In consideration of this situation, this paper will simply teach you some solutions to dielectric loss of insulating oil and common faults of resistivity tester, so that you can work more efficiently.
1. The screen displays "electrode cup short circuit"
Treatment: first check whether the positioning groove of the inner electrode and the outer electrode is aligned, and then check the "inner electrode"
Whether the installation is loose mainly depends on whether the 7 in the figure below is loose.
2. The screen displays "please conduct [empty cup calibration]"
Treatment method: when the capacitance value of the empty cup is not within 60 ± 5pf, empty cup calibration is required; ① the internal and external electrodes of the oil cup are not placed properly or the internal electrodes are not assembled well, with discharge; ② the oil cup is not clean, and impurities between the internal and external electrodes need to be cleaned.
3. After the buzzer rings for 5 times, the instrument returns to the startup interface.
Treatment: ① check whether the capacitance of empty cup is within 60 ± 5pf, ② check whether the oil cup is put
OK, is there any discharge.
4. In the case of DC resistivity, the electrochemical time does not change for 60 seconds.
Processing method: check whether the clock of the instrument is running and adjust the clock.
5. What to do when the set voltage parameter bit display is not zero?
Processing method: use the [decrease] key to make the set voltage minimum, and then use the [increase] key to adjust.
The above are the faults and simple handling methods that are easy to occur when zc-211 insulating oil dielectric loss and resistivity tester is used. I hope you can help me. Of course, if there are other faults, please don't handle them without permission. Please contact our customer service in time, and our relevant technical personnel will judge the faults to avoid unnecessary losses.
