1. Without entering the menu, the self-tuning function will be active by keeping pressing the "AT" button for a while.
2. Self-tuning AT is fast, stable and excellent, and with high precision.
3. Multi kinds of standard signal, thermocouple TC, thermal resistance RTD, analog quantity 4-20mA, and 0-5VDC and so on, are free to input, so as the measuring range.
The circuit of wide-width switching power, AC80-260V, is widely suitable to many kinds of voltage, good at resisting the interference of harmonic, and in good stablity. In one word, it can meet all the requirements from different working environments.
4. The deviation can be corrected, and the cold side of sense-transferring line can test the temperature alone. The amplifier of the cold side can return to zero by itself, the precision is ± 2%FS.

5. Main outputs:
"R"--Relay controlling AC contactor
"S"--Impulse zero triggering SSR
"I"--Current output 4-20 mA, impulse triggering Voltage regulator
"U"--Voltage output 0-5 VDC, impulse triggering Voltage regulator
6. Two kinds of independent output for alarming, 4 kinds of alarming ways can be custom-made.
