6.2 Mounting
Orient and secure the CS230 in the measurement medium. Keep materials
removed during installation and use that material as backfill.
While installing the CS230, the depth must be referenced between the surface
of the medium and the top of the cross member of the CS230 (shown in
FIGURE 6-1 , Internal Sensor Position #4). If the rigid assembly is not placed
at the correct depth, all measurement depths will be out of place.
Install the external probes horizontally in the measurement medium. This helps
ensure that the most representative measurement is taken at the given depth,
and will not interfere with other nearby measurements.
Orient the signal and power cable of the CS230 towards the datalogger to avoid
loops or strain on the cable. Also use a suitable trench or conduit to protect the
signal and power cable from damage.
Mount the SGB3 inside the datalogger enclosure. Use the supplied hardware to
secure it to the enclosure backplate.
7. Operation
When power is supplied to the CS230 probe, the internal electronics
continuously measures the temperature approximately once per second. The
sensor outputs a running average of 10 consecutive, 1 second readings. The
accuracy specification is based on an average of 10 consecutive readings.
Therefore, after initial power up, a delay of 10 s is recommended to obtain the
best accuracy.
Outputs of both lifetime and user resettable minimum and maximum
temperatures are also available during powered operation from each
temperature point in the CS230. The user resettable minimum and maximum
