Instructions
Safety rules
Test begins, it should take a good test line, after turning the power meter.
The test is complete, you should turn off power to the instrument, after dismantling the test line.
When the meter is working, the body can not touch or near the test line.
Test the whole process, there must be full-time staff on-site supervision for safe operation.
