3.4 SELECTING THE FILTER PAPER SIZE (MODEL S & T)
The Elcometer 130 can be set to automatically detect the filter paper size in use or
this can be manually selected by the user.
To select the paper size, press Menu/Setup/Filter Paper Size followed by "Full",
"Half" or "Quarter" as required. Selecting "Auto" sets the Elcometer 130 to
automatically detect the filter paper size.
For Half Size Paper, fold the standard paper in half and cut into two along the fold
line. For Quarter Size Paper, fold the standard paper into quarters and cut into
quadrants along the fold lines.
The Elcometer 130 will automatically adjust the reading according to the filter paper
size detected or selected, assuming that the paper is positioned on the
measurement electrodes correctly, and if manually set up, the correct paper size is
used. No manual calculations are required by the user.
3.5 TWO MINUTE TIMER
The wetted filter paper should be left on the surface under test for 2 minutes. The Elcometer 130 has
a built in, optional timer for this purpose. To enable the timer, press Menu/Setup/Timer.
When enabled, the left softkey is labelled "Timer". This softkey is used to start, stop and reset the
timer as required.
Filter paper should be discarded and the sample re-tested if the paper is left on the substrate for more than
3 minutes.
