Specification

Main unit

Power supply

Maintenance-free battery

Cable

30m, 2 pieces

Ambient temperature

-45~60℃

Display

Large screen LCD display, suitable for outdoor use.

Size

430*340*160mm

Weight

5kg

Measurement range & accuracy

Current

Cx=100μA~1000mA, Cn=100μA~1000mA

Accuracy: ±(0.5%+1digit)

Voltage

Vn=3V~300V

Accuracy: ± (0.5%+1 digit)

Dielectric loss

Tanδ= -200%~200%

Accuracy: ±0.05%

Capacitance ratio

Cx:Cn=1:1000~1000:1

Accuracy: ± (0.5%C+1 digit)

 

Capacitance

Cx=10pF~0.3μF

Accuracy: ±(0.5%C+2pF)

Note: actual measurement accuracy is related with current of test object and accuracy of PT (or CVT) in use.

Resistive current

Irp=10μA~200mA (peak)

Accuracy: ±(0.5%+1digit)

Capacitive current

Icp=10μA~200mA

Accuracy: ±(0.5%+1digit)

Other characteristics

Harmonic suppression

Waveform distortion of input current signal will not affect the measurement accuracy.

 Power management

 

When the battery power in the machine is low or has not been measured for a long time, it will give sound alarm and automatically shut down.

Charging time

12~24 hours in shutdown state, intelligent charging system, power-off protection after fully charges.
