Various Functions

Pattern Select Function

This function stores up to eight patterns of scaling data and comparator data, and allows the users to set patterns as desired.
Pattern selection can be controlled either via terminals or via front keys according to the condition data setting. In case of control via terminals, short the terminals between P.SEL1 to 3 and COM or make them equipotential to enable pattern switching from P-1 up to P-8. In case of control via front keys, hold down the increment key for approx. 3 seconds to switch patterns.

Start Hold Function

This function holds the display at the desired timing. Either A or B type can be set according to the condition data.
A type is a free run mode. In the free run condition, shorting S/H and COM terminals or making them equipotential will hold the displayed value and the comparison judgment value.
B type is a one-shot mode. In the hold condition, shorting S/H and COM terminals or making them equipotential will output the displayed value and the comparison judgment value once.

Peak Hold Function

This function holds any of the maximum (peak) value, the minimum (valley) value, and the difference between the maximum and the minimum (peak – valley) and outputs the value held. (The value to be held is switched according to the condition data.)
Shorting S/H and COM terminals or making them equipotential will turn ON the peak hold function.

Digital Zero Function (Display reset function)

This function forcibly zeros the displayed value. It is useful when subtracting tare weight during load measurement with load cells connected.
Display reset (Digital zero) function ON/OFF can be controlled via terminals or via front keys according to the condition data setting.
In case of control via terminals, shorting the terminals between DZ and COM or make them equipotential to turn ON the display reset function. In case of control via front keys, hold down the shift key for approx. 3 seconds to turn ON the function.
