Hi,
I have a Microball height gauge. I was using it today and noticed by accident that if you press down on the scriber, the assembly drops down from the micrometer head on a spring. There is a thumb screw to lock it – but never really use that.
Just wondered what is the purpose of this springing? Seems an odd thing to have as now I'm wondering if the assembly has returned home properly.
I'm sure there's a very good reason for it!?
Thanks,
Mike.
