Huazheng HZJY-30K 30kv Insulation Resistance Tester
I. Features
High-voltage insulation resistance tester, with 8 range: 500V, 1000V, 2500V, 5000V, 10000V, 15000V, 20000V, 25000V, 30000V,test up to 30TΩ, manual voltage regulation function.
● Strict accordance with the safety standards for design
● Insulation resistance range 30TΩ @ 30 kv
● Short circuit current can be adjusted, maximum 5mA (Can be ordered as high as 10mA, short circuit current products).
● Automatic display polarization index (PI), induced electric absorption test values than (DAR), and can test the leakage current and capacitance.
● Anti-jamming performance is superior, the interference current reaches 2 mA, still ensure accuracy of test instruments.
● 2 methods for power: use of lithium ion batteries, battery life can be up to 4 hours (10000V @ 100MΩ).
● Insulation resistance simulation column.
● Digital filtering functions, external influence deviation display value causing mitigation point using filter function.
● Perfect protection function, and the spare fuse prompt functions.

III.Instrument using
• measured DAR:
1.Select more than 1 minute length measurement.
2.Select the appropriate voltage and start.
3.The instrument automatically record 15 s and 60 s resistance, and calculate the absorption than after 60 seconds.
Absorption ratio calculation method: DAR = R60 / R15;
• measured PI :
1.Select more than 10 minute length measurement.
2.Select the appropriate voltage and start.
3.The instrument automatically record 15S, 60S and 600S resistance, and calculate the polarization index after 600 seconds.
Polarization index calculation method : PI= R600/R60;
• test connection points for attention
1. Tested to confirm product safety grounding, try not charged.
2. Confirm the instrument E end (ground) have been grounded.
3. The use of G terminal (protection ring) (this machine is of low voltage side of the screen)
When measuring high insulation resistance, the sample should be in the position a conductor surface protection between the two measuring end ring, and the conductor protection ring is connected to the instrument with a test line G side, try to eliminate the measuring error caused by the surface leakage current, security testing is accurate.
