Description
TM-2212 is an AC/DC digital power meter with 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 wave form. Except for its essential measurement on AC/DC voltage, AC/DC current, AC/DC watt, power factor, frequency and Crest Factor, the TM-2212 also provides additional features of PT/CT ratio setting, display value holding, range selecting, auto-ranging, etc.
Features:
- Measurements: V/A/W/VA/VAR/PF/Hz/CF
- Large screen LCD display, 4 or 6 parameters displayed simultaneously
- True RMS V, A, W
- Auto calibration via computer
- Data Hold / Range Hold function
- High immunity to external noise
- CT ratio(1~9999)
- RS-232 and RS485 interfaces
