So I have been working on this 625 and all of the resistors are way off so I’m replacing them with new ones. In the assembly manual I don’t see any calibration information and I can’t seem to find anything on the net. Am I missing something here. Is there no calibration on this unit? Seems unlikely. Any help would be awesome. Thanks guys.
@chris-anderson I have the same tester in my fleet. How far off are we talking? These normally had a pretty large tolerance of 20 percent. There doesn’t appear to be a calibration as everything is fixed aside from line and controls setup. I wouldn’t consider this as a precision tester either, as a result it is more of a go/no go kind of tester.
Radios + Tubes + Scopes + Cars= Nothing better!
@radtekman they were beond the 20% . iv heard that it is as you say go no go but that is better than me guessing it goes lol. this is mostly a project that im doing bucauls i knew the former owner.
Well I received the last of my parts and I passed all it’s test. Looks like we are good to go.
