Local operation without digital display

Introduction
Devices with a cover without an inspection window are supplied without digital display and
with key lock. If the device does not have a digital display or key lock, limited operation via
the keys is still possible depending on the lock mode.
Setting/adjusting zero point/limit point without digital display
You can set or adjust the zero and limit points without a digital display. Further modes can
no longer be selected.
