Meggar DCM340 digital AC clampmeter is a highly versatile instrument and ideal for use in the installation, maintenance, monitoring or checking of AC or DC electrical systems and equipment. Current measurement combined with the comprehensive and accurate multimeter functions of the DCM340 eliminate the need to carry around both a clampmeter and multimeter – 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 switch rooms; 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 mini-mum 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.
