ATTENTION

Please go through the instruction manual before
using your meter and also pay attention to the
section VI. SAFETY RULES.

INTRODUCTION£º

UT2000 series are the large LCD DMM with
accurate reading, stable quality, multifunctional
and modern design of 3 1/2 and 4 1/2 handheld
digital multimeter used for measuring DC voltage
and current, AC voltage and current, resistance,
capacitance, frequency, temperature, positive diode
resistance, transistor hFE and short circuit testing.
It is suitable for engineering design, laboratory
testing and industrial manufacturing and repair etc.
