DCM1500

1500 A TRMS clamp meter

DESCRIPTION

Measuring up to 1500 A ac or dc the DCM1500 also offers 750 Vac and 1000 Vdc ranges making the instrument ideal for use in the installation, maintenance, monitoring or checking of large a.c. or d.c. electrical systems and equipment.

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 d.c. 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 a.c. 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.

Using the Relative mode (REL), a stable value can be stored, the instrument zeroed at that point, and then any variation from that value is displayed as a direct measurement relative to it.

The DCM1500 is safety rated to IEC 61010-1 CAT IV 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 1-year manufacturer’s warranty.

APPLICATIONS

The DCM1500 is designed to be used on electrical systems and equipment where there is a need to measure current, volts, resistance and frequency. It is therefore intended for use while installing, maintaining, fault-ﬁnding or monitoring those systems.

The tactile barrier below the jaws of the instrument ensures a safe working distance for the operator’s hand when measuring current on live uninsulated conductors, although additional personal protection must still be used.

The min/max and peak-hold enable maximum load currents from equipment to be identiﬁed such as start-up currents to motors and heaters.

With the added beneﬁt of d.c. current measurement, it can also be used in applications including domestic power generation from solar panels and wind-turbines; battery monitoring; automotive uses for charging and load circuits; electric vehicle servicing such as fork-lift trucks; lift maintenance; UPS commissioning, servicing and maintenance; electro-plating plants and welding equipment servicing.

True RMS Measurement

By using True RMS measurement techniques the DCM1500 avoids the errors which can occur when non-sinusoidal waveforms created by today’s complex loads are measured using traditional average sensing clamp meters.

AC Conversion Type: * add 2 digits to accuracy when reading less 15% of full scale. AC Conversions are ac-coupled, true rms responding, calibrated to the rms value of a sine wave input. Accuracies are given for sine wave at full scale and non-sine wave below half scale. For non-sine wave add the following Crest Factor corrections: For Crest Factor of 1.4 to 2.0, add 1.0% to accuracy. For Crest Factor of 2.0 to 2.5, add 2.5% to accuracy. For Crest Factor of 2.5 to 3.0, add 4.0% to accuracy.
