AC/DC digital clamp meter
August 2014
Electrical Power & Protection
Megger’s DCM340 is a highly versatile instrument and is ideal for use in the installation, maintenance, monitoring or checking of AC or DC electrical systems and equipment. The DCM340 is capable of measuring AC and DC currents up to 600 A; AC and DC voltage up to 600 V; resistance up to 400 Ω; and frequency up to 400 Hz.
Current measurement combined with the comprehensive and accurate multimeter functions of the DCM340 eliminate the need to carry around both a clampmeter and multimeter, as this instrument does it all. The large clear digits of the numeric display are complemented by the high resolution digital bar graph, useful for indicating trending and fluctuation of measurement. The backlight assists use in poorly lit areas such as distribution cupboards and corners of switchrooms; and the data-hold feature enables use on difficult access cables where otherwise the display may be impossible to see.
Min/Max hold provides the ability to store the maximum and minimum DC or rms values over a period of time. While storage is taking place, either the present, maximum or minimum value can be displayed. Peak hold stores the maximum and minimum peak value of an AC signal at a 10 ms sample rate. The auto-off feature automatically places the meter in power-save mode after 30 minutes from power-on, but this can be disabled if required for min/max measurements. The DCM340 is safety rated to IEC 61010-1 Cat III 600 V and is drop-tested to 1,2 m onto a hard floor. It is supplied with test leads and a carry case, and a full one year manufacturer’s warranty.
