Several precautions in the operation of electric spark leak detector:

1. When inspecting workpieces (such as glass lined tanks and short pipelines, small jobs), first connect the ground wire to the host, then clamp the ground wire clamp (on the outer wall of the glass lined tank) or fix other uncoated parts of the workpiece, and then turn on the machine and use a probe to inspect the coated parts.

2. If there is no exposed area to connect the ground wire after the anti-corrosion coating of the tested object (such as a long anti-corrosion pipeline and a workpiece that is completely coated without dew points) is wrapped, the ground rod should be inserted underground to check if it has good contact with the wet soil on the ground. If not, please excavate the dry soil part of the surface, fix the ground rod after seeing the wet soil, and then connect the host, ground wire, and ground rod in sequence before starting the machine to test the surface of the tested object. The anti-corrosion pipeline is very long: 1. Extend the ground wire 2. Move the bottom line. Special attention: IfinstrumentDo not use instruments without good grounding of the ground wire. If used, it can easily damage the instrument and the host may sometimes leak electricity. If you feel that the host is leaking electricity, please stop working immediately and deal with the grounding problem in a timely manner.
