5. HOW TO START UP
5.1 MEASURING HEIGHTS
The green light comes on when the probe comes into contact with the part being measured.
1. Taking the reference : drive the probe to the reference plane, the green light comes on
when the probe touches it. Briefly press the PRESET key (3) to zero the display or to
recall the memorized Preset value.
2. Measuring: press the UP key (13) and then the DOWN key (14) and probe another
surface. The green light will come on and the height will be displayed.
To display this height to 0.01 mm instead of 0.001 mm, press the RESOL key (5).
To convert to inches, press this same key (5) for a little longer (2 seconds)
5.2 MEASURING REVERSED SURFACES - MEASURING THE PROBE CONSTANT
When measuring reversed surfaces, the Z_CAL takes account of the probe constant, i.e. the
diameter of the ball probe and its deflection.
The master gauge supplied with the Z_CAL must be used to measure the probe constant (ref.
see § 15. Accessories) :
Press key (4) and touch one of the ground surfaces of the
cylindrical gauge. Release the probe and touch the opposite
surface. The probe constant value is displayed and then
memorized following release (it is kept in the memory until it is
replaced by a new value).
The constant must be retaken after changing probe or after modifying the probe’s position.
Reversed faces may now be measured by pressing the UP key (13) and by touching a
reversed surface with the probe : the green light comes on and the height is displayed.
Comment : Once the constant is memorized, both normal and reversed surfaces can be
measured, indiscriminately.
