During the period of no testing, they ought to be filled with new transform oil for protection. After testing tinpot oil, they must be cleaned by impregnant gasoline or pe

10、troleum aether. They can be used again after drying (60).2. Oil cup and electrodes must be inspected after one-month continuous testing. Regulator is used to measure if there is a change of electrodes spacing. Magnifier is used to investigate if surface of electrodes gets dark. If the phenomena occu

11、r, readjust electrodes spacing and clean electrodes with silk cloth. This work should be also taken if the instrument is not used for a long period.3. Shake sample softly, making impurity scatted well-proportioned. Make sure there is not any air bubble. Put sample into oil cup slowly. Make sure ther

12、e is not any air bubble. Do not touch electrodes, inside of oil cup and sample. Testing is taken in a dustproof dry place. Therefore, sample is not contaminated.4. Oil cup is placed horizontally. Ensure there is good contact.5. Cover the protective cover during testing, avoid getting an electric sho

13、ck by high voltage.6. Ground wire must be connected before testing (ground wire must be thick enough), so that safety of people and instrument is guaranteed.(2) Testing procedure1.

Points of Attention(1) Instrument must be well connected to the ground.(2) During the rising of voltage, protective cover must be covered.(3) The instrument is installed on the level and solid workbench.(4) After testing, use cloth to c

21、lean the oil on the electrodes of compression chamber, floor and protective cover. Keep all components clean. Oil cup should be filled with dry oil for the next testing.(5) Please contact with supplier for small cups. 7. Regular Malfunctions(1) Phenomenon: After motionless time, voltage does rise.So

22、lution: Check if protective cover is covered.(2) Phenomenon: After switch on instrument, there is no display and no prompt sound.Solution: Check if AC supply wire is connected and if fuse is in good condition (check fuse after disconnecting AC supply wire).(3) Phenomenon: During the start of testing

23、 and start-up, prompt occurs.Solution: Operate according to the prompt.(4) Phenomenon: Printer does not work.Solution: Check printer set if it needs to be printed, or maybe printer is not on the line.歡迎您選用ZHNY1801便攜式油介電強(qiáng)度全自動(dòng)測(cè)定儀，在使用該儀器前請(qǐng)認(rèn)真閱讀使用說明書第一章 概 述ZHNY1801便攜式油介電強(qiáng)度全自動(dòng)測(cè)定儀符合國(guó)標(biāo)GB/T 507-89和國(guó)際電工委員會(huì)標(biāo)準(zhǔn)I
