IV. Calibration (you will need two 100g calibration weights and one
50g calibration weight)

scale to “CAL” then set scale right side up again.
2. With the scale “OFF”, press and hold both the TARE and the
ON/OFF keys at the same time for about 5 seconds. A random number
will be displayed.
3. Place a 100g weight on the tray and wait 5 seconds.
4. Press the ON/OFF key. The display will show 100.0 and then an-
other random number. Do not remove the weight yet.
5. Add a 50g and another 100g weight to the platform and wait 5 sec-
onds. (there should now be 250g of weight on the scale)
6. Press the ON/OFF key. The display will show 250.0 and then PASS.
7. Press the ON/OFF to finalize calibration. You may now turn off the
scale and return the switch on the bottom to “Normal”.
