Caution:
EYE PROTECTION MUST BE WORN WHILE OPERATING THIS INSTRUMENT
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 being performed.
- Apply a small
amount of "O" ring lubricant to the dial thermometer stem (6003)
and work it up and down to lubricate the "O" ring (6008).
"O" ring lubricant may be purchased from Zahm & Nagel.
- Pressurize
the instrument and apply a soapy water solution to all fittings.
The formation of bubbles will show any leakage and the condition
can then be corrected. The instrument may also be pressurized
and submersed in an aquarium filled with water and bubbles observed
in this manner.
To
Operate:
- Close the
Whitey TM valve (5056) an depress the lock plates (5026)
while pulling up on the cross bar (6018) to a height that
will clear the top of the container being tested.
- Release the
lock plates and the cross bar will remain in that position until
the operator is ready to pierce the container.
- Raise the
dial thermometer (6003) so that it touches the dial thermometer
stop (6006).
- Place the
can to be tested upside-down on the base pad (5022) and
center so that the rubber seal (6013) will line up approximately
in the center of the container. Bottles could be tested by piercing
through the crown.
- Depress the
lock plates and lower the cross bar to a point where the rubber
seal just touches the top of the container.
- Continue
to depress the lock plates and with both hands push the cross
bar rapidly downwards until the container is pierced.
- 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.
- Hold the
instrument at the bottom of the base with the right hand while
the left hand holds both the guide rod (5017) and the dial
thermometer stop (6006). Shake the instrument with a rapid
back and forth motion until maximum gauge pressure has been obtained.
Record this pressure for future chart calculations of CO2 gas
volumes.
- Insert the
dial thermometer down into the container to its fullest extent
and leave it there until a steady temperature is obtained. The
time required for a steady temperature reading may be thirty seconds
or longer, depending on the temperature of the product being tested.
Record this temperature for future chart calculations of CO2 gas
volumes.
Note: DO not record pressure readings when the dial thermometer
is inserted into the container. This will cause a false pressure
reading and resulting error in the number of volumes of CO2 gas.
- When the
pressure and temperature have been recorded, refer to the correct
pressure/temperature relationship chart. Be sure to refer to the
correct chart when determining the volume of CO2 gas. Charts for
both alcoholic and non-alcoholic beverages accompany the instrument.
- After the
test has been completed bleed off the pressure in the container
by slowly opening the Whitey valve. To prevent the product from
spraying the operator a piece of plastic tubing should be attached
to the hose nipple (5057) of the Whitey valve and the product
drained into a sink or suitable container.
- Withdraw
the dial thermometer until it touches the dial thermometer stop.
- Depress
the lock pates and raise the cross bar to clear the container.
- Close the
Whitey valve and remove the container. The instrument is now ready
for the next container to be tested.
