Three Phase Reference Standard Meter high precision wide current range accuracy 0.05

KE9302A Three Phase Reference Standard Meter

KE9302A is widely used by power standard for the electric power departments, meter manufacturing companies and institutes of metrology. It can be used to precisely measure the voltage, current, power and other parameters of electric power circuit. And it is fit for all of the three phase energy meters test system with different modes.

General features:

1. High speed DSP and high accuracy ADC to make sure the quick and accurate measurement
2. Large screen color LCD display rich measuring info
3. Touch screen design, simple and easy operation
4. Completely independent measuring channel, greatly reduce the mutual interference
5. User-defined 3 channel pulse output, flexible configuration.
6. 3 channel pulse input could test 3 meters simultaneously
7. Various interfaces (including RS-232, USB,Ethernet, etc) to connect to PC or other devices.
8. Measuring data could be saved, browsing and displayed.

Functions:

1. Normal measurement(voltage, current, PF, active power, reactive power, apparent power, phase angle etc.)
2. Harmonic analysis
3. Accumulation energy test
4. Error measurement
