Introduction

The Probewell Lab MT-1/WT3 is a portable three-phase meter tester with built-in
WiFi technology.

MT-1/WT3 Overview

The MT-1/WT3 test socket adapter weighs only 6.4 lb which makes it the ideal tool
for field testing. Within a few minutes, a residential, commercial or industrial
electricity meter can be accurately tested on site by meter shop technicians.
The MT-1/WT3 can be set to test all three phases simultaneously in one step (Quick
Test) or set to do the three phases simultaneously followed by each element
separately (Full Test). The MT-1/WT3 provides measurements for active and reactive
energy with forward and reverse flow testing capability.
The MT-1/WT3 has a built-in three-phase phantom load made of synthesized 50A
current sources and a three-phase electronic standard with a typical accuracy of
±0.02% and a guaranteed accuracy of ±0.05%. It comes with a complete calibration
report certifying measurement accuracy across its entire operating range.
The MT-1/WT3 comes with a shock resistant carrying bag. The bag has individual
compartments for the test socket, the pickups and the User's Guide. There is also
enough space for small accessories such as the magnetic adapter for the optical
pickup, seals, pliers, etc.
Optional: A handheld remote is available for the MT-1/WT3, having a keypad and an
LCD display and weighing only 0.6 lb.
