Penske 21015 dwell?

[Mike S]

 Picked up a Sears-Penske 21015 dwell/tach meter today and installed a new 4.5v battery.
I have no manual unfortunately. I'm trying to figure out how to calibrate the 'set line' setting but can't get the meter to move.
I verified the meter is working.
I assume this is for the points resistance measurements.
Does anyone happen to have this model by chance?

Thanks,
Mike

I have a manual for a 21019 if you think that will help.

Put the two leads together to get full scale deflection, then adjust for zero.
Meter ready for use.

 I was able to get it working last night. It’s been a while since I had to take out the DVM and troubleshoot a point to point wiring circuit (did that in the 70’s when I repaired TV’s back then) and it turned out to be a cold solder joint. A little sweating of the joint and presto…it worked. I can now get the zero set to function.
Nothing like seeing 'Made in the USA' label on something this old and still working.

Thank you for the replies!

My (J.C. Penney) dwell/tach meter is over 40 years old, solid chrome-plated die-cast housing, glass meter lens (not plastic), and still works great; they don't make them like this any more.  :-)
