The WT230’s advanced specifications and its wide range of functions let you handle all your measurement applications from low-frequency equipment to high frequency inverters using a single power meter. One unit also handles standby low-power measurements and rated-power measurements

(functions available with the WT210 only).

WT230 WT210

●

Wide range of 5 mA to 20 A

The built-in 5 mA range lets you measure currents as low as 25 µA. This makes it possible to measure very low currents on such things as intermittent control equipment. The wide current range (5 mA to 20 A) means a single power meter can be used for applications such as Energy Star® measuremnts, to measure everything from standby-power to rated-power.

Notes

1. This equipment's apparent power (VA), reactive power (var), power factor (PF), and phase angle (deg) are calculated from voltage, current, and active power. (Therefore, if the input contains a distorted wave, the v alues may not match those of other measuring instruments based on different measurement principles.)

If either voltage or current falls to 0.5% of the range rating or less , then the apparent power (VA) and reactiv e power (v ar) are display ed as zero , and errors are displayed for power factor (PF) and phase angle (deg).

3. The sign of the var of each phase is displayed with +(positive). In the ∑var calculation, the var value for each phase is calculated with a negative sign if the current input leads the voltage input, and with a positive sign if the current input lags the voltage input. Then the value of ∑ var may be display ed with –(negativ e).

4. Apparent power (V A) and reactive power (v ar) cannot be calculated and displa yed at the harmonics measurement mode.
