Notices
1.Select the appropriate power supply (220VAC or 12VDC) based on on-site conditions.
2.The micro-rogowski coil sensor must be correctly installed to ensure accurate current acquisition (range 1-100kA).
3.Set the trigger current according to actual application scenarios (default 1kA) for optimal monitoring sensitivity.
4.Ensure reliable grounding of the device to avoid electromagnetic interference affecting measurement accuracy.
5.Regularly export stored data to prevent memory overflow (supports 9999 records).
6.The device automatically saves alarm data during power outage; restore power promptly to avoid data loss.
