10.1.1. Condition Formula for Comparison
Comparison is performed based on the following formula.
Upper/lower comparison
Judge Condition Formula Display Output
HI Upper limit (Hi limit) value < Displayed value HI HI
OK Lower limit value
Displayed value Upper limit value
OK OK
LO Displayed value < Lower limit (Lo limit) value LO LO
5-stage comparison
Judge Condition Formula Display Output
HiHi HiHi limit value < Displayed value HI, 2 HI
HI Upper limit (Hi limit) value < Displayed value HI HI, OK
OK Lower limit value
Displayed value Upper limit value
OK OK
LO Displayed value < Lower limit (Lo limit) value LO LO, OK
LoLo Displayed value < LoLo limit value LO, 3 LO
The decimal point is not considered. Example: If the upper limit value is 10.0, enter 100.
These parameters are stored in non-volatile memory, and are not lost even if the
AC power is disconnected or cut off (except code 0 memory).
When the displayed value becomes an overload (positive over), HI (over) is output.
When the displayed value becomes an under load (negative over), LO (under) is output.
This function compares the Hi / HiHi limit value first.
This function does not check the relationship between the upper and lower limit values.
10.1.2. Setting the Upper/Lower Limit Values
Step 1 By pressing the SETPOINT key, the selected code memory number is displayed
and the first comparison class term (ex.Hi, TG etc.) is blinking.
Step 2 Select the comparison class using the following keys:
SETPOINT key ........The key to select a comparison class.
ESC key ..................The key to return to the previous stage (weight display or
code memory number select).
ENTER key..............The key to proceed to step 3.
Step 3 Set the setpoint values using the following keys.
0 - 9 key..................The key to enter a value.
ESC key ..................The key to proceed to the next comparison class (step 2)
without changing the set value.
ENTER key..............The key to store the value and proceed to the next
comparison class (step 2).
