Setting up the threshold level in the mode of electric conductivity measurement
-
set up the low value of electric conductivity Min;
-
set up the high value of electric conductivity
Max;
-
set up the trigger logic for threshold level:
-light and sound ALARM shall be triggered, when the measured value of electric conductivity
gets into the middle of a selected range
Min
– Max;
light and sound ALARM shall be triggered, when the measured value of electric conductivity
gets beyond the selected range
Min
– Max.
Measuring Conductivity and Coating Thickness with the PCE-USC 30
Guidelines for successful operation:
-
For accurate measurement of conductivity, the surface coating thickness should be
0.5 mm (0.020 inches).
-
The surface to be measured should be flat, or of the same curvature as the calibration
standards. Where curved surfaces must be measured, additional error may be
introduced.
-
Measurement close to edges and on thin materials may give erroneous results.
-
Check on a known consistent material to establish the influence of these effects.
-
The coating thickness measurement function does not require further calibration, it
should be accurate to better than 10 % of the displayed value on base materials
having a conductivity between approximately 1 % and 100 % IACS.
-
The electric conductivity measurement should be carried out at an ambient and test
object temperature
of 20 ˚ С (68 ˚ F).
