There are 3 type of setting values for each comparison.

(1)Set the limit value (upper and lower limit / HiHI, Hi, Lo, LoLo limit).

(2)Set the Target value and an acceptable tolerance (upper and lower) in weight. The limit value is calculated automatically.

(3)Set the Target value and an acceptable tolerance (upper and lower) in percentage of the target weight. The limit value is calculated automatically.

Example. Target = 50kg, Upper limit = 51kg, Lower limit = 48kg

(1)Hi (Upper limit): 51 (kg), Lo (Lower limit): 48 (kg)

(2)TG (Target): 50 (kg), Hi (Upper acceptable tolerance): 1 (kg),

Lo (Lower acceptable tolerance): 2 (kg) not a negative value

(3)TG (Target): 50 (kg), Hi (Upper acceptable tolerance): 2 (% of Target), Lo

(Lower acceptable tolerance): 4 (% of Target) not a negative value

10.1.1.Condition formula for Comparison

Comparison is performed based on the following formula.

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.
