red locking levers L1200
Without any doubt, this is a silly question...:-)
Recently I purchased a L1200 with VLS500.
There are two red hendle on the enlarger head, one on each side, the so called 'red locking levers'.
What the purpose of that, and how do you use it?
Not a silly question: I used to wonder exactly the same thing....
They are used when rotating the head. In the "-" position they provide click-stops (rather than an actual lock) to centre the head vertically. In the "O" position, the click-stops are disengaged to allow easy rotating of the head.
At least, that's in my enlarger - it is possible that they are supposed to lock and that mine are damaged....

At one side he's doing that correctly, at the other he doesn't click. A little investigation will be necessary! :-)
Do you have also the VLS version?
How can we controle the quality of the vc filters numbers?
With stepwedge? How to proceed?
I have the CLS450 colour head. I have no idea about the VLS head, sorry... If you do not have a manual for the head, try a Google search, or someone else here may have the head and can advise.
The click stops do not really matter as there is a scale under the head near the column that shows the head angle - just set it to be vertical.
