Howdee all. I'm stuck with "that which I should not be stuck on" .... I can NOT locate calibration procedures nor component location diagrams for the 260XL series 6. Just about everything else seems to be out there, but not this one.

I'm not terribly concerned about fixing it once I get the info, and I hate to have to figure out which resistor is which the hard way if someone out there already has this manual. I've got the schematic. Just not a pictorial parts location diagram or a cal procedure.

Seems to be off on the low volts settings only, which offhand appears almost impossible since it looks like all the divider resistors are in series. ... but I gave up till I find a parts location diagram. And I'd rather follow a factory alignment procedure than make one up if at all possible.

Thanks
Barry

Have you tried Simpson?

Try here:

3/4 down on the page.... Army TB calibration manuals.

THank you pmeltech .. yes I did try that. I found it difficult to follow, at best, but if all else fails I'll give it a bit more attention. I was going to try for the parts position diagram first; it may be one of the lower voltage ladder resistors.

I did not try Simpson... didn't know if they would offer repair advice. The manufacturers seem to keep that stuff pretty tightly guarded but I shall do so tomorrow. Thanks.

Order of calibration is as follows;
50µADC
80mVDC
0.5mADC
5ADC
250VAC
2.5VAC

Sorry I cannot tell you more. I probably shouldn't even really say this much,
as I'm not really authorized to freely share the procedures.
You can probably extrapolate the rest from the Army manuals.
