Industrial Electronic Test Equipment Single-phase Parameter Measuring Instrume
CN8716A Digital Electrical Parameter Measuring Instrument is a kind of intelligent instrument which uses digital sampling technology to analyse and process the signal.
It has the following advantages:
1. the measured signal value is true RMS;
2. direct digital display, which can reduce the human error of reading. 3;
3. the same applies to the waveform distortion signal;
4. one instrument can be used to measure multiple parameters;
5. easy to achieve intelligent, can be connected with the computer.
Input mode: voltage and current are floating inputs;
Measuring signal peak: voltage and current are 1.6 times of the range;
Conversion rate: about 8000 times/sec;
Display update: about 3 times/sec;
Overall power consumption:
Atmospheric pressure: (86~106) kPa;
Ambient temperature: (0~40)℃;
Relative humidity: ≤85%RH ;
Instrument working power: AC 220V±20V; (50~60)Hz.
