(DC 12V adapter are available) OPERATING INSTRUCTIONS Power On Turn on the power by pressing the power button for 2 seconds. Once on, the scale will ash the voltage and then begin to auto-check and count down from 0-9 sequentially before entering the weighing mode Note: Anything on the scale before powering on will automatically be tared out.

    Hold There are 4 different hold functions you can choose from in the C11 parameter 1.Peak Hold: Grabs the highest weight (for materials testing, ie. tension and pulling force) Press the HOLD key then add weight to the scale The indicator will show the highest weight it recorded and hold it on the screen until a higher weight is placed on the scale 2.Manual Hold: Grabs the current weight and holds it so it will not change/fluctuate While weighing, press HOLD and the indicator will hold the current weight on the screen until...
  • Page 10 . The display will count down from 10-1 while the scale is calibrating zero. When the display shows 0 the zero calibration is complete. OP-909 offers 2 calibration methods, Single Point which uses one weight to calibrate or Linear Calibration, which uses multiple (2-7) weights for a more accurate calibration.
