Automatic Discharge Function

WARNING

When an insulation resistance test is performed on equipment to 
be measured that contains capacitance components, a test voltage 
equivalent load is charged which may result in electric shock.  

A residual electric charge can be released through the internal circuit of the 
instrument.
After tests, follow the procedure below to release any remaining charge.

1 

Complete the test without removing the test leads from the equipment to 
be measured.

2 

The charge remaining in the equipment to be measured is automatically 
released in this instrument.

3 

During discharge, the TEST lamp blinks.

4 

When the voltage falls below approximately 10 V, the TEST lamp turns off.
