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.

Where:

V (channel 1) is the voltage between pins 1 and 3,

V (channel 2) is the voltage between pins 8 and 7.

P is the indicated pressure.
