AM32 MULTIPLEXER
7
The example in Section 7.3 is an example of a
multiple loop instruction sequence where each
loop is terminated with a P95 instruction The
multiplexer is not reset between loops. Section
7.3 demonstrates measurement of two
dissimilar sensor types (i.e. soil moisture blocks
and thermocouples).
5.0 SENSOR HOOK-UP &
MEASUREMENT EXAMPLES
This section covers sensor-AM32 connections
as well as AM32-datalogger measurement
connections. The following are examples only
and should not be construed as the only way to
make a particular measurement. See the
Measurement Section of your datalogger
manual for more information on the basic
measurements.
5.1 SINGLE-ENDED ANALOG MEASUREMENTS
Sensor to Multiplexer wiring
- One single-
ended analog signal can be connected to each
AM32 input channel for measurement.
Multiplexer to Datalogger wiring - Signal lines
from the COM terminals are input into one
single-ended channel and ground. Signal
grounds are tied to analog ground (AG) for the
CR10(X) and datalogger ground for the 21X
and CR7. Up to 32 single-ended
measurements can be made using one single-
ended datalogger channel.
