Determining Specific Gravity
It is possible to determine the specific gravity of a liquid if you already know its volume. Using a
graduated container appropriate for the liquid in question, perform the following steps:
1. Ensure the DS-220 is in VOLUME SPECIFIC GRAVITY MODE (refer to the Quick Start
section).
2. Place the empty graduated container to the center of the platform.
3. Press to “zero-out” the weight of the container. The display will read zero.
4. Fill the container to the mark indicating the volume of the liquid in the container.
6. Adjust the specific gravity shown on the ALTERNATE NUMERIC DISPLAY by pressing
and/or holding the or until the displayed volume equals the known volume of liquid
in the container. The specific gravity can be changed faster by pressing .
5. Read the specific gravity of the liquid on the ALTERNATE NUMERIC DISPLAY.
NOTE: The accuracy of the Specific Gravity calculation will be dependent upon the volume
measured. Greater volumes will result in better accuracy.
USE CARE WHEN MEASURING LIQUIDS WITH THE DS-220. DO NOT SPILL LIQUIDS
ONTO THE PLATFORM OR CONTROL BOX, AS THIS CAN DAMAGE THE SCALE.
ALWAYS USE EXTREME CARE WHEN HANDLING FLAMMABLE MATERIALS. IN
ADDITION, OBSERVE PRECAUTIONS WHEN HANDLING COROSSIVE OR TOXIC
MATERIALS, INCLUDING HOUSEHOLD OR INDUSTRIAL CHEMICALS. USE PROTECTIVE
CLOTHING, EYEWARE, AND GLOVES AS REQUIRED.
