6-6. Power on zero
The power on zero function makes the display to a zero if the changes of display is within ± 10 % of the
maximum capacity when the power is turn on, or in the stable condition in the operation of display turning
on.
6-6-1. The operation of power on zero
[Effective] and [Invalidity] of the power on zero operation are selected by C function CF-15.
[Effective] is selected as a default.

The zero compensation is not accepted in the following condition when the setting of C functions CF-15 is
[Effective power on zero] and when power on zero is starting.
(1) When the display is not a stable condition, it becomes as all lighting.
(2) When the measurement value exceeds
±
10 % of the maximum capacity, [ ] is displayed. At
this time, if key is pressed, it compulsorily becomes a load value display.

When the power on zero is executed, each data of tare weight cancellation, fixed tare weight cancellation, zero
set and zero tracking shall be all cleared.
6-7. Tare weight cancellation
By pressing key, the display of [TARE] and [NET] in the condition display section blinks and change
to zero.
To execute the tare weight cancellation clear, press key when the gross value is zero.
The tare weight cancellation is cleared and [GROSS] of the condition display section lights on at the same
time as becoming a gross value display.
6-7-1. Operating condition of tare weight cancellation
The operating condition of tare weight cancellation is selected by C function CF-16.
[Operation when it is steady] or [Operate unconditionally] can be selected.
Default has selected [Operation when it is steady]

The tare weight cancellation is not accepted when gross value is below the zero.

The tare weight cancellation is not accepted when the gross value is larger than the first range.

When zero set is executed in a condition of gross value display, the tare weight cancellation is cleared.
6-8. Setting of record place of set data
It is able to switchover the recording of TARE data and zero data as RAM  EEPROM.
Switchover the recording place of TARE data and zero set data which RAM or EEPROM by C function
CF-17. However, the recording place of TARE DATA and zero set data will be RAM in case of the setting
of the C function CF-15 is [Valid].
It is preserved almost permanent because EEPROM is nonvolatile.
Moreover, RAM data disappears in power supply OFF because RAM is not backed up.
