t 2 / t 3 / t 4 : No contrast time t2 t3 t4 in fast feeding, moderate feeding and slow feeding to avoid feeding-crushed weight.
T5 : Over tolerance checking time t5 . T6 Fix value within time t6.
T7 Shut off discharging after time t7 when weight is less than near-zero value.
T8 time t8 to output alarm ERROR6 if
discharging signal is still effective after time t8.
T9 : Batching monitor time t9 to output alarm ERROR7 if batching process can’t finish after time t9.
3) In running status：
If stop input is valid, stop charging or discharding, return to stop status.
If pause input is valid, stop charging or discharging, operation input sparkles, press working then continue batching process, press stop then stop it.

DDDDDD —— 6bit，operation parameter value
For example：Write 30 command on operation parameter 7 in scale no.1:
02 30 31 57 55 37 30 30 30 30 30 30 30 33 30 36 31 0D 0A Correct response：
02 30 31 57 55 4F 4B 32 35 0D 0A
Means scale no. 1 has saved operation parameter 7.
Host computer write“Recipe no.”（only in stop status） Write command：
STX Scale no. W N DD CRC CR LF Correct response:
STX Scale no. W N O K CRC CR LF Wrong response:
STX Scale no. N N O CRC CR LF Here：
DD —— 2bits，range at 01-40，which is recipe no.
For example: Write recipe no. =01 on scale no. 1 command:
For example: Write recipe no. =01 on scale no. 1 command:
