Safety precautions for the insulation volume surface resistivity tester
4.1 read the instructions before use, and follow the instructions step in operation.
4.2 do not use the accessories provided by the non original factory in order to avoid the danger.
4.3 when the test is carried out, the high voltage output of the high voltage output end of the instrument is on the end of the instrument, and the human contact is strictly forbidden, so as to avoid the electric shock.
4.4 in order to avoid the error caused by the insulation leakage test bar itself, the instrument for measuring input test bar should be suspended, do not collide with the external object.
4.5 when the insulation resistance of the measured object is high and the indicator is unstable, the clamp of the instrument measurement line can be attached. For example, for the insulation of cable core and cable shell, the two ends of the tested object are connected to the input terminal and the high voltage terminal respectively. Then the inner insulation of the cable core and the core is connected to the instrument "G" to eliminate the measurement error caused by the leakage of the surface. It can also be used with a shielding box, which is placed in a metal shield box and attached to the measuring line.
