Next, install the overflow port extension and the drain valve to the Specific
Gravity Tank, The bulkhead fittings are shipped installed into the tank. The
overflow port extension and the drain valve are shipped with teflon thread tape
installed so that you can just thread these items into their respective bulkhead
fittings in the tank, snuggly, to prevent leaks. Refer to product photo for correct
orientation.
The Tank Heater and Circulator are shipped as a single mountable unit. Just
hang the unit onto the tank lip and plug into the appropriate electrical source.
You are now ready to fill the tank with water. Place the tank on the Bench
platform and fill the tank with water. The tank should be filled with a sufficient
amount of water to allow the sample and the bail of the sample container to be
under the water.
Unpack the balance and place on top of the bench so that the weigh-below port
and hook line up with the hole in the top of the bench. Attach the AC cord to
the scale and plug into an appropriate electrical source.
You are now prepared to proceed with a specific gravity determination. Mount
your sample into an appropriate sample container and attach the sample and
container to the scale's weigh-below hook. In most cases, you will need an
accessory hook to attach the sample container to the weigh-below hook.
In most cases this can be as simple as a piece of wire bent into an S-hook
configuration. This hook is not included, since it depends on what type and
size of sample and container are being used.
Once you have a sample and sample container attached to the scale, you can
begin to raise the water tank up to immerse the sample and container into the
water tank. To do this, push down on the silver, crank lock on the back of the
bench. This releases the hand crank, which allows you to begin raising the tank
up. To perform an accurate test, crank the tank up until both the sample and the
bail of sample holder are beneath the water.
Please refer to ASTM C127 for specific test instructions and methods.
