* CODE2 is also usable as a Key LOCK terminal.
(Refer to " ■ B4 terminal function selection" on page 35.)
(2) G/N (GROSS/NET) switching <Edge input> (B5)
The weight value of the main unit and indicator is switched.
The ON edge (OFF → ON) of the external input will result in gross display (GROSS).
The OFF edge (ON → OFF) of the external input will result in net display (NET).
(3) D/Z (Digital zero) <Edge input> (B6)
The ON edge (OFF → ON) of the external input will zero the gross weight.
However, the range that can be zeroed is within the DZ regulation value. Out of this range, zero
will not result, but "ZALM" will light.
(4) TARE ON (Tare subtraction) <Edge input> (B7)
The ON edge (OFF → ON) of the external input will result in immediate tare subtraction to zero
the net weight.
(5) TARE OFF (Tare subtraction reset) <Edge input> (B8)
The ON edge (OFF → ON) of the external input will reset the above tare subtraction. However,
the tare setting is not cancelled.
(6) HOLD (Hold) <Level input> (B9)
As long as the external input is ON, the weight value and comparison are held.
* "HOLD" lights during holding.
* This input terminal can be set to judgment input. It cannot be used for holding in the sequence
mode and when over/under comparison is made by external judgment.
(7) JUDGE (Judgment) <Level input> (B9)
This is valid when over/under comparison is set to external judgment input. (Refer to page 24.)
* This input terminal can be set to HOLD.
