The previous DMT myograph models such as the DMT310A, 410A, 510A, 610M and DMT 800MS had a voltage output of 1V.
However, the analog voltage output of the DMT 620M/720MO/820MS interfaces (available February 2010) is 2.5V. Thus, please set the range in LabChart to 5V if using these systems.
As of July 14 2017, ADInstruments no longer sells or supports any DMT products (unless previously purchased under tender contract). Instead, please contact DMT direct.
