OWL Temperature Data Logger (Internal Sensor)
Features
The OWL Temperature Data Logger with the Internal Sensor offers temperature recording in a small,
water-resistant enclosure. In addition to its rugged construction, the logger can be setup to record a
wide range of temperatures, all configurable by a few, easy keystrokes.
2.1
Description
The Internal Sensor Temperature Logger uses an on-board thermistor to record changes in
temperature. The model available is the OWL-100 which operates
-40° to 85°C (-40° to 185°F).
2.2
Setup and Use
The steps required to configure the OWL Temperature Logger are as follows:
1. Run TrendReader Software and communicate with the logger from the OWL Main menu by pointing
the flashing wand at the logger's optical port. Once the Status menu is displayed select the Setup
option.
2. Make sure the Internal sensor equation is chosen. Then select a range that best fits the expected
data (see Appendix A for a list).
Selecting the range
TrendReader enables you choose the size of a range and to choose a midpoint for a range. The
advantages of taking these two steps are:
1. The smaller the size of a range the higher the resolution of the readings.
2. The readings closest to the midpoint of a temperature range are higher in resolution than those at
each end of the range.
The first number (on the left above the slider bar) is the midpoint of the range you want to
measure, and the second number (on the right) is the size of that range.
