The online resistance testing system for hot oil machines collects real-time changes in resistance values in the test chamber. The online resistance detection system provides outstanding flexibility and testing efficiency for industrial applications, making it easy to create automated testing systems.

Equipment features:

When using four wire measurement, due to the four leads forming a current circuit and a voltage testing circuit respectively, the impedance of the voltage measurement circuit is high, and the current flowing through can be ignored. The leads of the voltage testing circuit have almost no current, so the final measured voltage is the voltage on the tested resistorR=U/I.

System functions:

1. Real time acquisition of multi-channel resistance data and temperature

2. Channel upper and lower limit settings, channel screening function

3. Real time display of resistance change rate, failed samples, and failure judgment values

4. Dynamic modification of reference resistance value function

5. Dynamic output of software reports
