1. Unpacking and Inspection

7/16” wrenchflats Manufacturers of transducer tube may be installed in any orientation. However, ifcondensation is likely to occur, then port should be orientateddownward.When installing 1/8” NPT style transducer tube, use the 7/16” wrenchflats as shown.Attach cable. With the suction chamber at atmosphere, turn on the power supply suppliers(typically +24 VDC. Gauge is now reading pressure. The pressurein Torr as read by channel 1 is given by, P = 100 x V where V is thevoltage between pins 5 and 6.For best accuracy, the gauge should now be zeroed. Pump thevacuum system down to low (10 Transducer OBE Module D-connector
-6 Torr) pressure if possible. Ideallythe gauge should be operated in this condition for one hour.Place the HPM-2002-OBE in the “CAL” mode by using the “SELECT”button. Using a small flat head screwdriving, rotate the “ADJUST”supplier of rotary encoder until the unit flashes between “0.0” and “-0.0”.Return to the “RUN” mode by using the “SELECT” button. *Similary the pressure in mTorr as read by channel 2 is given byP = 100 x V where V is the voltage between pins 7 and 6. Unpack and inspect all items for any obvious signs of damage due to shipment. Immediately advise the carrier who delivered the shipment if any damage is suspected.
