Specifications

一、     Function Brief
The use of micro-power consumption of the apparatus a high level of integration of high-speed embedded processors. The use of high-energy three 5 #  alkaline dry batteries or 5 # rechargeable batteries ,can be 0 ~ 4mA output current signal precision, 0 ~ 9999.9Hz precision frequency signals can be output 24V DC power,to apply  two-wire field devices; Can accurate measurement of DC 0 ~ 24mA current signal and frequency signal. Widely used in valve positioned, transducer, digital display, etc. and the majority of manufacturers of industrial and mining enterprises, to replace imported high-precision portable signal generator.
二、     Technical specification
◆        Power: Three 5 # alkaline batteries or high-energy or three 5 # rechargeable batteries, shutdown current <30uA; maximum working current <240mA (at 24mA output), three 5 # high-energy alkaline batteries can be used 3 weeks.
