The precautions for using an electric spark detector are as follows:
Before use, the operator should carefully read the instrument manual, strictly follow the operating specifications, pay attention to protecting the instrument, prevent dropping, touching, and high temperature, and do not place it near damp and corrosive gases.
2. Choose an appropriate grounding point during testing to ensure the quality of the inspection.
(1) For the detection of anti-corrosion coating on the surface of small volume metal objects, the object to be detected should be supported by an insulator for more than 20cm, and then the grounding wire should be well connected to the metal object for detection.
(2) For the detection of large volume or flat objects, when the tested object has good contact with the ground, simply connect the grounding wire to the ground for testing.
During the testing process, the testing personnel should wear high-voltage insulated gloves, and no one should touch the probe and the tested object to prevent electric shock!
4. The surface of the tested anti-corrosion layer should be kept dry. If there is conductive layer (dust) or clean water, it is difficult to determine the location of the leakage point.
When the instrument is not in use, the power switch must be turned to the "off" position!
When the undervoltage indicator light is on, please make sure to charge it in a timely manner!
7. This detector is equipped with high and low voltage probes for users to choose from, and the panel meter reading should be determined according to the different probes used. If using a high-pressure probe, the reading should be based on the number on the top of the meter, otherwise, if using a low-pressure probe, the number below should be used.
