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.
