Compact, all-in-one installation tester
May 1st 2007 Acompact, all-in-one
installation tester introduced
by Seaward enables
contractors to meet their 16th
Edition and Part P electrical testing
obligations.
The lightweight, handheld
Powertest 1557 is said to be the
smallest in its class and has been
designed for maximum portability
and ease of use.
Cordless probe technology
provides ease of handling and
enables probe contacts, instrument
and test results display to remain in
the operator's sight at all times.
Colour-coded tests for earth
continuity, insulation resistance,
loop impedance, line impedance,
RCD tests and voltage
measurements can be selected
easily using a large rotary switch
and simple push-button control.
Included in the test
specifications is a non-trip loop
test, automatic RCD testing, 100,
250 and 500v insulation test
outputs and the ability to zero out
test lead resistance for very low
resistance measurements. More articles from Seaward Group: |
