Step 3 :
Press the " CAL. Button " ( 3-3, Fig. 1 ) once again,
display value of " 200.00 g " will flash 6 times, then the
calibration procedures are finished completely & balance
is ready for the measurement accurately.
3) Calibration under the 100 gram standard weight
a) Power on the scale until the display show zero value.
Apply the 100 gram standard to the center of the
platform gently. If the scale is not accurate, then may
show the weight value around 100 g ( for example 99.94 g
, 100.05 g.....)
Step 1 :
b)
Press the " CAL. Button " ( 3-3, Fig. 1 ) once,
display will show the value of " 100.00 g "
Step 2 :
Press the " CAL Button " ( 3-3, Fig. 1 ) once again,
display value of " 100.00 g " will flash 6 times, then the
calibration procedures are finished completely & balance
is ready for the measurement accurately.
Consideration of Self-Calibration :
* The internal Self-Calibration value is saved to the
internal EEPROM circuit permanently. Once power off then
power on, the calibration value will be not disappeared .
* After make the self calibration, measure the 100 g or 200 g
standard weight again, if the display value existing few
counts deviation, it is normal. However within few hours,
the balance will be kept under a high accuracy condition.
Those accuracy will be even better than the published
specification ( refer page 2 ).
* Under the status of " oz " unit, still can use the weight of
100 g or 200 g to make the calibration. However the " g "
marker will disappear.
