Figure 1-4 Measurement Window Timing
The TMD IV allows you to adjust both the sensitivity of the device to output signals and the location of the
measurement window in the decay time. Signal strength is adjusted by a sensitivity factor; the measurement-
timing window is adjusted based on a material type code factor (see Figure 1-5).

System Components
The TMD IV comes in two configurations, a dual coil system and an under the belt single coil system. The dual
coil TMD IV has a transmitter coil mounted above the belt and a receiver coil mounted under the belt. The
under belt single coil TMD IV is physically different but functionally similar to a standard model. On an under
belt single coil TMD IV, the transmitter and receiver coils are together in a coil assembly mounted under the
belt.
This section describes the major components of a TMD IV system.
