Measurement Computing CIO-DAS-TEMP - Manual (Page 5)

1 INTRODUCTION
The CIO-DAS-TEMP is a temperature measurement board desig ned for use with the A D592
semiconductor temperature sensor. Since the AD592 is a current output dev ice, the on-board signal
conditioning is optimized for that sensor. A voltage-to-frequency converter translates the signal from the
sensor into a v alue proportional to tem perature. Functions in the Univ ersal Library convert that
proportional value into a temperature reading on which you can base a control system, or simply log for
later analysis.
The AD592 semiconductor temperature sensor is ideally suited for measurements in the ambient range. If
you are designing an HVAC system, or need to monitor the efficiency of an existing system, the
CIO-DAS-TEMP provides the best value and accuracy in the ambient range. More accurate than
thermocouples and less expensive than RTDs, the AD592 sensor is available through general distribution
or from Measurement Computing Corp. as an individual part or in a stainless steel probe.
Custom Ranges
The CIO-DAS-TEMP is a current input board with a fixed range of 0 to 500
µAmps. The front end may
be customized to allow up to 0 to 20 mA. T he CIO-DAS-TEMP provides up to a full 16 bits of
resolution and will easily reject line noise. If you have a current measurement application and want a
precisely matched front end, please call our technical support and explain your needs to us.
2 INSTALLATION
2.1 SOFTWARE
There is a bank of switches to set before installing the board in your computer. By far the simplest way to
configure your board is to use the
Insta Cal TM program provided as part of y our software pack age.
Insta Cal TM will show you all available options, how to configure the switches to match your application
requirements, and will create a configuration file that your application software (and the Universal
Library) will refer to so the software you use w ill automatically know the exact configuration of the
board.
Please refer to the Software Installation Manual regarding the installation and operation of InstaCal TM .
The following hard copy information is provided as a matter of completeness, and will allow you to set
the hardware configuration of the board if y ou do not have immediate access to InstaCal
TM and/or your
computer.
