I can not work without many "Digital Electronic Vernier Caliper" in my workshop.
However, they are always hiding them self when I am doing my job.
Lately I have discovered that they are missing the numbers on the display.
Both old and new ones.
Suddenly the numbers are being negative or shutting down.
I am blaming a Comunicacion tower not far?from the building.
Someone's that has a good advice for me?

Interesting vid I did years ago showing the effect of a CFL light bulb (the curly fluorescent ones before LED replacements) and the EMI interference it causes on a plastic caliper
LED lamps can be just as bad.? The SMPS supplies can put out quite an amount if EMI: Again - from years ago:
that's a TEK 1.8GHz analog spectrum analyzer
If you take something like an RF Explorer or one of those cheap CN-made spectrum analyzers into a place like LOWE's or Home Depot's out motion activated light aisle, watch the RF jump from about 1- 200 MHz...?? nasty.

Hi WAM
Maybe !!!!"
I just changed my roof lamp from a low Watt CFL to "150 W" LED.
I will test to morrow.
Maybe I still can get an old Edison lamp? It will also keep my workshop warm also? ?

We were doing FCC testing on one of our Large computers @ 1984-85 . One machine sailed right through & the 2nd after lunch started having problems , we put foil everywhere we could aloft with steel braid? with the rubber on the inside . Finally my boss asks me if the lights were on during the morning test & I said I was pretty sure they were not on . He goes over to the panel & hits every breaker that said lites & boom things got much better . He told the guy " I'm not paying you $ 125.00 a hr to find out you have bad ballast's . Those were the old 8' tubes with the 2 small pins on each side? HO's they were called back then .

I've found that the DROs on my mill become sensitive to electromagnetic interference when their batteries start to go flat.? So yeah, try replacing the batteries in? your affected digital calipers.

??? CFL's are great for makin noise , but so are some of the
import LED's too . I've seen a couple folks that have gotten? a
single AA? or maybe it was a AAA battery holder & solder the
leads to the battery contacts on the caliper ( digital ) &
then double stick tape or some other method of mounting the
battery holder to the caliper . Makes it real easy to remove the
battery . a lot of the cheapo's don't turn off when the power
switch is used , they just go to sleep . I bought my batteries for
these calipers at the Dollar tree for years & years 4 for a
buck . I think their up to the 5 buck mark? for 4 these days .

It seems that - as you'd expect - the off-brand ones put out the most noise.
I haven't revisited this? in a while.? I'll have to grab some newer LED incandescent? replacements and see if they've gotten better.? I do a lot of High Power LED PCB's for a local client and since they're for mil and marine we test them to various standards - MIL-STD-461, Part 15.109 and some Part 18...

I just do pre qual... they have to take the stuff to a real EMI lab or something like PAX ASIL - Spent lots of time there...

thanks . I have maybe 9-10 of those desk/bench lamps that ya can move just about anywhere . The older ones don't like the A19 Leds cause their so heavy , they won't stay where I put them. I bought a box oof I think 13/100 watt bulbs . I'm gonna see ifin I can't upgrade teh springs some to give them better manners .

When I GTAW the HF start really messes with all of my DRO's, and digital calipers/micrometers. ? It turns them on, turns them off, the displays show erroneous readings.? I thought they were possessed until I figured out it was the TIG's HF start that was causing the problem.? ?

Well it’s not just welders and LED lights…
" SOLAR STORMS ARE DRIVING FARMERS CRAZY:?Planting season is a hectic time for farmers. For many, it means working through the night using GPS-guided tractors to plant thousands of acres in a short period of time. The season was in full swing on May 10, 2024, when the biggest solar storm in decades struck Earth.?"Our tractors acted like they were demon possessed," says Elaine Ramstad, a Spaceweather.com reader and aurora chaser who helps out on a family farm in Northern Minnesota. "All my cousins called me during the May 10th storm to tell me that 'my auroras' were driving them crazy while they were planting.”
