Basic Operation
8.1.
Basic Operation of the Scale
Press the ON/OFF key to turn the power on.
Press the ON/OFF key again to turn the power off.
Although the display can be turned off with the ON/OFF key,
the internal circuit stays energized.
1. Turn the power on without placing anything on the weighing pan.
2. After all the display indicators turn on, the scale displays zero.
3. If the display does not show zero, press the ZERO key.
If the weighing value does not become stable, “
”
is shown. Confirm whether there is something touching the
weighing pan, or a strong breeze or vibration can be observed.
Zero-Point Setting
The ZERO key sets a zero point when the weighing value is stable within ± 2% of weighing capacity
based on basing the zero point (power-on zero) when the display turns on. The scale displays zero, and the
zero-point mark lights up.
Tare Subtraction
The TARE key subtracts the weight of substance on the weighing pan as the weight of tare (container)
when the weighing value is stable and more than zero. The scale displays zero, and the net weight mark and
zero-point mark light.
Caution: The weighing range is reduced by the tare weight.
Power-On Zero
When the ON/OFF key is pressed to turn on the display with nothing on the weighing pan, the scale
displays zero together with the zero-point mark lit. The range in which power-on zero is run is less than ±
50% of the weighing capacity for zero with sensitivity adjustment.
Power-On Tare
When the ON/OFF key is pressed to turn on the display with something on the weighing pan, tare
subtraction is run to light the net weight mark and the zero-point mark and to show zero. The range in which
power-on tare subtraction is run is ± 50% or more of the weighing capacity.
*Less than ± 50% of the weighing capacity: Power-on zero (zero-point mark lighting)
*± 50% or more of the weighing capacity: Power-on tare subtraction (net weight and zero-point marks lit)
Near Zero
Near zero is the range within ± 4d in kg (d = minimum display). This range is regarded as the standard for
functions being operated/not operated with comparators, etc.
