5.1. Basic weighing operation
1. Touch the switch to turn the power ON.
All the symbols except the comparator LEDs are
displayed. When the weight values becomes
stable, the display turns off for a moment and
displays zero (power-on zero) with the weighing
unit used last before turning off.
2. Select a weighing unit using the
UNITS
switch.
See “6. SELECTING A WEIGHING UNIT” in
detail.
3. When the display doesn’t show zero, tap the
switch to set the display to zero.
4. When using a tare (container), place the
container on the weighing pan, and tap the
TARE
switch to set the display to zero.
5. Place the object to be weighed on the weighing
pan or in the container, and wait for the STABLE
indicator to turn on and read the value.
6. Remove the object from the weighing pan.
7. Touch and hold the switch. Then, the
scale displays “
0ff
” and turns the power off.
5.2. Notes about operations
Power-on zero
If the weight is unstable at power ON, the scale displays “
------
”. Check anything
touches the weighing pan, or check if there is strong wind or vibration.
The range for power-on zero is within ±50% (±10% for Legal for Trade models) of
the weighing capacity (kg) at the calibrated zero point. If the scale is powered on
with a load beyond this range, the scale displays “
------
”. Remove the load from
the weighing pan.
ZERO and TARE
The (as ZERO switch) and
TARE
switches work when the weight value
is stable.
The switch will zero the scale if the weight value is within ±2% of the
weighing capacity (kg) at the power-on zero point. The ZERO ◄ indicator turns on.
