Precautions#65306;
1.The instrument is only used on power-off equipment. The grounding terminal should be connected to the grounding network reliably.
2.The instrument should be used in spacious, safe and reliable place.
3.The equipment under test is shifted to the maintenance state if the high-voltage lead is disconnected from operation state and could be cleaned. 4.The instrument could be tested only after good initial insulation test so as to avoid the poor insulation of equipment under test causing the damage of the instrument during the pressing process. |
