The Chatillon CSD Series Dynamometers are diagnostic devices used for quantitatively evaluating muscle strength.

The Chatillon CSD Series Dynamometers are diagnostic devices used for quantitatively evaluating muscle strength. These instruments are powered by a rechargeable battery (7.5 Vdc) which supplies a regulated 5 Vdc excitation voltage to a strain gage load cell. The output from the load cell passes through an A/D converter which produces a digital signal that is directly proportional to the applied force. This signal is then sent to a microprocessor which converts the signal to a force value that is stored in memory and/or displayed on an LCD. This basic design has been used for many years in industrial force measuring instruments that have found their way into hospitals, clinics and other similar facilities through industrial distributors. The instrument submitted herewith is a repackaged version of the industrial instrument with attachments that are more appropriate for performing manual muscle testing.
