3-5 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 equipments
―
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 equipments 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.
