for a SCM440 flat target (diameter more than 33 mm). When the target
material or shapes differ, the output characteristics (gain) differ, making it
necessary to compensate with later equipment.
5. If the desired set gap voltage is not attained, readjust the sensor position by
using the following procedure.
a. Loosen the sensor jam nut.
b. Adjust the sensor position so that the desired set gap voltage is
attained.
