DISPLAY AND KEY DESCRIPTION ON/OFF Powers the Indicator On or Off if held for 2 seconds TOTAL Accumulates weights HOLD 1. Peak hold - Grabs the highest weight (for tension and pulling force) 2. Data hold - Holds the current weight value (ex. for use with weighing moving animals) UNIT Shifts between weighing units (kg/lb) -
Page 9: Operating Instructions
OPERATING INSTRUCTIONS Power On ● Turn on the power by pressing the power button for 2 seconds. Once on, the scale will flash 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. - Page 10 Accumulation ● The accumulation function is used to add multiple weights and total them together ● In weighing mode load the first weight, once stable press the ACCUM key to enter the accumulation mode. The “total” light will display ● Remove weight and press ZERO key before adding the second weight to the scale ●...
- Page 11 Hold In the parameter settings you can choose one of these 5 hold options 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 ●...
