9.4.5 Density Determination

It is possible to determine the density of solids or liquids using this mode. The
user selects the type of density to be determined and then enters values to be
used by the balance.

The density mode allows the user to use a special Density Kit or use the
below pan weighing facility to perform the necessary weighing.

DENSITY OF SOLIDS

To perform the density of solids test, the user must have a method to
immerse the sample in the chosen liquid. The density of the liquid must be
known or determined from a look-up table.

For water and ethanol the density will be calculated based on the
temperatures entered using the numeric entry method (see section 7.1)

Steps:

• Press [Mode] and then [Up] and [Down] keys to select density

• Press [Enter] to enter Density mode.

• Press the [Up] and [Down] keys to select the solids or Liquid method

when “DENSITY SOLId”” or “DENSITY LIqUId” is displayed

• Press [Enter] to select the solids method

• Press [Up] or [Down] to select the liquid of choice- Water, Ethanol or

Other

• Press [Enter] to select the choice. For water and Ethanol the

temperature will be asked for. Enter the temperature using the numeric
entry method (see section 7.1)

• For the “Other” choice the density will be asked for. Enter the density

(g/cc) using the numeric entry method (see section 7.1)

• Press [Enter] to continue

• The balance will request the weight of the sample in air by displaying

“AIR WEIGHT”. Place the item on the pan or receptacle, if the density
kit is used. Press [Enter] to determine the value

• After completion of the air weighing, the balance will request the weight

in liquid by displaying “LIQUID WT”. Submerge the item in the liquid and
