1. Expect with the conventional signal input and output functions,as well as resistance,Pt100,Cu50 RTD,thermocouple input-output 8 kinds of signals,very powerful. 2. All functions all use internal electronic switch,and some other brands on the market,unlike DIP switch auxiliary products need to exclude the impact of the mechanical structure life,but also improves the ease of use. 3. Two connector terminals,any level,regardless of the input and output terminals of the full use of these two,no longer have to forget plug lead damage to the meter or equipment to worry about. 4. V,mV,mA, ? input and output has a corresponding button,call directly,without advance menu selection,thermocouple,RTD input and output it is only after entering the function corresponding mV or ? files left a r r o w or right a r r o w to select it,the operation is very simple,no combination of keys,quick and easy operation. 5. Segment LCD clear display and used multimeter or a calculator is the same.Large display area,visual area of 49*29mm.Low power consumption,maximum power consumption of less than 0.3mA.It will be less than 10mA,when the backlight is opened.
