V. 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.
