Before use, the first to do in the following preparations:

(1) measuring equipment to be tested before the power cut off, and to short-circuit discharge, never allow live measurement equipment to ensure the safety of persons and equipment.
(2) the possible induction of high-voltage equipment, the need to eliminate this possibility can be measured.
(3) the measured surface to clean, reducing the contact resistance, to ensure the accuracy of measurement results.
(4) before the measurement to check whether megger in normal working condition, mainly to check its "0" and "¡Þ" two points. That shake the handle, the motor rated speed, short circuit megger should refer to the "0" position, should be open refers to "¡Þ" position.
(5) megger should be used on a stable, solid place, and away from the large external current conductor and an outer magnetic field.

Do the preparatory work, it can be measured, and in the measurement, but also pay attention to correct wiring megger, otherwise it will cause unnecessary errors or mistakes.

Precautions:
1.insulation resistance table when not in use to put in a fixed cabinet, ambient air temperature should not be too cold or too hot, should not put the waste on the wet ground, and to avoid the corrosive effects of air containing place (such as acids, alkalis steam, etc.) into.
2.should try to avoid severe long-term vibration, so the header pivot and jewel damage and affect the scale indication.
3.terminal wire connections between the measured object can not be used with wire, should be separately connected, not because of poor insulation and twisted affect the reading.
4.before and after taking measurements of the measured object must be fully discharged, to ensure equipment and personal safety.
5.when lightning or tape device near high voltage conductor prohibited measuring insulation resistance meter, only in the device is not charged and can not be carried out when other power by induction charging.
6.when the switch from slow gradually shaken handle fast, if found pointer zero allowed to continue to vigorously shaken to prevent coil damage.
