Troubleshooting of insulation oil withstand voltage tester:
1. Insulation oil withstand voltage tester has no display
Treatment method:
1.1 Check whether there is power supply
1.2 Check whether the fuse is blown. One fuse is located in the power socket and the other is located on the panel.
2. After the display of "operation", there is no pressure rise and no alarm
Treatment method:
The fuse on the panel is blown, replace a 5A fuse
3 When printing, the font is very small and does not move paper
Treatment method:
The printing paper roll is too tight. Open the printer panel and loosen the printing paper for several turns
4 The print is very unclear
Treatment method:
The printer ribbon has been used up. Replace the printer ribbon
Instrument maintenance:
1 The oil cup and electrode shall be kept clean. During the shutdown period, the method of containing new transformer oil must be used for protection. After the test of inferior oil, it must be washed with solvent gasoline or carbon tetrachloride and dried before continuing to use.
2 The oil cup and electrode should be checked once after being used for one month. Check whether the distance between the measuring electrodes has changed. Use a magnifying glass to observe whether the electrode surface is dark. If there is such phenomenon, readjust the distance and wipe the electrode with chamois or silk cloth. If it is not used for a long time, this work should also be carried out before use.
3 If the instrument is not used for a long time, please power on it once within a month for 1 hour.
4 If the instrument is not working properly, please check whether the fuse has been blown, and replace the fuse of the same model before continuing the test.
