Chapter 1 Installation
Warm-up is necessary to collect accurate data.
3. Connect the tester (voltmeter) across the Input Signal and Input Common
terminals on the measurement module base and read the voltage.
4.
Refer to Standard Static Characteristics on page 41 to make sure that the
desired set gap voltage is indicate
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.
IMPORTANT Data indicated in Standard Static Characteristics (on page 41) are measured
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.
