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.
