Table 3 . Analog output with displayed pressure values
Pressure as a function of the analog output can be approximated by
P = 0.01 * 10
2 V
where
V is the analog output in volts and P is pressure in mTorr. For example, if V is equal to
3.50 V, P is approximately 100 Torr.
Pressure values are converted from torr to millibar or Pascal
units.
