5.2 Determination of potential
The potential (voltage level) of the measured surface area can be determined from the field
intensity measuring value.
The following relationship applies:
Field intensity (in kV/m) x measuring distance (in m) = Potential (in kV )
The measuring distance for the Statometer II is: 30 mm = 0,03 m
Example: Field intensity determined = 12 kV/m
Potential (in kV) = 12 kV/m x 0,03 m = 0.36 kV = 360 V
5.3 Determination of charge density
The surface charge density is proportional to the normal component of the electric field. The
connection is made using the absolute permittivity
0
= 8,86 x 10 -12 As/Vm.
The charge density therefore results from the equation
Charge density = field intensity x absolute permittivity

For the above example:
 = 12 kV/m x 8,86 x 10 -12 As/Vm = 106,32 x 10 -9 As/m 2
6 Remedy of defects
In case of malfunction in connection with the Statometer II, first check for correct installation and
fusing (for replacement, refer to Section 7.2). If this does not solve the problem, please return the
Statometer II and the measuring head to HAUG for a check-up.
