5 Operation
5.1 Display
Power up sequence:
1、All LED segments light on for 2 seconds.
2、Upper display shows software number, lower display shows version number. for example,
upper display shows [000292]，lower display shows [V 1.5].
3、enter into weighing display, if current load is under power-up zero range, the terminal execute
power-up zero operation.
Note:
1、if F2.7 is set to 0, power-up zero is disable, the terminal display current weight based on last
working zero, if there is tare during last turn off, tare can be reserved and displayed in next turning
on.
2、if F2.7 parameter is nonzero, and weight is within power-up zero range, the terminal execute
power-up zero operation. If current gross weight is over this setting power-up range the upper
display shows [E0], or show [- - - - - -] if the weighing signal is in motion.
3、If F6.10=1, the power-up zero is disabled and the terminal display current weight based on last
working zero during turning off.
