UNI-T UT58D User Manual

Overview
Warning
To avoid electric shock or personal injury, read the
“Safety Information” and “Rules for Safety Operation”
carefully before using the Meter.
Digital Multimeters Model UT58D (hereafter referred to
as “the Meter”) is 3 1/2 digits with ex-large LCD, steady
operations, fashionable structure 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 has 28 different measuring
functions. It has not only can measure AC/DC Voltage,
AC/DC Current, Resistance, Capacitance, Transistor,
Diode and Continuity, but also have Inductance, Data
Hold, Full Icon Display, Overload Protection and Sleep
Mode features.
