Configure the XM-124 Standard Dynamic Measurement Module Chapter 2
In Normal mode, the module behaves as a two channel differential unit with
the probes mounted on the casing and measuring the shaft position relative to
the casing. Positioning of probes is critical to be sure that valid shaft movement
cannot at any time damage the probes. Selection of probe type and range is
important. The static gaps of the probes are automatically subtracted from the
measurement so that the system can measure small movements relative to the
total gaps.
When using this mode, the module uses straight targets, angled targets, or
mixed target types, as shown in
Figure 38 .

The XM-124 provides monitoring facilities only for axial (thrust)
measurements.
