Chapter 1. Installation
1.9.3.1 M-Series Probes
M-Series probes are primarily used for moisture measurement, but they can be used to measure temperature
as well. If ordered, an optional temperature thermistor is included in the moisture probe and requires an
additional connection.
If the M-Series probe does not have a thermistor, then you may use a two-wire shielded cable with a
bayonet-type connector to connect the probe to the electronics unit. If an optional thermistor is installed, then
use a four-wire shielded cable with a bayonet-type connector to connect the M-Series Probe to the electronics
unit. The M-Series Probe may be located up to 600 m (2000 ft) from the moisture.IQ.
Before making the electrical connections, connect the cable to the probe by inserting the bayonet-type
connector onto the probe and twisting the shell clockwise until it snaps into a locked position (approximately
1/8 of a turn). Wire the probe cable per the wiring diagram in
Figure 12 below. The M-Series terminal block
on the back panel of the moisture.IQ (see Figure 13 on page 18 ) also notes the corresponding color from the
probe cable.

Note:
The label

in Figure 12 above corresponds to the
SH
label on the connector, and these terminals are
used to terminate the cable shield.
