Thanks for this wonderful demonstration. my question is out of these four testers, which is the best one for testing capacitors?

Thank you Andrea. My OpenPli6.0 upgraded Dreambox now works like a sunshine. EPG timed TV recordings finally work without crashing in the middle of a program. OpenPli6.0 is about 15MB bigger than the old OpenPli4.0 about 45MB size version. Thanks to the mentioned Japhar SIM card it is possible to load much bigger firmware Images into the old model Dreambox.

I sure do hope the guy is okay! He was a younger man about 20 years ago. It is good of you to mention these safety protections Robert. I left Philips in December 2002 because my project stopped including the free Philips passenger bus. And he was one of the passengers of our (Vipre) bus. I know that Philips made an official rapport of what had happened that day, because it may concern health issues in years to come. The policy of Philips was very strict in these matters but it didn't prevent what had happened. And I'm sure that everywhere where people are at work mistakes are made, big or small! Always better safe than sorry.

Ouch! I'm glad the guy is ok. That's why I always recommend wearing hand and eye protection because you never know. I should also wear long sleeve shirts, but I hate long sleeves.

Thank you Justice. In case both my 3A adapters are not capable in delivering the current for the internal 2.5 inch hdd 1TB drive in the future anymore, or if they are beyond repair, I recently bought a 12V 5A power adapter (new just 8.25 euro on Aliexpress) to replace the old original 12V 3A Dreambox power adapters safely. The power plug exactly fits the dreambox powerinput jack. With compatible plug 5.5mm x 2.1mm.

Understood Robert. Sadly the danger with testing e-caps on our HV insulation testers is that when our e-caps are bad they likely may explode with a big bang before the given max capacitor working voltage is reached. And it may harm our meters and our health in the process! This will happen especially if the polarization on a lower test voltage on the e-cap plus and min poles is wrong. So replacing them straightaway like you said is always safer. In the past a colleague who worked like me at the Philips Medical Systems plant was covered one day by yellow electrolyte caused by multi wrong placed power e-caps that had exploded. The women at that plant must have placed the e-caps wrong in the mainboards he had to test which had caused this. He had to use a lot of washing machine soap to be able to remove the (carcinogenic) electrolyte from his skin! I do not think green environmentfriendly safe electrolyte exists yet?

Hi Albert,

I was referring to having an insulation tester included among our capacitor test meters, not necessarily for that 400V e-cap. My Smart Sensor AR907+ has 250V and 500V test voltages.
Most e-caps that I question would just be replaced straightaway if they aren't expensive.
My BK VOM is only good to 12V for an insulation tester.
