KE7308 |
Portable Three Phase Standard Meter |
Accuracy : 0.05 / 0.1, Test method : terminal input or clamp CT , Protection degree : IP67, test the error of three phase energy meters and field electrical parameters of power grid |
Highlight:
· Wide current range (direct connection): 0.2A to 20A, the highest accuracy of each test point is 0.05%
· Calibrate the error of all electricity energy meters, checking the constant of the energy meter
· Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter in the same loop
· 7” color LCD display, All the parameters of each operation function can be displayed within one page
· Two operation modes: touch screen and keyboard. Easy and reliable operation..
· Measure voltage, current,frequency, power, power factor and phase angle
· Simultaneous measure and display waveforms of three phase voltage and current
· Measure ratio of CT.
· Allocate clamp of 20A, 100A, 200A, 500A,1000A to directly measure the comprehensive error
· Measure the 2nd - 51st harmonics of current and voltage
· Display vector diagram, judge the wiring right or wrong automatically
· Industrial grade engineering plastic suit case, which has a safety protection level of up to IP67.
· Read the information of energy meter with barcode scanner (optional)
· Battery, test lead power or external power for choices
· Communicate with PC, download calibration data through USB flash disk, RS-232 port
· Firmware can be upgraded through removed disk by users themselves
· Save and browse the testing data
