OFFSET CALIBRATION
The instrument can be calibrated according to one's needs. This consists in
setting an offset
(positive or negative
value) to be added to the value of the measured diameter.
When an offset value is set, this icon appears on the display
To access the Calibration menu, select
Setup (F1) → Setup HWS.1 → Calibration
At this point the available options will be displayed
: Offset
,
Diameter
and
Factory
.
At the side of entry Offset, the value of the offset in use is shown: decimal values referring to the selected
measurement resolution are black, while subsequent decimal digits are grey.
Select the desired entry by using the
arrow keys
(
F2
and
F3
) and the
Enter
key (
F1
).
OFFSET
This directly modifies the offset value even without any product in the measurement field.
By selecting the entry, a window opens with the value of the offset in use: values referring to the
selected measurement resolution are black, while subsequent decimal digits are grey.
Use the
arrow keys
(
F2
and
F3
) to modify the value viewed on the display in black, namely the
value referring to the currently set measurement resolution.
Every time you press the key
(
F3
) the value increases by a decimal unit
Every time you press the key
(F2) the value decreases by a decimal unit
An increase/decrease in the decimal unit refers to the selected resolution, namely the last of the black digits.
Every time you press the
arrow keys
(
F2
and
F3
) the instrument beeps. If you keep the keys
pressed, the increase/decrease will be continuous.
Once the desired value is viewed on the display, press
Enter
(
F1
): if the changed offset value has been
correctly stored, the instrument will emit a long beep.
To exit without saving the changed Offset value, press
Exit
(
F4
)
DIAMETER
This modifies the offset by viewing the diameter of a master in the measurement field
Selecting the entry opens a window where the diameter of the master in the measurement field is
displayed (sampling time 1 second) with the resolution of 0.0001 mm (1/10 µm).
Place the known diameter master in the measurement field so that it remains still and centred in the
measurement field: the diameter value measured by the instrument will appear on the display.
Use the
arrow keys
(
F2
and
F3
) to modify the value viewed on the display until you reach the
known diameter value of the sample master.
Every time you press the key
(
F3
) the value increases by 0.0001 mm (1/10 µm).
Every time you press the key
(F2) the value decreases by 0.0001 mm (1/10 µm).
Every time you press the
arrow keys
(
F2
and
F3
) the instrument beeps. If you keep the keys
pressed, the increase/decrease will be continuous.
Once the desired value is viewed on the display, press
Enter
(
F1
): if calibration was successful, the
instrument will emit a long beep. The offset value will appear in the window next to the entry
Offset
.
To exit without saving the changed Offset value, press
Exit
(
F4
)
Attention: during calibration, the known diameter master must be positioned so that it
remains still and centered in the measurement field.
Attention: the sample master must remain in the measurement field during the entire
calibration procedure. If the master exits the measurement field during calibration, the
procedure will not be successful: when you press Enter (F1) the instrument will not emit a
long beep and the offset value will not be modified.
FACTORY
This is to restore the factory calibration by resetting the previously set offset value.
Select the entry by pressing
Enter
(
F1
) to access the selection menu of the following options:
Cancel
:
this cancels the operation, the offset value set is not cancelled and you go back to the
previous window
Confirm
: you proceed with the factory calibration and the currently set offset value is reset. The
instrument emits a long beep to confirm the operation and goes back to the previous
window.
