Fluke 189 with leaking surface mount supercap (also Fluke 287, Fluke 289)

<< < (50/64) > >>

M. AndrĂ¡s:
measured my 289 in stanby today. consumes over 600uA as my testo clamp says OL back to a chinese meter it says 650uA if you can belive to them in terms of accuracy, the was bought back in 2012 so its still well within warranty, will see what the distributor says in the next days

serggio:
My 287 after replacing super caps consumed 26,5 uA (238 uW)  in standby (OFF) mode.

Electro Detective:
Both 189 and 289 have the ongoing cRapacitor problem which I cleaned up with some isohol
and may swap out one day when I get the right part and patience to do without killing it
(since Fluke in Oz want receipts n s***, to verify first ownership to fix a -FLUKE PROBLEM- for an 'unimportant' long time loyal Fluke customer) 

Strangely enough, the battery life on both has been great for over 6 months now, on or off, backlight on, logging stuff etc just using ANY weird name brand cheapies

i.e. same set of cheap batteries going well for 6 months, and no leaks yet.

Am I lucky, or 6 months use on a set of cheapies is no big deal?

I haven't been removing or blocking the batteries either btw (lazy, forgetful, busy, whatever) and the meters are still going fine


The math is that 5 or 6 dollars in total to swap out twice a year on batteries for each feature packed meter sounds like a good deal,
and may be beat any leakage happening too if doing so every 6 months

Yeah, I think your right about the header being for the IR.  Slap in a Bluetooth and the device could be used better for data logging.

And for internal noise too  ;) Or you'll do completely EMI testing with all Bluetooth module's modes? Or will changing firmware for sending "sleep" signal for bluetooth module?
