The zc-320 leakage protector tester developed by our company is mainly used to test the leakage action current, leakage non action current and leakage action time of the leakage protector. The test current is 0-500ma, which is divided into ten levels, the time test range is 0-799ms, and the 16 character blue screen liquid crystal display. The tester is hand-held, small in size, light in weight and easy to carry. It is a high-quality testing instrument for field or indoor detection of various leakage protectors.
But when using the leakage protector tester, you should also understand the precautions, so as to avoid unnecessary errors. So here is a brief summary of the precautions of zc-320 leakage protector tester.
1. "Test line" and "ground line" must not be connected wrongly. Red to red is connected to 220V (live line) or phase line, black to black grounding pile or zero line. Sometimes the loosening of grounding pile (poor grounding) will also cause test failure. Please pay attention to distinguish!
2. When the "on / off" button is turned on, if it is found that the indicator light is dark and the LCD screen has no display, which may be caused by the lack of battery, the back cover of the battery can be removed with a cross screwdriver on the reverse side of the instrument, and the battery of the same model can be replaced.
3. In the process of use and carrying, it shall be handled with care, free from strong turbulence, vibration and collision, and shall be protected from the erosion of chemical reactants.
4. In the process of normal use, if the customer finds any defective product, the customer shall enjoy the after-sales service of replacement or repair within the warranty period after being tested and confirmed by our approved engineering testing personnel.
The above is the basic precautions for the use of zc-320 leakage protector tester. If you do not understand anything else, please consult our company for details.
