19.Density Measurement
The balance is equipped with a density mode. It calculates the density of a solid using the mass value
of a sample in air and the mass value in liquid.
For measurement, it use of the option GXA-13 specific gravity measurement kit is remommended.
Note
□
The density mode was not selected for use when the balance was shipped from the factory. To use
the mode, change the function table and activate the density mode " ". Refer to "4.Weighing Units".
□
Minimum display is fixed while density mode.
Formula to obtain the density
1. Density of solid
It can be obtained from the weight of the sample in air, the weight in the liquid, and the density of
the liquid.
：
Density of a sample
A
: Mass value of a sample in air
0
：
Density of a liquid
B
: Mass value of a sample in liquid
2. Density of liquid
Weight in air, weight in liquid and volume of float can be obtained using a float of a known.
：
Density of a sample
A:
Mass value of a sample in air
Ｖ
：
Volume of float
B
: Mass value of a sample in liquid

Prior to measurement: Changing the function table
Prior to measurement, change the function table as follows:
1. Register the density mode.
Density mode cannot be used at the factory setting.
Please refer to "10.Function Table, Unit registration" and register the gravimeter mode ( ).
Density mode is selected as one of the units with the MODE key.
2.
Select whether the object to be measured is solid or liquid. (Function setting ,
)
3.
In the case of solid density measurement, select a method of inputting the density of liquid
(
function setting
,
)
Density of liquid can be set by water temperature input or direct input of density, or input by the following
function setting can be selected.
4. To start the measurement, display the weighing display.
Press the MODE key to display the specific gravity measurement display.(Refer to the following page "Setting
procedure,2,3")
Note
□
The following density function ( ) is not displayed in the function settings unless density
mode is enabled. First, perform the "Register the density mode" operation with the unit setting
( ) of the function setting. When density mode is activated, " " appears next to
" ". For how to change the function setting, refer to "10. Function table".
