@Caleb: It was new to me, I did not know that speaking multimeters are available in the market...and thanks for bringing these innovations to us; One questions that comes to me mind, how a visually challenged person would know where to place the probes on? Not sure how a talking multimeter helps them without assistance...any idea?
Yes, I agree that this feature would be very useful if the multimeter is out of line of sight. In the video I see that the user needs to press a button on the multimeter for it to speak. It would great if the voice is also automated and the multimeter should speak as soon as the value settles down. That would help in this kind of use cases better. The button could be kept for the user to listen to the multimetrer again.
This can be a useful feature for anyone who simply can't make out the display. Consider that being legally blind doesn't mean that you can't see anything. You may be able to make out the shapes of pads and such and still have a difficult time reading the display.
That being said, I've known people who were blind that worked in the IT industry, they found ways to get the job done, regardless of wether it was replacing a video card or troubleshooting an error on screen (text to speach doesn't work when your computer is crashed!
Oh yes, I agree. There have been so many times that attempting to balance the meter within eyesight while stretching my probes in an engine bay was enough to make me quit with frustration. Having it just call out the measurements would have been a welcomed feature.
