of Thermo-sensitive resistor and moves to the next item
[C-11]. When the ZERO switch in place of the ON/OFF
switch is pressed, the scale moves to the next item
[C-11] without storing the reference count for current
output of Thermo-sensitive resistor.
14 With [C-11] on the display, press the ON/OFF switch.
The display indicates [CAL0].
15 Make sure that nothing is placed on the scale and wait
for the Stable mark to turn on.
16 Press the ON/OFF switch.
The scale stores the zero point data and moves to the
next item [C-12].
When the ZERO switch in place of the ON/OFF switch is
pressed, the scale moves to the next item [C-12] without
storing the zero point data.
17 With [C-12] on the display, press the ON/OFF switch.
The display indicates [CAL1].
18 Place a 150-kg (weighing capacity) weight on the scale
and wait for the Stable mark to turn on.
19 Press the ON/OFF switch.
The scale stores the span data and moves to the next
item [END].
When the ZERO switch in place of the ON/OFF switch is
pressed, the scale moves to the next item [END] without
storing the span data.
20 After the scale indicates [END], the power is turned off automatically.
Remove the weight from the scale. Calibration has been completed.
NOTE
A room with a temperature of around 25 ºC with little temperature change
is needed. Perform calibration only after the temperature of a scale and
the temperature of room are the same. Place the scale on a level surface,
and after pre-load do not move the scale until calibration is over.
