Circuitry
GND shall be grounded to earthing resistance of 100 ohms or less. Exclusive power supply is
recommended for the power to actuate the sensor. If other components are connected to this
power supply when static electricity is discharged to the sensor head or noise interrupt GND,
connected component could malfunction or be damaged.
When the cable for connecting external equipment is cut in short length, do not connect the
shield line(Shield line is common with amplifier case. Frame ground shall be prepared with the
amplifier case side).
