Joyfay USS-DBS3 Series Manual 

DESCRIPTION USS-DBS3 series electronics balance adopts load cell of a scene of types that resistance meets an emergency in high accuracy and microprocessor in high function and low power. It includes following function: automatic self-calibration. Tare, memory, count and error indications and simple manipulation by simple design! Light touch operation, easiness to see, simple cleaning. OPERATION 1. Place the balance on a smooth and steady table. Please adjust balance through adjust screws at the bottom of the balance if the table is not smooth or steady. Avoid vibration, sunshine, air movement and magnet. 2. The air temperature should be kept at about 5 ℃-35 ℃ at all times with a relative humidity level of about 50%-85%RH. 3. The balance accepts AC input voltages of 220V/50Hz or 110 V/60 Hz, DC input voltage of 9 V. 4. Please connect power supply and turn balance on. It will display “8.8.8.8.8.8.”, “Max, Capacity” and “_ _”step by step. You can use it after it displays “0.0”, “0.00” or “0.000”. (You had better warm the balance up for half an hour before using.) 5. Place the object you want to weigh on the balance pan, it will display the weight value. 6. Place a container on the balance pan if you want to weigh the object located in a container. Press “TARE/ZERO” key to zero the display. Place the object in the container; the balance will display the weight value. 7. Press “PCS” key for part count, the balance will display “PCS” and “10”. Choose average number from “10”, “20”, “50”, “150”, “200”, “250” to “500” by pressing “CAL”. Place “10”, “20”, “50”, “150”, “200”, “250” or “500” pieces of same object you want to weight on the balance pan, press “PCS” key to confirm. Please take the objects away from the balance pan. Now you can count object. Press “PCS” key if you want to escape count mode. 8. Press “UNIT” key for choosing weighing unit: g, ct, oz, lb. CALIBRATION Press and hold “CAL” for 5 seconds, the balance displays “CAL” and a weight value. Place relevant weights on the balance pan according to the weight values. At last, remove the weight, it displays “0.0”, “0.00” or “0.000”. You had finished the calibration.

please remove your object that time. 2. Please switch the balance pan according to the direction of hour hand if you want to remove the pan. Do not lift it up directly. 3. Error Information Table Error Informati on Specification Transaction ── It means that the object’s weight on the balance pan is less than 0 gram. Calibrate the balance ------ It means that the object’s weight on the balance pan is overload. Calibrate the balance Err-1 It means than you turn on and off the balance continuously. Turn the balance off. Then turn it on after 3 seconds. Err-2 It means that the object’s weight is not stable. Do not operate anything.
