Advanced jaw design means that the clampmeters’ accuracy is not actually affected by external magnetic fields or off-centre conductor positioning. Utilisation of Hall Effect technology ensures a broad flat frequency response resulting in optimum accuracy even when harmonics are present. True RMS Measurement By using True RMS measurement techniques the DCM R series avoids errors (up to 50%) which can occur when non-sinusoidal waveforms created by today’s complex loads are measured using traditional average reading techniques. True RMS measurements are available for a.c., d.c. (Amps, Volts) and a.c. + d.c. (Amps).
Safety & Convenience
The compact size of the instruments gives the user access to constricted locations. The jaw has a large aperture of 55 mm and is able to accommodate conductors with diameters up to 50 mm. The tactile barrier indicates to the operator a safe working distance for his hand to be from the live uninsulated conductors, providing added confidence when making measurements in hazardous voltage areas.
Wide Range of Applications
The high accuracy current measurement capability and full multimeter functionality of the DCM-R series satisfy a wide range of applications in service, maintenance and installation of machinery and industrial equipment. These battery powered instruments can be used for automotive diagnostics and converter-driven current measurements
The DCM R series of digital clamp meters have a four digit L.C.D. and are available in different versions for maximum currents of 200 A, 1000 A and 2000 A. They feature autoranging and auto-zeroing and can measure a.c., d.c., pulsed and mixed currents. Additional functions include the measurement of voltage, resistance, continuity and a diode test. The overall accuracy of 1,3% of the measured value has been achieved by utilising the latest microprocessor technology, plus the use of a true RMS measuring technique. This accuracy even applies when harmonics or complex waveforms are present.
The clampmeters have additional ranges of 400 V, 600 V, 400 ½, 4 k½ and allow diode tests as well as continuity tests with an integrated buzzer. Simply by pushing a button, it is possible to freeze the last value measured or to display the peak value on the four digit 12 mm high liquid crystal display. The analog outputs of this DCM series can be connected to an oscilloscope, chart recorder, datalogger or other measuring/recording equipment. A true RMS output is also available. The traditional measuring method for taking current measurements by inserting a shunt resistor or a current transformer has inherent disadvantages, such as the necessity to break the circuit conductor. The modern, competitively priced Hall effect DCM R series Clamp-on multimeters offer the user many advantages including the measurement of d.c. currents and non-sinusoidal waveforms.
