Use the proper AC adapter 2. The lab scale need warm up before use, so turn on the balance, wait for 5-30 minutes before use Attention 1. Stay away from electromagnetic interference sources such as microwave ovens, mobile phones 2. It must be calibrated before use Installation 1. A clean and stable environment, Do not use the balance near ventilated, magnetic field 2. The horizontal foot should be adjusted 12 different kinds of Unit 1. g (gram), oz (ounce), lb (pound), ozt 2. ct (carat), t, dwt, Kg 3. dr, mg, GN(grain), N Two ways of Calibration Nonlinear Calibration Turn on the scale, without adding any object to the scale pan, press and hold the "CAL" button until the display shows “--CAL-”,then off the handWait a moment, the LCD display will flash the weights(short press MODE button can change the weight)Put the proper weight on the plate, wait for senconds Linear Calibration Same as the nonlinear calibration step 1Press and hold the "UNIT" button until the display shows “--CAL-”, then off the handPlace the weights according to the flashing weight, and remove all the weights after the displayed weight values stabilize
