1. Overview
Handheld transformer turn ratio tester is a creative meter, with samll volume, light weight, handheld operation, easy to carry with. The product is mainly used to test transformer's turn ratio, CT and PT polarity testing, the testing speed is quick and with high accuracy.
2. Function features
(1)Powered by lithium battery or 220V AC, fully charged once, can continuously test hundreds of transformer's turn ratio group. The testin process is easy and convenient.
(2)Have blind testing function, go on turn ratio, group testing even unknow the high voltage or low voltage connection method.
(3)Add CT turn ratio polarity testing function based on common transformer, Z-type transformer, PT tested object's testing.
(4)Wide measurement range, high accuracy, the turn ratio testing range can reach to 10000, the testing accuracy guarantees 0.3% at the highest value 10000.
(5)Have reverse connection protection, output short-circuit protection, and other protective functions.
(6)5.6 inches large industrial highlight true color LCD, clear display even under strong sunlight.
(7)Configured with external printer, convenient for data printing.
(8)Can reserve in the tester or U-disk.
