Series 902 Piezo 29
Logarithmic 10
The following graph shows the correlation of logarithmic analog output to
pressure on a 2 to 10 volt scale. This is the output the user will see if the
Analog Output Format – DAC value is LOG10 . To receive analog output for
LOG10, the converter must have a 10 volt scale. The logarithmic output is
P (Torr) = 10
(V/2-2)
.
