Probewell MT-1/NT3 Meter Tester The
third generation of
our very popular MT-1/NT with 3-phase capability!
It is an ideal tool for
field-testing and periodic sampling. The meter under test is
entirely controlled by the test socket. No setup wiring is
needed. A complete test is done within a few minutes!
The MT-1/NT3 can test forms
12S, 14S, 15S and 16S self-contained 3-phase Wh meters along with
single-phase forms 1S and 2S.
The MT-1/NT3 can be set to
test all 3 phases simultaneously in one step (Mode Preset-quick) or
set to do a full test consisting of 3 phases simultaneously followed
by each element separately (Mode Preset-full). The MT-1/NT3 has also
reverse flow testing capability for solid-state Wh meters.
Comes with a
complete calibration report certifying measurement accu-racy
over its entire 36-point operating range using a primary
standard traceable to NIST.
designed removable tab with a twist and lock mechanism can be
easily moved by hand at 5, 6 or 9 o'clock.
