Directions for use
- After the instrument is correctly connected, connect the power supply to the rated voltage, and the green indicator light will be on at this time, the instrument will be in the monitoring state, and the indicator value is the insulation resistance value of the power grid (excluding the self check file).
- If it is necessary to judge whether the instrument works normally, self inspection can be carried out. Set the switch at the back of the instrument to the self inspection gear, and the instrument will carry out self inspection. When the instrument can carry out normal self inspection, the pointer shall indicate the position of 0.01MΩ, and the alarm red light will be on, and the alarm output terminal has output. After the self-test, the instrument must be restored to the normal alarm gear.
-
When connecting shore power, because the shore power system is a grounding system, the instrument will give false alarm, at this time, the switch can be adjusted to the "shore power" position; the instrument will indicate the position of 0.01MΩ, but the outputnormally open and normally closed contacts will not change action, and there is no alarm output.
Note
It is forbidden to use this instrument in the same network with other insulation resistance meters, including megger.
