Also, if the tab is out of the slot, knob may be easy to turn one way, hard
the other way. The meter "can" is spring loaded and follows a cam on top of
the meter. Sometimes the meter gets sticky and won't ride the cam. Going
"up" the cam works, but when you expect the meter to snap down and stay in
contact with the cam surface, it doesn't, resulting (maybe ) in this
behavior.

| Most likely the "slot" on the ASA knob didn't get into the right position,
| can't think of any other reason, but if they didn't couple well, the meter
| reading should be wrong.
