1. Overview
UT15B PRO/UT17B PRO is highly reliable true RMS multimeter with auto backlight function. Equipped with its
built-in VFC anti-interference start mode, it can filter the carrier frequency interference from sine wave, various
distorted voltage signals, and stabilize the output voltage of measuring frequency converter.
UT17B PRO is equipped with frequency and duty ratio mode in DC/AC function and temperature measurement
function (resolution: 0.1°C).
This product comes with CE, cETLus certification according to CATIII 1000V/CATIV600V safety level obtained.
In addition, this series of products also give full function error detecting protection of up to 30kVA energy, to
ensure safer operation.
