I would guess they do product development sprinkled here and there across the world, like many conglomerates. Managing that is a gong show though.

Dot matrix display is good but has to have good contrast. The display on the 287/289 contrast is quite bad. I used the 189/287/289 with the IR3000FC adapter. It works good.

Good Morning BeBuLamar, you said the IR3000FC worked with your Fluke 189.  The specifications only say that it works with the 287, 289 and 789.  Did it work just as well with the 189 as with the 289.  Thank you for your time. :-+

When I had the Iphone and run Fluke Connect on it the both the 189, 289 works poorly. Some version of the IR3000FC works partly some don't even work. I almost gave up.
When I retired I returned my Iphone to the company so I bought a Samsung Galaxie S23 and it works great with both the 189 and 289 equally.

All the real estate yet they didn't use bigger, more readable font from distance. Had to squint to read my 3000FC when not using the fancy wireless.

I never have problem with small text only with low contrast. I am a sucker for high resolution display and tiny fonts.

got a prototype working ;)

I asked around for ideas.  I was thinking about using IR or some analog RF.  possibly abusing spi ports and generating 'some kind of rf' from that can can be picked up remotely.  all I need is an on/off key pulse.  if I had access to car keyfob chips (on both sides) that would be what I'd use.

well, espnow can do the job quickly enough and with a single chip.  I was looking into lora or other radios but they all really need a local cpu of some kind.  they cant just turn on and be 'seen' from the receive side (that I know of).

it has to be fast.  cant afford to join an AP and get DHCP and so on.

espnow is just raw wifi frames (ethernet like) but does not do IP, does not need dhcp, etc etc.  it just blasts and then exits.

video demo shows 2 wemos d1 esp8266 chips.  the little box is a receiver (mode) and the raw chip in my hand is the sender; that would be on the probe body and you simply apply power to it via a momentary button and on power-up it shouts out an espnow packet.

you can see the delay in the 2 blue lights.

is that delay tolerable?  I think so but curious what you guys think.  if I take a reading and I'm watching where my probe is, if I get the reading inside 1/10 of a second or so (100ms) then I'm happy.  I think this meets that but I need to logic scope this to see the delay number.

thinking even an esp01 chip will do this just fine.  the 2.4ghz antenna on pcb is small enough.  no battery drain on standby since its literally a power button.
