6-3. Cautions on installation
When an object other than measured object is installed close to the electrostatic sensor, the
sensor output can be different from actual value due to the effect of charged potential of installed
object. Don’t place the object, which is not to be measured, or the sensor head cable around the
sensor detection hole. Brackets to fix the sensor shall not be covered with insulation layer such
as paint or surface treatment.
When installing the object around the electrostatic sensor, keep the object which is not to be
measured apart more than minimum installation interval in the table below.

Electrostatic sensor is affected by electric field or electromagnetic field due to its operation
principle.
If the cable, transmitter, or wireless equipment that carries large amount of current is present by
the sensor head, correct detection of static electricity could be disabled.
Avoid using the sensor where those components are present.
