STEP OF MEASUREMENT
1 Make sure the display is 0.00g.
2. Pour about 50cc. of liquid sample in a Beaker.

3. Put the Standard Glass Sample used for memorizing data into the Beaker at the preparation

4. Set the Beaker prepared at Step 2. Correctly on the Beaker Line of Beaker Stage

5. Suspend the Hook from the center of the Hanger. Make sure that the lower end of the

Hook is in the liquid sample.
6. Press TARE key to clear the weight of the Hook and make the display 0.00g.
7. Hang the Standard Glass Sample by the lower end of the Hook and suspend it again on Hanger.
• The weight of the Standard Glass Sample in the liquid is displayed.
Make sure that the Standard Glass Sample is completely in the liquid sample without touching the Beaker.
8. Press ENTER key after the stable mark " * " appears. The average mark" — "is vanishing one by one and the
stable mark starts blinking. The machine starts calculating the density of liquid sample based on the
memorized weight of Standard Glass Sample.
9. Measurement result is displayed. SG (specific gravity) is pointed by"<" and the measurement is completed.
The data can be output when using printer.
10. Take out the Hook, Standard Glass Sample and Beaker from the Hanger, then press ENTER key. The
display returns to 0.00g . Liquid Density Measurement is completed.
11. To continue measurement,
a. Wash and dry up the Hook and the Standard Glass Sample well. Use the spare Beaker for the next
measurement. Start again from the Step 1.
b. If changing the liquid sample, change the number of the compensating temperature rate of the liquid as well.
