Question & Answer Q1 What if the balance is not accurate? A1 Please do the calibration for the scale. The scale comes with a calibration weight. The calibration steps is : you need to press and hold the "CAL" button for 5 seconds, the scale will display the value of the weight , then you just put the weight on the scale until the value display, all is done. Q2 Can it weigh in oz/square yard also? A2 The balace only can display the 'g', but it's easy to calculate the oz/square yard. For example, and the gsm of the sample fabric= 500gsm(The GSM = 100cm² Sample weight(g) * 100), so the oz/square yard= 500*0.02949=14.745oz/square yard( 1 gsm=0.02949 oz/square yard). Note1: The disc cutter comes with one pcs of rubber pad. the pad belongs to consumables, if it broken, you need buy it yourself. Note2: Machine preheating; power on for more than one hour for accurate measurements. Note3: Do not disconnect the AC adapter when temporarily not in use, press POWER/BEK to put it in standby mode. Release the side fixer Hold the middle part, rotate the red knob to adjust the blade depth. Counterclockwise - blade retracted Clockwise - blade released Tighten the fixer after blade adjustment.
