OWL Temperature Data Logger (External Sensor)
Features
The OWL Temperature Data Logger with the External Sensor offers temperature recording in a small
water-proof* enclosure. The connection between the temperature probe and the logger is water
resistant. There are four temperature probes available that can monitor a wide range of temperatures,
and custom equations can be written to use other probes.

Description
The External Sensor Temperature Logger uses a thermistor type probe to record changes in
temperature. The models available are:
OWL-200
OWL-200

Setup and Use
The steps required to configure the OWL Temperature Logger are as follows:
1. Run TrendReader Software and communicate with the logger by double clicking the com port icon
and pointing the wand at the logger's optical port. Once the Status menu is displayed select the
Setup option.
2. Make sure the External Sensor equation corresponding to the probe attached to the logger is
chosen - see Specifications. Then select a range that best fits the expected data (see Appendix A
