1.
Remove the weighing pan and breeze break from
the balance.
2.
Place the density pan stand on the balance.
3.
Place one small balance weight and one large
balance weight on the density pan stand.
4.
Place the beaker stand so that it does not touch
the density pan stand.
5.
Attach the thermometer clamp to the beaker
and
insert
thermometer clamp.
6.
Pour a liquid with a known density (such as
distilled water) into the beaker and place the
beaker on the beaker stand.
7.
Place the density pan on the density pan stand.
8.
Adjust the amount of the liquid so that the sample,
when placed on the lower pan (in the liquid), is about
10 mm below the surface of the liquid.
9.
When the value displayed on the balance is stable,
press the RE-ZERO key to set the displayed value
to zero.

10.
When
on the balance, perform a zero calibration.
Now the balance is ready for density measurement.
