High Accuracy Reference Reading / 0.05% Reading
The HC 3100 is a new generation of advanced electronics intelligent instruments. Based on digital signal processing (DSP) technology, the HC 3100 is a multi-function precision power meter for three phase systems of 3 or 4 wires and single phase measurements. The measure-ments are comprehensive & fully auto-ranging covering 3 * voltage, 3 * current, active power (KW + KWH), reactive power (KVar + KVarH), apparent power (KVA), frequency, phase angle and power factor. All parameters are of high accuracy up to 0.05% reading.
Energy / Power Calibration Function
HC 3100 also provides energy / power calibration functions with digital input and output, and can be used as a master or sub-reference in measurement. The input is used to accept the measured energy signal when performming calibration function and the output is used as a reference to external comparator or reference standard.
Control Function
VFD illuminated display shows all the electrical measurement parameters in either 5 or 6 digits resolutions. All control and selection functions are simple and accessible with 4 function keys on the front of the instrument.
