The instrument is ready for product testing as received from the factory, but several checks should be made in order to assure that none of the fittings leak when testing is performed.

1. Apply a small amount of "O" ring lubricant to the temperature sensor stem and work it up and down to lubricate the "O" ring (6008). "O" ring lubricant may be purchased from Zahm and Nagel Co.
2. Pressurize the instrument and apply a soapy water solution to all fittings. The formation of bubbles will indicate any leakage, and the condition can then be corrected. Do not apply solution directly to the temperature sensor, computer housing, or its electrical connections.

1. Turn on the computer (14003) by pressing ENTRY button. The display will show "ON" and then 0.0.
2. Close the snift valve (5077) and depress the lock plates (5026) while pulling up on the cross bar (6019) to a height that will clear the top of the container being tested.
3. Release the lock plates and the cross bar will remain in position until the operator is ready to pierce the container.
4. Raise the temperature sensor (14004) so that it touches the thermometer stop (6006).
5. If testing cans, place upside down on the base pad (5023) and center so that the rubber seal (6013) will line up approximately in the center of the container. Bottles should be tested by piercing through the crown.
6. Depress the lock plates and lower the cross bar to a point where the rubber seal just touches the top of the container.
7. Continue to depress the lock plates and with both hands, push the cross bar rapidly downward until the container is pierced.
8. Release the lock plates. The cross bar will remain locked in place with the rubber seal compressed to prevent leakage at the point of piercing. Be careful not to trip the lock plates after piercing as only a slight upward pressure on the lock plates will release the cross bar and cause the container to lose its pressure.
9. Insert the temperature sensor (14004) to its fullest extent into the container.
10. Hold the instrument by the base (5021) and one of the guide rods (5018). Shake the instrument with a rapid back and forth motion until maximum pressure is displayed on the computer. Set instrument down and press ENTRY key to display volumes of CO₂ gas. Press ENTRY twice to display temperature. Press ENTRY key again to return to pressure mode.
11. After the test has been completed, bleed off pressure slowly through the snift valve. To prevent product from spraying the operator, a piece of plastic tubing should be attached to the hose nipple (5057) of the snift valve and the product drained into a sink or other suitable container.
12. Withdraw the temperature sensor until it touches the thermometer stop (6006).
13. Depress the lock plates and raise the cross bar to clear the container.
14. Close the snift valve and remove the container. The instrument is now ready for the next container to be tested. If no further testing is required, turn the computer off by pressing the ENTRY key for three seconds.
