To ensure proper operation of the scale, please read this manual completely. DESCRIPTION The Ohaus DS Series Bench Scales are precision industrial weighing instruments which can be used for almost any application with capacities from 44 to 440 pounds or 20 to 200 kilograms. The scale is designed to provide years of service with virtually no maintenance.
UNPACKING DS Series Bench Scales are shipped with the following components: • • • • • • a platform a power adapter/charger an indicator unit a wall mounting bracket and screws this instruction manual a warranty card Carefully unpack and verify that all items are on hand. INSTALLATION Leveling Models DS10L, DS20L, and DS44L are equipped with adjustable leveling feet. Adjust the four leveling feet under the platform to level it.

AC Adapter Receptacle OPERATION Turning the Scale ON With no load on the platform, switch the scale ON by pressing the ON/ OFF/RE-ZERO button. When first switched ON, all segments of the display should be on as shown in the illustration. This display check will be displayed briefly, then zero will be displayed. When zero is displayed, the balance is ready for use.
Checking Calibration Before using the scale, calibration should be verified. The scale has been calibrated before shipment, however, calibration is influenced by factors such as: • Variations in the earths gravitational field at different latitudes of the world. • Rough handling. • Changes in work location. • Height above sea level. To check the scale’s calibration, place a traceable calibration mass on the center of the platform and read the displayed weight.
Taring When weighing material or objects that must be held in a container, taring stores the container weight in the scale’s memory and subtracts it from the total weight on the platform. 1. Place an empty container on the platform. Its weight will be displayed. 2. Press ON/OFF/RE-ZERO to rezero the display. The container’s weight will be stored in memory. 3. Add material to the container. As material is added, its net weight will be displayed. 4.
Calibration NOTE NOTE: This procedure requires that the scale must be ON ON. Calibration can be in made in pounds or kilograms. 1. Remove all weights from the platform. 2. Press ON/OFF/RE-ZERO to turn ON the scale. The display should show either 0.00 kg or 0.00 lb. 3. Press ON/OFF/RE-ZERO and hold for fifteen seconds seconds, the display will show 0.00 kg or 0.00 lb.

Repeated pressing of the ON/ OFF/RE-ZERO button will switch between kg and lb on the display. OR 4.
CARE AND MAINTENANCE To keep the scale operating properly, the indicator and platform should be kept clean and free from foreign material. If necessary, a cloth dampened with a mild detergent may be used. Keep calibration weights in a safe dry place. TROUBLESHOOTING SYMPTOM PROBABLE CAUSE(S) REMEDY Unit will not turn on. Power adapter not plugged Check power adapter in or properly connected to connections. Charge scale or batteries are low. batteries. Incorrect weight reading.
Error Messages Overload: The load on the platform exceeds the capacity of the scale. Underload: Platform has been removed. Low Battery: NiCad battery pack must be charged.
