Page 3: Description And Principle Of Operation
This result is an output voltage which is linearized, temperature compensated, scaled and amplified. The voltage is displayed on the DIGIVAC 760 as 0 to 760 Torr or 0 to 1013 mbar. The instrument features large, bright LEDs visible from a distance with a hard, vinyl clad metal enclosure. The straight forward design yields a low power instrument, that is simple to build and simple to operate. -
Page 4: Operation
The RS232 connection can be made to a PLC or computer via a male DB9 cable connection to the female jack on the DIGIVAC. The DIGIVAC acts as a DCE, so a straight serial connection is appropriate. Please use the supplied 5V AC adapter with your instrument. This adapter provides clean short protected power to protect and insure accuracy of the internal circuitry. - Page 5 Your 2L760 should be set by default with the IP address 192.168.0.200.

Page 8: Notes On Calibration
8.0 UNDERSTANDING TORR. The 2L760 and many similar instruments are calibrated in microns or "millitorr." Microns are not really a measure of vacuum at all, but rather of absolute pressure. It will be recalled that the pressure of the atmosphere is 14.696 or approximately 14.7 pounds per square inch at sea level. -
