Methods and Operational Safety Guidelines for Using a Ground-Down Conductor to Conduct a Tester
Ground lead down conductor tester adopts open top or vehicle mounted structure, the instrument is controlled by high-performance single chip microcomputer, can realize intelligent test process, large screen Chinese liquid crystal display, test current automatic or manual gear selection, test record editable user Information is saved and printed. It is a portable tester with a high degree of automation. It has the advantages of small size, light weight, strong function, easy operation, high precision, fast test speed, good retestability, intuitive reading, simple and convenient operation, and is ideal to meet the requirements of regulations. The dedicated instrument is designed for production and field testers. Specially used to measure the DC resistance of portable short-circuit ground wire and personal protection ground wire.
Ground lead down conductor tester operation method
1. Connection method: Red 50 meter line Fork is connected to the red terminal block I+, the small fork is connected to the red terminal post V+, the black 5 meter line is connected to the black terminal post I-, and the small fork is connected to the black terminal post V-.
2. First find out the downlead with the ground network connection as a benchmark.
3. One end of measuring line (50 meters, 5 meters) is inserted into the instrument terminal block, and the end with the test clamp is clamped to the reference point and the measured point (black test line is clamped at the reference point, and the red test line is clamped at each tested point). on).
4. In order to make the measured data correct, please handle the cleanliness of the contact surface of the measured point as much as possible.
5. After the cable is connected, turn on the power switch and the power indicator is on. The resistance value of the test is displayed.
Ground lead down conductor tester safety guidelines:
1. The instrument should be grounded reliably. After the test line is connected, it should be turned on. During the test of output current, the test line must not be dismantled to avoid accidents. After completion, the power must be turned off first, and then the test line must be removed.
2. Measure the ground lead and ground network resistance.
3. In automatic test, the instrument automatically outputs the maximum current according to the resistance of the sample; when selecting manually, please select the possible maximum current test, which will effectively improve the test accuracy.
