2. Installation

This section is designed to assist in getting a new pressure gauge into operation as quickly and easily as possible. Please read the following instructions thoroughly before installing the instrument.

2.1. Receiving Inspection

Carefully unpack the Hastings Model HPM-2002-OBE Instrument (part # HPM-2002-OBE), and

transducer tube (part #HPM 2002s-xx). 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.

Compare each component shipped against the packing list. Ensure that all parts are present (i.e. transducer, electronics module, hardware, etc.). Optional equipment or accessories will be listed separately on the packing list.

2.2.Quick Start

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.

Wire the 15-pin “D” connector according to cable pinout (see Table below) using 24 AWG or other suitable wire.

Using a unipolar DC Power Supply, set the desired operating voltage within the range of 12 VDC to 30 VDC.

Connect the HPM-2002-OBE module to the HPM-2002s transducer tube.

Note that the connector is keyed.

A finger tight connection is all that is required for adequate operation.

Transducer tube may be installed in any orientation. However, if condensation is likely to occur, then the tube port should be orientated downward.

When installing 1/8” NPT style transducer tube, use the 7/16” wrench flats.

Attach cable.

With the vacuum chamber at atmosphere, turn on the power supply (typically +24 VDC. Gauge is now reading pressure.

For best accuracy, the gauge should now be zeroed. Pump the vacuum system down to low (10-6Torr) pressure if possible. Ideally the gauge should be operated in this condition for one hour before setting the “Zero”.

To set the “Zero”, 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

2.3.Transducer Installation

The transducer tube may be installed in any orientation. Although the transducer tube is rugged and will perform well in many harsh environments, the tube should be installed in a clean and careful manner. The tube is configured with the vacuum fitting requested. If your vacuum environment is highly contaminated or has unique fitting requirements, a Hastings filter or special adapter may be needed. Please contact the Hastings Instruments Sales Department for assistance in your system configuration.
