LCD display, high-performance CPU chip, high-precision AD conversion technology and SMT chip technology,

multi-parameter, temperature compensation, automatic range conversion, high precision and repeatability

The current output and alarm relay adopt optoelectronic isolating technology, strong interference immunity and

the capacity of long-distance transmission.

Isolated alarming signal output, discretionary setting of upper and lower thresholds for alarming, and lagged

cancellation of alarming
