CEM DT-9989 Multimeter – Teardown & Review
An ‘extensive’ testimonial of a water-proof multimeter. This video clip is an unboxing, teardown as well as evaluation of the CEM DT-9989 Multimeter – an IP67 ranked Water-resistant TrueRMS Multimeter/ Oscilloscope with information logging as well as Bluetooth connection.
In March 2016 they opened up shop in the UK, so we’ve now got a market leader with affordable rates and also good supply degrees to complete against RS/CPC/Farnel. They supplied to send me anything I suched as from their magazine (up to a particular price limit) for testimonial. I ‘d been assuming of getting myself an OLED-screen multimeter for a while currently, so I jumped at the opportunity to obtain my hands on a really capable looking meter as well as have a play around with it for a couple of days.
This video is instead a lengthy one, but there were a heck of a whole lot of attributes on this multimeter to cover. It took me a number of days (and also concerning 10 hrs of recording) to try every one of the various points that this multimeter could do, and then another entire day to modify down all the footage into a watchable video.
Right here’s some links and also datasheets for the multimeter.
