Introduction

One kind of UNI-T brand new UT50 series
Multimeters is a 3 1/2 digit with steady function
and highly reliable hand-held measuring instrument.
The Meter uses large scale of integrated circuit
with double integrated A/D converter as its core
and has full range overload protection. The Meter
can measure DC current, AC current, DC Voltage,
AC Voltage, Resistance, Capacitance, Diode,
Temperature, Frequency and Continuity, which is
an ideal tool for users.
