Product Overview

The 72-7226 CAL DU from Tenma is a digital clamp meter. This stable, safe and reliable digital clamp multimeter is designed with large scale integrated circuits and A/D converter as the core as well as overload protection and novel structure which make them a superb tool for electricians. It measures AC/DC voltage, AC/DC current, frequency, duty cycle, resistance, diodes and continuity and also includes data hold, sleep mode and relative mode features. The resistance measurement range from 400 ohm/4kohm/40Kohm/400Kohm/4Mohm/40Mohm (±(1%+2)), frequency measurement range from 10Hz to 10MHz (±(0.1%+3) accuracy). It is 3 3/4 digit digital clamp meter with precise operation, fashionable structure and highly reliable 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. It complies with IEC61010, pollution degree 2, overvoltage category (CAT II 600V, CAT III 300V) and double insulation.

Test & Measurement


72-7226 digital clamp meter, Battery, Test lead, Carrying bag, English operating manual.


When measurement has been completed, disconnect connection between the test leads and circuit under test, remove the test leads away from input terminals of the meter and turn meter power off.


Do not input higher than 600V between the two meter’s input terminal to avoid electric shock and damages to the meter.
