Product Overview

The 72-7745 CAL DU from Tenma is a hand held digital multimeter. It is a true RMS 4000 count auto ranging digital instrument featuring stable performance, high reliability and overloaded protection for all ranges. The orange and grey coloured meter is designed with large-scale integrated circuits and dual integral A/D converter as the core which can measure AC & DC voltage, AC & DC current, resistance, diode, continuity, frequency/duty cycle and temperature. The 72-7745 is double moulded for casing to ensure perfect insulation and offers backlit function to facilitate measurements on dark sites. In addition to the conventional measuring functions, there is a RS232C standard serial port equipped with model 72-7745 for easy connection with computer to realize macro recording and monitoring and capture of transient dynamic data, displaying change of waveform during measurement, providing data and evidence to engineering technicians for scientific research.

Test & Measurement


72-7745 multimeter, Battery, Test lead, Alligator clip, RS232 interface cable, PC software CD, Point contact temperature probe, Operating manual.


The rotary switch should be placed in the correct position and no change of range made during measurement to prevent damage of the meter.


When working at an effective voltage over 60VDC or 30Vrms AC, special care should be taken there is danger of electric shock.
