1YH-T6 USER MANUAL1. Function of the keys:Switch key: It uses to press turn off under weighing mode and press turn on under power off mode: Accumulative-clear key: It uses to exit under calibration mode: Kg/lb switch key: It uses to move flash bit to left side under calibration modeAccumulative-add key: It uses to move flash bit to right side under calibration mode:Tare key: It uses to add the number on the flash bit under calibration mode or switch parameter.: Zero key: It uses to confirm under calibration mode2. Power on and off1).Press around 3 seconds. it begins to self-inspect, then it enters to weighing mode.(power-on to pre-heat 15-30 minutes) If you use rechargeable battery, first you also have to power on,but remember to charge the battery fully when using the rechargeable battery at the first time.2).After power on, if the indicator vibrates from zero point, but it is still in auto zero range (±10% against full span),it will come to zero automatically, then zero-point light is on; If it is out of auto zero range, you have to adjust thezero point or re-calibrate.3).Press around 3 seconds to exist the weighing mode.3. Zero-setting operation:If gross weight of the system is in manual zero range (±2% against full span), press to make the indicatorshow zero, but if it has tare weight, the indicator can’t be zero.4. Tare operation:When gross weight is over zero and the system is stable, press to tare, the tare light is on; When the systemreturns to zero point and still has tare weight, press to exit the net weighing mode, tare weight returns to zeroand tare light is off, the system returns to gross-weight weighing mode. The max accumulative weight is 999999(decimal point excludes)5.
