🔴 Datron 1062 Multimeter Repair Part 1 SN_016117 - No.795

I start to repair a Datron 1062 which has no display.

I check the power supplies for correct function and test some of the common failures, I then find that the display is cracked.

I reverse engineer the display driver to work out how it can be modified to allow use of 7 segment displays instead, and design my own replacement display module.

I begin to do the conversion which I will finish in the next video, so make sure you subscribe and click the bell to see the entire process and display testing.

I will make my replacement display boards available for sale as soon as I have finalised the design and created formal instructions on how to convert the Datron for it.

I am always impressed with your tech skills.

Stacked PROMS are common in some equipment where they have CS lines on one device and /CS lines on the other, so they can double up on the capacity in 1 socket

Wow this was recommended to me. How did they know?! I have a Datron 1062 I repaired as well. Watching at this moment. Just had to comment now haha.

Thanks for the great video. I would cut back on the coffee.

[macmaniacal]

oh you've done a lot of datron repairs

[daveodessa]

You did a great job on replacing the broken display. Was there no chance of getting a direct replacement?

That was a real shame that the display was buggered :-(
Hopefully your led display doesn't need too much current, leds are greedy lol.
My mate had a racal counter with numerators, very sad looking.
I cut the high voltage and plopped new driver chips on a bit of stripboard, wired that to 7 segment displays.
Worked fine!, the psu didnt give a dam.
The idea was to make it easy to reverse if the numerators became available, they never did :-(.
I was wondering if you were going to do a similar thing, a temp setup so you can get the rest of the meter working.
Yes i know, a vfd, Chickens teeth lol.

Bro not a negative comment here but I use to watch this channel all the time for CB radio repair. Did you start another channel for that subject?
