• Install a 250ml beaker (not supplied) as shown when

using the density kit and suspend a precision cali-

brated thermometer 0° C to 30° C on the edge of the

beaker.

• Suspend the Weigh Below Hook from the Bracket into

the beaker.

• Fill the beaker with auxiliary liquid (liquid of known

' usually distilled water or ethanol). Insure

that the liquid will cover the sample by at least 1 cm
after immersion.

• Ensure that no air bubbles adhere to the immersed

part of the Weigh Below Hook. Remove air bubbles
by moving the Weigh Below Hook or by means of a
fine brush.

• Close the draft shield doors and tare the balance.

• Open the draft shield of the balance.
