The 0-10V output option board, provides voltage outputs proportional to the HPM-2002
pressure reading. The first channel corresponds to the higher-pressure range (0-1024) Torr).
The second channel corrresponds to the lower pressure range (0-1000mTorr). The equation
below gives the output voltage for a given pressure.
V(channel 1) =
P(Torr)
100
V(channel 2) =
P(mTorr)
100
Where:
V (channel 1) is the voltgage between pins 1 and 3,
V (channel 2) is the voltgage between pins 8 and 7.
P is the indicated pressure.
