Specification:
Material: ABS Plastic
Size: 172.7*140.3*62.3mm/6.8*5.5*2.5in
Power Supply: 8*AA Batteries (Not Included)
Maximum Display: 2000 counts
Measuring Range:
1. Measure The Output Voltage
MH12: 50V-1000V, (50V, 100V, 250V, 500V, 1000V,).
2. Measure Insulation Resistance:
MH12: 0.1MΩ-10GΩ.
Absorption ratio and polarization index standard
Absorption Ratio DAR:
The ratio of the insulation resistance value at 1 minute to the insulation resistance value at 30 seconds.
Polarization Index PI:
The ratio of the insulation resistance value at 10 minutes to the insulation resistance value at 1 minute, to judge whether the equipment has affected the insulation resistance due to moisture
Insulating materials all have the absorption process and polarization process of charge after adding high voltage.
The power system requires that the polarization index should be measured in the insulation test of the main transformer, cable, motor, etc., and this data can be used to judge the quality of the insulation, quality and aging problems.
Function:
1. AC and DC voltage measurement;
2. Insulation resistance measurement;
3. 100 groups of data storage;
4. Automatic calculation of polarization index, absorption ratio;
5. Backlight and data retention function;
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
