SpritesMods has a 5-part write-up that shows how to add wireless connectivity to a Fluke 15B+ digital multimeter
All in all, I feel like I have succesfully diversified my multimeter assortment. I have a Fluke 17B I can use for daily work so I can enjoy quick continuity testing and non-irritating power-off features, and I have the 15B+ as a very capable second multimeter, with WiFi connectivity to show trends and to allow for any device with a browser to act as a remote display. It’s a shame I couldn’t figure out more of the way the main multimeter chip works to get direct access to the display, but the PWM-trick I did to show the IP-address is an alternative that is workable. Here’s a demonstration. As you can see, the multimeter has the IP of 192.168.5.117, and that’s what I enter into the browser.
