PMT20030 Transformer Polarity Tester
The Transformer Polarity Tester is a lightweight, hand-held instrument used for polarity indication of current, voltage
or power transformer windings with turns ratios from 1:1 to greater than 5000:1.
Transformers with fewer than 20 turns on one winding require 2 or more turns on the other winding for proper operation.
The instrument is designed to operate on isolated windings only and, as such, is not suitable for polarity indication of
autotransformers.
