1. Unpacking and Inspection
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.
Transducer
OBE Module
D-connector
4. Gauge Installation
Transducer tube may be installed in any orientation. However, if
condensation is likely to occur, then port should be orientated
downward.
When installing 1/8” NPT style transducer tube, use the 7/16” wrench
flats as shown.
Attach cable.
With the vacuum chamber at atmosphere, turn on the power supply
(typically +24 VDC. Gauge is now reading pressure. The pressure
in Torr as read by channel 1 is given by, P = 100 x V where V is the
voltage between pins 5 and 6.
For best accuracy, the gauge should now be zeroed. Pump the
vacuum system down to low (10-6 Torr) pressure if possible. Ideally
the 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 screwdriver, rotate the “ADJUST”
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 by
P = 100 x V where V is the voltage between pins 7 and 6.

2. Cable Connections (0-10 output) 3. OBE Module Installation
Wire the 15-pin “D” connector according with the wiring table using
24AWG or other suitable wire.
Using a unipolar DC power supply, set the desired operating voltage
within the range of 11.5 VDC to 30 VDC.

(suggested) Description
Connect the OBE module to the HPM-2002 sensor tube.
Note that the connector is keyed.
A finger tight connection is all that is required for adequate operation.
