Over range Indication
If the weight applied to the weighing platform exceeds the maximum capacity of the DS-220 (100
kg), a single “1” will be shown on the left side of the display. To prevent damage to the DS-220,
immediately remove the weight from the platform.
Measuring Weight
Measuring Weight with the DS-220 is straight forward:
1. Set up the DS-220 as described in the QUICK START Setup section above.
2. Select WEIGHT using .
3. Select the desired units of measure using .
4. Use as necessary, and apply (or remove) weight to be measured.
Measuring Volume
The DS-220 calculates liquid volume based upon the weight of the liquid being measured. In
order for this calculation to be accurate, the specific gravity of the liquid must be known.
Specific Gravity is defined as the ratio of the density of the liquid to the density of water. Pure
water has a specific gravity of 1.000. Other liquids have a specific gravity other than 1.000. Refer
to the appendix for a list of common liquids and their corresponding specific gravities.
There are two modes of Volume measurement. The first mode, when only the VOLUME indicator
shows on the display, assumes a specific gravity of 1.000 (water). In the second mode, when
SPECIFIC GRAVITY, in addition to VOLUME, shows on the display, the specific gravity is
adjustable, allowing accurate volume measurement of any liquid. To measure liquid volume,
perform the following steps:
1. Setup the DS-220 as described in the QUICK START Setup section above.
2. Select VOLUME (if measuring water) or VOLUME SPECIFIC GRAVITY (if measuring other
than water) using .
3. Select the desired units using .
4. If using specific gravity, adjust the specific gravity shown on the ALTERNATE NUMERIC
DISPLAY by pressing and/or holding or . The specific gravity can be set faster by
pressing .
5. Proceed to measure the volume as described in the QUICK START Basic Operation section
above.
NOTE: The range of specific gravity adjustment is from 0.500 to 2.000.
