When you are preparing to do a Density Test it will be necessary to fill the beaker
with liquid. The choice of which liquid will be left for the user to decide, however
some solvents may not be compatible with the Polycarbonate of the beaker or
ABS of the Sample Pan. Test a small sample of the liquid on the plastics before
filling the beaker if unsure.
To fill the Beaker with liquid lift the Chamber lid, or unlock and remove the
Density Chamber from it's support and pour through a funneled container. The
beaker should be filled no higher than the maximum filling mark and needs to
cover the metal part of the Temperature Sensor cable. If the Chamber is
removed refit the Chamber once finished as described earlier. Care should be
taken to not spill any liquid onto or inside the balance as damage may occur
which is not covered under the normal warranty terms.
To fill the beaker whilst it is away from the balance it will be necessary to remove
the Temperature Sensor and clip from the beaker which then allows it to be
removed from the support. The cable will need to be pulled gently upwards from
below the Temperature Sensor clip to allow easy removal of the clip. When re-
fitting the Temperature Sensor and clip follow the previous instructions ensuring
the cable is pulled down into a tight position and lifted away from the Chamber.
If water is used a few drops of liquid detergent may be added to the water to
improve the wetting ability and avoid trapped bubbles of air on the sample being
tested.
Stir well to distribute the soap evenly.
When removing samples use a towel to dry the samples immediately so the
water does not splash onto the balance
