Electric meter: 4 digit range intelligent current meter, voltage meter and ohmmeter.

1. Brief introduction
4 and half intelligent current meter, voltage meter, ohmmeter
DPA4 4 intelligent current, voltage and ohm meter has three ranges: big, intermediate, small.
Ranges and ranges decrease by 10 times. There are two alarm output circuits with RS485 or RS232 communication interface which could be connected to PC: one circuit is for range exceed alarm (or free set alarm); one is for direct current output of negative pole alarm.
It is equipped with RS485/RS232 communication interface to connect with PC.
