a brief introdction:
The Yokogawa YOKOGAWA power meter WT210 has a five-fold higher frequency range and approximately twice the basic accuracy, and provides a high-speed data acquisition rate, coupled with a compact design, making this digital power meter more worth having.
main feature:
1. Wider frequency range, suitable for various occasions
1) Low frequency measurement from 0.5Hz-Low frequency measurement from 0.5Hz can be used to evaluate the start of the circulator and motor;
2) Commercial electricity
Power accuracy is better than previous WT series products;
3) Inverter
The 100kHz frequency range can be used for accurate measurement of high-frequency equipment such as inverters.
2. Ensure accuracy: 1% -130%
3. Can measure various types of signals
1) Surge and maximum load status
It has the function of maintaining the maximum value of voltage, current and power: it can maintain the peak value of display voltage and current, the effective value of voltage and current and the active power, the maximum value of apparent power and reactive power on the display.
2) Half-wave rectification, intermittent control and distortion wave
Measuring DC components: In addition to measuring DC input signals, it can also accurately measure DC components in intermittent signals and half-wave rectified signals
3) Quick response, the display refresh rate is 0.1S: the measurement interval can be shortened to 0.1 seconds, which can capture the detailed information of transient phenomena; it can also improve the efficiency of product testing by shortening each measurement time.
