Main functions

It can output 0～30000A current for a long time

The action time of the test equipment can be synchronized

Automatic identification of normally open and normally closed contacts

Several calibrations can be connected in series at the same time to improve work efficiency

III.Performance characteristics

Using beautiful and elegant PVC panel

Display the test value of primary current and secondary current directly, which is convenient for test observation and record.

High measurement accuracy 0.5 class

High power, small size and strong load capacity

Small size and light weight, the volume is only 30% to 70% of similar products, and it is very convenient to carry.

IV.Operation

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

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

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

（4）The current riser has random output wires; the output external copper wires are selected according to 10A/mm2. (The standard configuration is two 1-meter test leads)

（5）The capacity of the equipment is designed for short-time work of 5 minutes.

V. Technical characteristics

1.Name and Classification
