Introduction
The Megger TPT420 voltage tester provides
electricians and electrical engineers with voltage
indication and has additional functions / features
that makes the instrument more versatile.
The TPT420 features both LCD and LED displays
that provide AC and DC voltage measurement
from 12 to 1000 V AC and 1500 V DC and in
addition, a continuity function ranging from 0 to
500 k
W
. Continuity and voltage measurements
are accompanied by an acoustic sounder.
A bright LED torch feature allows safe working in
poorly lit environments.
When conducting a test between phase and
earth on a circuit protected by an RCD, RCBO
and Safety Breaker, the TPT420 will not trip
these devices.
The phase rotation indication function is
simplified which avoids the crossing of the test
probes adopted by some 2 pole testers.
With safety in mind, the TPT420 is CAT IV 1000 V
with an IP64 rated housing that provides an easy
and comfortable grip. GS38 shrouds are provided
as standard.
The unit has a feature that will warn the operator
of dangerous test voltages even when the
batteries have become exhausted.
Please note: To comply with GS38 (minimum
exposed tip) the metal caps on each prod must
be unscrewed and replaced with the supplied
plastic tip shrouds.
