１．Various measurement functions

〇 Measurements of current, voltage, power, harmonics and phase detection are possible.
〇 True RMS: Indicates a correct value at the distorted waveform.
〇 Functions of PEAK, MAX, MIN, AVG are available. Easy to check the temporal change in the power source.
〇 LCD can display simultaneously the values of voltage and frequency or power and power factor.

2．Power measurement

Power measurement on any wiring system is possible.

KEW 2060BT can perform Single-phase 2-Wire / Single-phase 3-Wire and balance and unbalance measurements of Three-phase 3-Wire / Three-phase 4 Wire. The double display can simultaneously show many parameters like W & PF, W & deg, W & VA, W & Var, V & A, etc.

Various parameters such as active/reactive/apparent power, power factor, phase differences (1P2W only) which are required for the power measurement can be measured.

Total 3-phase power can be measured in simple steps.

By setting the CT and VT ratio and measuring the secondary side of the transformation, the primary side value can be obtained.

3．Harmonics measurement

Harmonics of the voltage and current, which cause various failures at the field, can be measured. It is possible to measure and show each voltage and current harmonics up to 30th.
Total harmonics distortion factor is in two types of THD-R and THD-F. Each degree of harmonics can be shown on the LCD of the tester. Both the current value (or voltage value) and the content ratio can be displayed on the same screen.

4．Phase detection
