Example:
If you want to measure Cu 50µm at a de-plating speed
of 3,14µm/min, the instrument switches off after remov-
ing a coating thickness of 31,4µm as maximum de-plat-
ing time is 10 minutes:
10 x 3,14µm = 31,4µm
In such cases we recommend to carry out measurement
in two steps:
-
Switch off the instrument manually before
automatic switch-off.
-
The reading will be stored automatically.
-
Restart measurement. As soon as the gauge
switches off automatically, both values can be
added to give you the total thickness.
9. Calibration
Accurate calibration is most important for successful
measurement. Previous calibration values can be
overwritten by new ones. Stored readings remain
unchanged. New measurement series, however, cannot
be stored until previous readings in the statistics have
been deleted (see section 12.5 „Deleting a measuring
series incl. statistics“).
9.1 Calibrating by means of a coating
thickness standards
-
Take measurement on the coating thickness
standard.
-
Press SET-key for positioning the cursor to CAL.
A reading is shown with the corresponding unit
(microns or mils) shown on the alphanumerical
display.
-
Use the ARROW-keys for setting the thickness
as indicated on the calibration standard.
Continuous pressing of ARROW-keys supports
quick function. Your setting will be valid without
the need of being confirmed.
-
If MiniPrint 4100 is connected and switched on,
the message *Cancel* will be prined after pressing
the ARROW-key.
-
The following measurements will be carried out
on the basis of your calibration selection.
-
For checking purpose, take another measurement
on your calibration standard.
