Connection of sensors type Pt100, Pt1000, thermistor from 100 ohms to 10K.   


4. Подключение датчика Pt100, Pt1000 по трех проводной схеме. Замкнута только одна перемычка "Resistance 1". Схема подключения на рисунке.
4. Connect the sensor type Pt100, Pt1000 for three-wire system. Only one jumper closed "Resistance 1". Wiring in the figure.
Такое подключение позволяет учитывать сопротивление подводящих проводов, измерение получается более точным.   
This connection allows you to take into account the resistance of the lead wires, the measurement more accurate.

Universal module ADC. 12 bits. Adjustable gain (1-12 times) can accurately measure even small voltage

Three modes of operation:

1. ADC mode (jumpers open). Range of measurement is 0-3,3 V.

2. "Current" jumper installed . Mode input current up to 70 mA. Measurement accuracy - 1%. Range - up to 70 mA. Connection of current sensors.

3. "Resistance" jumper installed . Measurement of resistance of 0.1-10 ohms. Measuring accuracy up to 0.2% (with R ~ 1k).
