1.2 WIN3654 PC Program Installation

Install the WIN3654 program onto the PC by inserting the accompanying CD into your PC and running the SetUp program. Simply follow the on-screen instructions.

When finished, a new Windows Program Group labeled Orbisphere is created containing the software and help files.

1.3 Atmospheric Pressure Equilibrium

As soon as you receive the instrument, it will be necessary to ensure the interior and exterior of the instrument are both at the same atmospheric pressure. It is probable that during shipment these pressures will become different.

To ensure the pressures are equal, simply press the relief valve switch located on the top of the instrument (see Fig 1-1 on page 9) and hold it down for about 5 seconds before releasing.

1.4 Sensor Installation

The TC sensor connects to the instrument base through a 10-pin LEMO connector. A locking pin holds the sensor in place.

Both the membrane-covered TC sensor and the flow chamber are shipped pre-installed on the instrument. It will, however, be necessary to remove the flow chamber when servicing the sensor. For details refer to “Sensor Maintenance” on page 43.
