Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
Psychrometer measurement requires the S3497X Software that is contained on a special CR7 Measurement and Control System PROM (the PROM is then inserted in the CR700X Control Module). Instruction 25 controls both the cooling/heating process and thermocouple measurement.
Up to five psychrometers can be cooled/heated with one A3497; all connected psychrometers are cooled simultaneously. The excitation for each A3497 is sourced from one excitation channel on a CR725 Excitation Card; up to eight A3497s can be connected to each 725. The reference temperature measurement and the thermocouple measurements are made by the CR723T Card; up to 14 psychrometers can be measured with each CR723 Card.
