When
measuring
in
the

is
displayed
as

Electrode Size
Key
The Electrodes Size key is used to enter the thickness of the DUT
, the electrode's size
, and the
eective area coecient of the test xture
. These values are the factors used to calculate the
volume or surface resistivity
.P
arameters are as follows:
Thickness Enters the DUT's thickness
, which is equal to the distance between the
electrodes.Available values are 0.01 mm to 20 mm in 0.1 mm resolution. The
default setting is 2.0 mm.
Rescell Denes the electrode's size and the eective area
coecient of the test xture
.
26mm , 50mm ,and 76mm : Select the electrode diameter ( D
1
) size when
using the 16008B Resistivity Cell. The guard ring diameter size ( D
2
)is
automatically selected according to the D1 value. The eective area
coecient ( B ) is the fraction of the gap width to be added to the diameter of
the electrodes.The B value is usually specied by the standard that you use.
(For example: 1 for ASTM D 257; 0 for JIS K 6911).
