Cleaning method of oil cup: 
(1)Repeatedly wipe the surface of the electrode surface and the electrode bar with clean silk.
(2)Adjust the distance between the electrodes well with the standard ruler.
(3)Clean three times with petroleum ether (other organic solvents are prohibited), following methods must be followed in each time:
①Pour petroleum ether into the oil cup, occupied 1/4~1/3 capacity of the oil cup.
②Cover the oil cup opening with a glass plate which is cleaned with petroleum ether, swag evenly for one minute. Please have certain strength.
③Pour petroleum ether out, dry for 2~3 minutes with a blower.
(4)Clean with pending tested oil sample for 2~3 times.
①Pour pending tested oil sample into the oil cup, occupied about 1/4~1/3 capacity.
②Cover the oil cup with the dried glass plate, swag evenly for 1~2minutes, please have a certain strength.
③Pour out the remained oil sample, then carry out withstand voltage test.

Cleaning method of stirring paddle: 
(1)Repeatedly wipe the stirring paddle with clean silk until no fine particle exists on the surface. Touching the surface of the stirring paddle with hand is prohibited.
(2)Clamp the stirring paddle with a nipper, immerse in petroleum ether for repeated washing.
(3)Clamp the stirring paddle with nipper, dry it up with hot wind.
(4)Clamp the stirring paddle with nipper, immerse in the pending tested oil sample for repeated washing. 

Storage of oil cup:  
Method 1: Fully fill the oil cup with insulation oil in high quality after the testing is completed, store the oil cup in a case,lock the case cover.
Method 2: Place in vacuum drier for storage after dried up and cleaned following above method.
Note : The oil cup and the stirring paddle must be cleaned following above methods before first testing and after testing of oil in bad quality.
