Specific gravity mode
In the specific gravity mode, the ratio of the density of a substance to the density of water at its densest
(4 °C) for liquids is calculated.
Specific gravity mode is NOT legal for trade.
Purchase the optional “specific gravity measurement kit” or prepare the equipment
―
a water tank,
hanging string/wire, net/basket for placing the sample, thermometer etc.
―
in accordance with the
samples to be measured.
When purchased with “specific gravity measurement kit”, please refer to the option’s manual.
Procedure to measure the specific gravity:
1.
Prepare the equipment or specific gravity measurement kit.
2.
Input the water temperature or the specific gravity of the reference liquid.
3.
Measure the sample weight in the air.
4.
Compensate the buoyancy acting on the net/basket.
5.
Measure the sample weight in the water/liquid.
6.
The specific gravity of the sample is displayed.
1

Press [Menu] key, then press
[F1]-[F4] keys to go to <11 MODE>
Press [F4] key to change the
setting value.
Press [F1]/[F2] key to select.
<<SPGR>>: specific gravity mode
Press [F4] key to fix.
2
Exit the setting menu.
Press [Menu] key to shift to the
specific gravity mode.
3
Select the reference liquid.
Press [F3]/[F4] key to select the
reference liquid.
<<OTHER>> : liquid other than water
<<H2O>> : water
4
Input the specific gravity of the reference liquid
or the temperature of the water.
<<OTHER>>: Liquid other than water
Numeric value input
(Refer to “2-3-3 Numeric value input”)
Enter the specific gravity of the
reference liquid and press [F4] key
to fix.
<<H2O>>: Water
Numeric value input
(Refer to “2-3-3 Numeric value input”)
Enter the temperature of the water
and press [F4] key to fix.
