Digital Tester Description:
Test voltage and insulation resistance measurement in broad rangetest
voltage ranges from 250V to 5kV, in 25V stepped setup, and able for
measurement of 5TΩ insulation resistance in maximum. Supports various insulation judgments. Data storage and upload function. Auto computation and display of PI (Polarization Index) and DAR (Dielectric
Absorption Rate). Stepped voltage test, Temperature compensation, temperature measurement, and leak current measurement.
to manually store 100 data, automatically record 10 groups of data (360
measurement points in maximum for each data group), and automatically
record date and time. Carrying case. Hard carrying case adaptable to field application is adopted. Chargeable batteries can be used at the same time. Able
to be loaded with 2# batteries and chargeable batteries at the same
time, and when capacity of one group of batteries is insufficient, it
can be switched to another group for further use.
Measurement of Insulation Resistance and Leak Current
Test Voltage: DC250V～5.00kV Test Insulation Resistance: 0 –5TΩ Max Test Current: 1mA Able to display insulation resistance, leak current, PI, DAR, and measurement time.
Stepped Voltage Test
Test voltage is gradually increased to measure variations of insulation resistances and leak currents under different voltages. Two types of stepped voltage values are optional, and measurement time can be selected for respective stepped stages.
Display of PI (Polarization Index) and DAR (Dielectric Absorption Rate) Able to automatically measure parameters of PI and DAR
Live line voltage measurement
Can test AC/DC voltage AC50～750V, frequency: 50Hz/60Hz DC±50～±1000V Measurement precision: ±5％rdg.5％dgt
－10～70℃ Measurement accuracy: ±1.5℃
Data Storage Function
to manually store 100 groups of data, and also able to automatically
record 10 groups of data, with each group able to store 360 measurement
points in maximum.
Data Uploading Function
to upload the store data into PC through USB interface, to be formed
into graphic charts and to be printed for filing, and also able to set
up and modify measurement parameters at PC end.
