I wish to install a digital volt/amp meter between my transformer and TIU. I'm unable to find a suitable meter for my needs.
Any suggestions would be appreciated. Thank you

Excellent more recent discussion I was thinking of about this topic https://ogrforum.ogaugerr.com/...tmeters-and-ammeters

I know the below is not a digital ammeter but it shows how I measure amperage on my layouts three LW train transformers a quick installation without soldering.
I thought if the Amprobe ammeter would work I could use it for all three LW transformer and not have to install three ammeters on the two control panels.
The Amprobe ammeter has a small area to show the 0 to 5 amp range I would use for measuring train amps and is hard to read accurately in that small area.
Picture of the $25 Amprobe Clamp on Ammeter, full range 0-25 amps: note the compressed area of 0 to 5 amps on the left of the scale.
To amplify this area to 5 times its size, I made a simple 5 loop wire doughnut and rapped it with electrical tape. That changes the max reading from 25 amp max to max of 5 amps for the whole range of the meter.
Five coil wire doughnut installed and meter is rotated to each of three LW transformers

Here's a digital version from Harbor Freight for $15, and sometimes it's on sale, I bought mine for $10. It actually has very good accuracy, it was spot-on compared to my bench Fluke meter.

Thanks, Gunner, the next time that I am in an HF, I will get one.
