8. BASIC OPERATION
8.1. 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.
When the optional sealed lead acid (SLA) battery (OP-02) is used:
After all the display symbols appear, the battery capacity status is displayed for
about 1.5 seconds as shown below.
Level Display Battery capacity status
1 “ bat ooo ” Full capacity
2 “ bat _oo ”
3 “ bat __o ”
4 “ bat ___ ” No capacity (Low battery)
At level 3, prepare to recharge the battery.
At level 4, recharge the battery immediately. (Refer to “13.1. Using the OP-02
SLA battery”.)
After the weight value internally becomes stable, the display turns off for a moment,
and then, zero is displayed along with the ZERO indicator (power-on zero).
If the weight value is unstable, “
------ ” is displayed. Check if anything touches
the weighing pan, or if there is a strong draft or vibration. 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, “
------ ” is
displayed. 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 “11.
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 and hold 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.
