2. INTRODUCTION
GPM-8212 Power Meter is a 16-bit CPU microprocessor equipped with
multifunction of full-digitized measurement, calibration and output. The
microprocessor has the advantage of high-speed sampling and calculation
function to accurately measure the distortion signal of waveform. Except for its
essential measurement on AC voltage, AC current, AC power, Power factor,
and Frequency, the power meter also provides additional features of PT/CT
ratio setting, display value holding, the value of maximum and minimum
holding, range selecting, auto-ranging and etc.
In order for an even more efficient and convenient communication, the
standard RS232 or RS485 is available as an option attached to the instrument.
The GPM-8212 is a low-cost, easy-to-use power measuring instrument.
