• Press
Enter
button.
• Using the arrow buttons, select CHANGE MODE.
• Press

arrow button and select SOLID.
• Press
Enter
button.
• Press
or
arrow button and select H2O.
NOTE:
At this point you could also select either ethanol or a
different auxiliary liquid. When a different auxiliary liquid is
selected, you must enter its density and name it for the library.
• Place a beaker underneath the balance (not supplied) and
suspend a precision calibrated thermometer 0 °C to 30 °C
on the edge of the beaker.
• Tare the balance.
• Press
Enter
button, ENTER TEMPERATURE is displayed.
• Using the arrow buttons, enter the temperature of the liquid
in the beaker.
• Press
Enter
button, the display DENSITY SOLID requests
item to weighed, press the
#
#

button.
• Weigh the solid (weight
A ) by pressing the
Enter
button.
The display now requests the weight in liquid.
• Suspend the sample from the Weigh Below Hook into the
beaker. Use a fine wire or thread.
• Fill the beaker with auxiliary liquid (liquid of known density
Q
0
' 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 supporting wire. Remove air bubbles by moving the
wire or by means of a fine brush.
• Weigh the solid (buoyancy
P ) by pressing the
Enter
button.
The display indicates the density in grams/ cc.
• Successive samples may be taken by pressing
Enter
button
with SET highlighted on the bottom of the display screen.
