6. BASIC OPERATION
6-1. Turning the power ON and OFF
1. Press the ON/OFF switch to turn the power ON.
All the display symbols appear and the scale waits for the weight value to become
stable.
After the weight value internally becomes stable, the display turns off for a moment
and zero is shown with the ZERO indicator (power-on zero).
If the weight value is unstable, the display shows “
------
”. Check if anything
touches the weighing pan, or check if there is strong wind or vibration. And
eliminate the cause of the error.
The range for power-on zero is within ±50% of the weighing capacity (kg) around
the calibrated zero point.
If the power is turned ON while there is a load beyond this range, the scale shows
“
------
”. Remove the load from the weighing pan.
‰ If the scale is to be turned ON with some item loaded, performing a zero calibration
with the item loaded will allow the scale to turn ON that way. (Refer to “9.
CALIBRATION”.) In this case, make sure that the total weight of the item loaded at
power-on and the object to be weighed is within the weighing capacity.
2. Press the ON/OFF switch to turn the power OFF.
‰ Auto power-off function
The auto power-off function automatically turns the power OFF, if zero is displayed
for approximately 5 minutes.
Refer to “10-2. Function list” to set “
poff ”. The auto power-off function has been
enabled at the factory.
