15. DENSITY MEASUREMENT
The GX series balance is equipped with a density mode. It calculates the density of a solid using the
weight of a sample in air and the weight in liquid.
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.
Two ways to set the density of a liquid are available:
by entering the water temperature or by entering the density directly.
The density determination kit (GX-13) is available as an option for GX-200/300/400/600/800/1000.
Formula to obtain the density
The density can be obtained by the following formula.
Where
A
: Density of a sample
A: Weight value of a sample in air
B: Weight value of a sample in liquid
B
: Density of a liquid
Changing the function table
(1) Selecting the density mode
The density mode is available as one of the weighing units. To use the mode, select it in the
function table. For details, refer to “5-2 Storing Units”.
(2) Selecting a way to set the density of a liquid
Select the liquid density input method from the function table below. The function table is
available only when the density mode is selected.

Setting the density of a liquid
1. Press the MODE key as necessary to select the density mode. When the processing indicator
blinks with the unit “g” displayed, it indicates that the density mode is selected.
2. In the density mode, press and hold the MODE key to enter the mode to set the liquid density.
Note
In the normal weighing mode, the same procedure will activate the automatic response
adjustment. This function is not available in the density mode.
Entering the water temperature (
ldin 0
)
In the density mode, press and hold the MODE key until the water temperature currently set (unit:
°
C,
factory setting : 25
°
C) is displayed. Use the following keys to change the value.
RE-ZERO key
To increase the temperature by one degree. (0-99)
MODE key
To decrease the temperature by one degree. (0-99)
PRINT key
To store the change, display
end
and return to the density mode.
CAL key
To cancel the change and return to the density mode.
