Omega Engineering DAQ-12 user manual Recommended Input Ranges and Gain Settings

Page 12

Table 2-1 details the available gain settings and resulting input ranges for the various input configurations. Note that the 'gain byte' field in Table 2-1 is the value written to the DAQ-12's gain control register. (* indicates unipolar mode not available with gain of ½ ).
