V outlet or a suitable proving unit)
before and after use.
■
Tests for voltage
should
be made with both
poles.
■
Extreme care
must be taken when testing
voltages above 50 V AC / 120 V DC.
■
Ensure the tester is only used within the
stated measurement ranges, in low voltage
installations up to 1000 V AC and 1500 V DC
and in the measuring category it has been
designed for.
■
When testing, ensure hands are behind the
barriers on the main body and remote probe.
Avoid touching the tips.
■
The instrument must be in good working
order and be clean and dry, with no broken
or damage to the leads, probes or case.
■
Do not use
the unit with the battery cap
removed and ensure when changing the
