6.0 CALIBRATION

Before calibrating the scale, you should ensure that you have a suitable known weight for
calibration.
1. When in normal weighing mode with the scale at zero press and hold down [TARE] and
[ON / OFF] keys to enter the calibration mode.
2. If the calibration switch is in the off position on the main PCB inside the scale, the
indicator will show "CAL.OFF" and then exit this mode. If the indicator shows "CAL-?",
the scale is ready for calibration.
3. When the indicator shows "CAL-?", press the [TARE] key to confirm and go to next step,
or press the [ON / OFF] key to exit the calibration mode.
4. When '0.0' is displayed the scale will begin to calibrate the scale's zero-point. Ensure
that there is no load or weight on the scale's platform. Press the [TARE] key to confirm,
or press the [ON / OFF] key to exit this mode.
5. A few seconds after the [TARE] key has been pressed in step 4 the scale will show
"300.0" and the kg LED, or "600.0" and the lb LED depending on which unit you chosen,
this is the default calibration weight from the factory. Press the [UNIT] key to select the
calibration weight unit that you want to calibrate in. Press the [ON / OFF] key to exit the
calibration mode at this point or press the [Print/Hold] key to choose a different
calibration weight value (50kg, 100kg, 150kg, 200kg, 250kg, 300kg or 100lb, 200lb,
300lb, 400lb, 500lb, 600lb); Then put on the weight that you selected and press the
[TARE] key to confirm the chosen standard weight that was selected earlier. The
displayed data will flash on the display and if the scale accepts the calibration data it will
calculate and store the information into the EEPROM. If an error has occurred, the scale
will display "CAL. Er" and return back to step 4 for re-calibration. If the loaded weight is
not within the range of 95% to 105% of the weight value you selected, the scale will not
calibrate but display "CAL. Er" and return back to step 4 for re-calibration. )
6. Check the calibration by putting the weight that you calibrated at back on the scale, if it
is off repeat the calibration process again.
