Operation

(1) After the wiring is completed, check it again to see if there is any wiring error and whether the connector is in good contact.

(2) During the test, if there is any abnormal phenomenon such as sparking or no display when starting up, turn off the power immediately and recheck the wiring.

(3) In actual wiring, the current output terminals should form a loop, otherwise the instrument will not output current.

(4) The current booster has a random output wire; the output external copper wire is selected according to 10A/mm2.

(5) The capacity of the equipment is designed according to 1 hour of work.
