3 Installation		Model 3020T

Note: If the unit is for vacuum service, see Sample In, above, for gas pressure/flow considerations.

3.6Testing the System

Before plugging the instrument into the power source:

•Check the integrity and accuracy of the gas connections. Make sure there are no leaks.

•Check the integrity and accuracy of the electrical connections. Make sure there are no exposed conductors

•Check that sample pressure is between 3 and 40 psig, according to the requirements of your process.

•Check that the voltage selector switch on the Electrical Connector Panel is in the appropriate position for your power source.

Power up the system, and test it by performing the following operations:

1.Repeat the Self-Diagnostic Test as described in chapter 4, section 4.3.5.
