How it looks now
This is an Infratek 103A Wattmeter. It is made in Switzerland and measures power over a very wide range. I do not have a manual so I do not know the specs. It is a 6 digit meteer. It can measure AC+DC upto 50A and 1000V.
If someone has a manual, I would be very pleased with a copy.
How it looked when I got it
The meter was a gift from Circuits online member Tom. It was in unknown condition. The front panel was in a bad shape. I removed it and scanned it. Then I restored the picture with a photo program. I printed and laminated it and used sticky foil to glue it to the front. The result you see in the first picture.
