2.10.5 Liquid Specific Gravity Measurement
Liquid specific gravity measurement refers to the measurement of the weight of a reference
solid of a known volume in air and in the sample liquid. Specific gravity for the liquid is
calculated from these two values of.
The display unit for liquid specific gravity is "d." The data output unit is DL.
1) Set Menu Map item [61].
Note:
Enter the value for the volume (cm
3
) of the reference weight.
2) Attach the optional weighing hook to the bottom of the balance, attach the
hanging pan, and then immerse the hanging pan in a tank containing the
sample liquid.
3) Press the key until "d" is displayed.
4) Press the key.
5) Load the reference weight on the pan of the balance.
6) After the stability symbol is illuminated, press the key.
may be displayed but does not indicate a malfunction.
7) Load the reference weight on the hanging pan and immerse it in the sample
liquid. The specific gravity of the sample liquid is displayed.
8) Repeat steps 4 through 7 for each additional sample.
Note:
•
Up to four decimal places are displayed for specific gravity. Since it may not be
possible to stabilize the balance using all 4 places, 1d/10d switching is possible.
•
When loading the sample on the pan, immerse the entire sample in the liquid.
•
T release the ▼ d, d or units, set the value to zero.
•
When the optional Specific Gravity kit is used, refer to the Instructional Manual
of the Specific Gravity kit for the procedure.
