DS-220 User’s Guide Quick Start To operate the DS-220 as a basic weigh scale, perform the following steps: Setup 1. Unpack the scale as described in the “Unpacking the DS-220” section below. 2. Install the batteries into the control box as described in the “Battery Installation” section below. 3. Place the Weighing Platform on a firm, level surface. 4. Turn the DS-220 on by pressing . 5. If desired, turn on the backlight by momentarily pressing 6. Select the weigh mode by repeatedly pressing follows: .
DS-220 User’s Guide Basic Operation 1. If using a container to hold the objects or liquids being measured or counted, place it empty on the center of the platform. 2. Press to “zero-out” the scale. The display will read zero. 3. Place the material to measure in the container or on the center of the platform. 4. Read the weight, volume, or number of items on the display. 5. A positive number indicates the applied weight is greater than the zero value.
DS-220 User’s Guide Battery Installation & Replacement 1. Remove the battery cover from the rear of the control box by compressing tab at the base of the battery cover. 2. If necessary, remove old set of batteries. 3. Insert 4 ‘AAA’ Alkaline batteries. Replace battery cover by aligning tabs and snapping back into place.

DS-220 User’s Guide 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 .
DS-220 User’s Guide 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.
DS-220 User’s Guide Counting The DS-220 can count items of equal weight. In order to count accurately, the scale must be “trained” to recognize the weight of the items being counted. To train the DS-220 for counting, perform the following steps: 1. Set up the DS-220 in counting mode as described in the Quick Start Setup section. 2. Remove all objects from the weighing platform. 3. If a bin is going to be used to hold the items being counted, place the empty bin on the center of the platform. 4. Press .

Wait 5 seconds for the load to stabilize, then press and the SET TANK indicator will turn off. . This completes the training process, 6. From this point forward, the Alternate Numeric Display will show the percent of material remaining in the container from 0% to 100%. NOTE: The 100% weight must be larger than the 0% weight by at least 200g.
DS-220 User’s Guide Battery Level Indicator The battery level indicator shows the relative strength of the batteries. Full power is indicated by four bars. As the batteries are depleted, the number of bars displayed decreases, until no bars are left. At this point, it is necessary to replace the batteries (refer to the Battery Installation section above).
DS-220 User’s Guide Restoring Factory Calibration If you make a mistake recalibrating the DS-220, you can always restore the factory calibration (and factory defaults) of the scale.
