Directions for use
When the current will be measured goes through a transmitter, the current will be measured at the output end. (Note: The false wiring may result in the damage of the transmitter)
The output amplitude of the transmitter can be adjusted according to users’ requirements.
Custom design in the different rated input current and the output current available.
When installing, the overflow hole can be disassembled, it’s easy to use.
