[Setup] is pressed becomes the active mode. Auto starts dynamic weighing test as soon
as weight exceeding a set threshold is loaded on the pan. Manual requires the user to load
the pan and then press a button before weighing commences
10.4.5 Net / Total

Press [Mode] in normal weighing using [Up] and [Down] keys; select ‘’ Net/Tot’’
press [Setup] key to enter this function.

Put a weight on the pan; when stable symbol displayed press [Setup] key, this will
store the weight value; press [  0/T  ] key to zero.

You can keep adding weights and storing the new total weight using the above steps.

Pressing the [Mode] key shows the total recorded weight, pressing [Esc] key returns
to normal weighing.
10.4.6 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.
10.4.6.1 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.
Steps:
Press [Mode] and then [Up] and [Down] keys until “ Density Solid ” or “ Density Liquid ” symbol is
displayed and then press [Setup] to enter chosen density mode.
When “
Density Solid
” is selected, the type of liquid used for the test must be selected:
Press [Up] or [Down] to select the liquid – water (display  ethanol 
or other 
For Water and Ethanol :
The density will be calculated based on the liquid temperature. A prompt 
or  shortly followed by a numeric value e.g 
.
 and the “ °C ” symbol at
the top left of the display will appear. Measure and enter the temperature of the fluid
using the keypad numeric entry method (see section 8.1).
or
For Other :
The liquid density value must be accurately known, and entered manually. A value
will appear on screen e.g

.
 Enter the known density (g/cc) using the
numeric entry method (see section 8.1). Value must be in the range 0.5 ≤ 2.0 . If a
value outside this range is selected then it will not be accepted and  or
 will be displayed followed by return to the time entry screen again.
