3. Zero-setting of measuring head
This chapter contains a description of the operations that must be performed on the
electronic amplifier and on the measuring head, in order to zero-set the gauging
system.
The procedure consists of two stages:
1. The machine tool and electronic amplifier are prepared for the zero-setting.
• Put the selector switch 6 in position
(Manual mode)
• Put the zero-setting potentiometer 13 at the center of its range.
• Load the master workpiece in the machine.
2. The gauging system is zero-set by acting on the measuring head and on the
electronic amplifier (see paragraph 3.1, “Mechanical zero-setting of measuring
head” on page 19).
It is advisable to carry out these operations with the utmost care, in order to obtain
the accuracy and repeatability that the gauging system can ensure.
