The value XX can be changed to between 0-99 seconds using the keypad numeric entry

method.

To confirm the desired value, press [Setup]

10.4.4

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.

10.4.4.1

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 keypad numeric entry method.

Steps:

Press [Mode] and then [Up] and [Down] keys to select "

Press [Setup] to enter Density mode.

If "Density Solid" was selected, the type of liquid used for the test must be selected.

Press [Up] or [Down] to select the liquid – water (display "wAtEr"), ethanol ("EtHAnOL"),

or other ("OtHEr").

For the "Other" choice the density will be asked for. Enter the density (g/cc) using the

numeric entry method (see section 7.1). The display will show "

Press [Setup] to continue.

The balance will request the weight of the sample in air by displaying "Air wt". Place the

item on the pan, or in receptacle if the density kit is used, and press [Setup]. The weight

will be shown in the last weighing unit selected.

After completion of the air weighing, the balance will request the weight in liquid by

displaying "LIq wt". Submerge the item in the liquid and press [Setup] to start the liquid

weighing. After completion of the liquid weighing, the balance will compute the density of

the sample and display it as "XXXX g/cc".

Remove the item from the pan and press [Mode] to continue with a new sample or press

[0/T] to return to normal weighing.
