8.10 Tin on brass
Select „M“ for optional metal selection. For Sn = 12 µm,
e.g., it is recommended to adjust the instrument as
follows:
De-plating speed: 5...6 µm/min
Sensitivity:
2,5
Calibration:
1,7-1,75
Solution:
E9
Note:
The instrument settings under 8.9 and 8.10 are general
recommendations and may vary according to the indi-
vidual gauges. For that reason, calibration must be car-
ried out for each GalvanoTest 3000 gauge individually.
8.11 Thick coatings
When measuring thick coatings, the instrument may
switch of prematurely i.e. before the coating has been
removed completely. In such cases “0.00” will be shown
on display and no reading will be stored.
8.8 Nickel on copper on steel
If the instrument does not switch off when using E14
solution for nickel coatings on copper (Cu < 2 µm), it is
recommended to use E4 solution. Please note that in
this case, the instrument must be calibrated accordingly
and that E4 solution removes both layers in one
measuring process.
8.9 Copper on zinc
Select „M“ for optional metal selection. It is recommended
to adjust the instrument as follows:
De-plating speed: 3...4 µm/min.
Sensitivity:
1,0
Calibration factor: 2-2,1
Solution:
E12
