(4) Place the sample on the pan to measure its
weight in air.
(5) Press the [MODE] key when the display has
stabilized.
(6) The gram mark disappears with the specific gravity measurement mark
remaining illuminating and displaying the specific gravity value.
(The display fluctuates. However, this is not a problem.)
(7) Unload the sample and place the sample
on the underwater pan.
(8) Read the displayed value when the stability
mark illuminates.
- The weight in air has to be more than
100 times the minimum increment to
ensure accurate measurements.
(9) Press the [UNIT] key to revert to the gram display.
- “-OL” is displayed if the calculation results are negative.
- The calculation results can be output by the print command while the results
are being displayed. (Continuous output is not possible during specific gravity
measurement.)
- Return to step (3) by pressing the [MODE] key to continue specific gravity
measurements.
- The specific gravity is calculated using the following equation.
(Weight in Air)
(Weight in Air) – (Weight in Water)
- To stop specific gravity measurement and revert to weight measurement…
