UNI-T UT151D Operating Manual

OVERVIEW
Brand-new UT151 series are 2000-count handheld digital multimeters featuring remarkably
stable and reliable operations. They are designed with the large-scale integrated circuits and
dual integral A/D converter and also offer overload protection for all ranges. The series can
measure DC&AC voltage, DC&AC current, resistance, capacitance, diode, transistor,
temperature, frequency, battery and continuity, which make it a perfect solution for your work.
