Application Examples 32_Precision Low Resistance Measurement with Temperature Compensation
For quality control, our customer requires to measure the resistance of hot copper coil windings. Texmate installed a Tiger 320 Series DI-50E meter. A constant current is passed through the coil and the resistance calculated. To compensate for temperature variation the infrared sensor monitors the coil temperature.
A setpoint indicates "PASS" or "FAIL" of the coil under test. The meter's decimal point is set for a display resolution in milliohms (0.001 ohms) The meter can be configured with temperature compensation for almost any conducting material.
