SM-3 THERMAL COMPENSATION UNIT (For use with CGM-5R)
Can be used as a stand alone unit to perform thermal compensation of
Switching between channel A and B is carried out continuously, at rates
of 3.2, 8 and 16 seconds, user selectable.
Both analogue and digital outputs are provided. The unit is primarily
designed to work with the CGM-5R.
Matelect manufactures the SM-3 for switching between two channels of ACPD data and performing the
division of the recorded values automatically. This frees the user from having to attend the experiment
and allows temperature normalisation to be performed during long term tests (where it is more likely to
prove important to do so).
The SM-3 unit switches between the two ACPD channels a preset time (of variable duration). The
switched signal is routed via a standard CGM-5R for processing and then routed back to the SM-3 so
that a highly accurate analogue division can be performed. The resultant normalised signal can then be
recorded by a chart recorder or a PC via Labview drivers for the SM-3.
