になる。The operation of the embodiment will be described below. FIG. 2 is a 70-chart showing the measurement operation. Before the measurement starts, the measurement mode data (relay type data, resistance value standard data, etc.) transmitted from the central control unit 6 is transmitted to the communication terminal. Next, when the measurement is started, the temperature measurement means 2 and the resistance measurement means 1 sequentially perform temperature measurement and resistance measurement.
The measured environmental temperature value T2 and the measured resistance value R2 are taken into the digital calculation means 4 via the interface 3. In the digital calculation means 4, the true resistance value RTI at the predetermined temperature T1 is calculated by the temperature correction calculation formula, and the true resistance value RTI after the correction calculation 1L is calculated.
A determination calculation is performed to compare the resistance value with standard data (upper limit value and lower limit value) to determine pass/fail. Next, after the result of the pass/fail judgment and the temperature-corrected true resistance values R and l are transmitted to the central control device 6 via the communication means 5, the above-mentioned measurement operation is started again. Here, in the present invention, the resistance value of the measurement countermeasure and the environmental temperature value of the measurement location are automatically measured, and the resistance value at a predetermined temperature is outputted by digital calculation using a preset calculation formula. Therefore, it is possible to easily perform temperature correction at any temperature.
It has been praised for its ability to always measure accurate resistance values and to reliably make pass/fail judgments based on standard data.
