A. Because the capacity of electrolytic capacitors is much larger than that of general fixed capacitors, the appropriate range should be selected for different capacities when measuring. In general, the capacitance between 1 ~ 47μF can be measured by R × 1k, and larger than 47μF can be measured by R × 100.
B. Connect the red meter to the negative pole and the black meter to the positive pole. At the moment of contacting, the pointer deflects to the right largely (for the same resistance, the larger the capacity, the larger the swing), and then gradually turn left until it stops at a certain point, which is the forward leakage resistance that is slightly larger than the reverse leakage resistance. The leakage resistance should generally be above hundreds kΩ, otherwise, it will not work properly. In the test, if there is no charging phenomenon in the forward direction and the reverse direction, that is the needle does not move, which means that the capacity disappears or the internal circuit is broken. If the resistance measured is small or zero, it indicates that the capacitor is large leakage resistance or has been broken and damaged, cannot be use any more.
C. For the electrolytic capacitor whose signs are unknown, it can be discriminated by using the above method. Frist, measure the leakage resistance at randomly and remember its swing. Then, exchange the test leads to measure a resistance. In two measurements, the large resistance is the forward connection, that is the black meter is connected to the positive pole and the red one is connected to the negative pole.
D. Via the multimeter to charge the electrolytic capacitor from the positive and the reverse side, the capacity can be estimated according to the magnitude of the swinging.

The film, which critics are calling China’s ‘Dallas Buyers Club,’ earned nearly $50 million from pre-release previews and is being hailed as a creative breakthrough for the film industry.
China’s latest blockbuster, Dying to Survive, pulled off a rare feat of box-office magic this week: it managed to earn $50 million before it even opened.
A social drama tinged with black comedy, Dying to Survive premiered to rave reviews at the Shanghai International Film Festival in late June. It then hit the road on a promotional tour holding limited sneak-peek screenings in select cities across the country.
With each stop, enthusiasm swelled, and the film soon became China’s most widely discussed, critically acclaimed movie in years, scoring a 9.7/10 rating on ticketing service Maoyan.
The producers cleverly responded by escalating the scale of the previews, and the film began earning millions in prerelease revenue. They then moved its release date forward a full day to Thursday, citing “popular demand” — which only spurred more online excitement and discussion.
As of Thursday night, Dying to Survive had already earned $48.6 million — and it wasn’t even supposed to have been released yet. Maoyan’s box-office analysts expect the film to add as much as $100 million over the weekend, before ultimately earning upwards of $420 million.
So what’s all the fuss about?
Produced by Chinese hitmaker Ning Hao, Dying to Survive tells the story of a shady health supplements supplier, played by comedy favorite Xu Zheng (Lost in Thailand), who smuggles unapproved drugs from India to sell to leukemia patients who can’t afford the prohibitively expensive official medication offered by Chinese hospitals. Initially inspired by financial interest, the smuggler’s motives evolve as he realizes how desperately his customers need help.
The film is based on the real-life story of Lu Yong, a textile trader who was diagnosed with leukemia and spent over $80,000 on official medication before turning to smuggling a vastly cheaper generic alternative from India. He went on to save more than 1,000 lives by bringing the drug into China for other patients, before he was arrested and charged in 2014 with selling fake drugs.
Hundreds of leukemia survivors Lu had helped then petitioned for his release, and he was ultimately freed without penalty by a judge who praised Lu for the way he had never personally profited from the drug sales. After news of Lu’s saga spread, many in the local and international media began comparing him to the hero of Dallas Buyers Club, the 2013 Matthew McConaughey Oscar winner about a Texas man who sold unregulated AIDS drugs to help fellow HIV sufferers in the 1980s.
Critics have hailed Dying to Survive as a breakthrough for the Chinese film industry — a rare work of stirring social significance from a film scene typically blocked by censorship from addressing topics related to China’s real-life problems. Several preview screenings have ended in standing ovations .
