5-2 Setting of the discrimination value of the comparator function
There are two ways of inputting a reference value and upper and lower limit values as described below:
- Actual value setting method: Weighing a sample with a balance and then making it a setting value.
- Numeric value setting method: Inputting a setting value directly via key operation.
The discrimination is performed according to the following criteria:
- Absolute value: The discrimination is performed based on the upper and lower limit values that have
been set in advance.
- Relative value: A reference numeric value is set in advance, and the discrimination is performed
based on the range defined by the upper and lower limit values that have been set
for the reference numeric value.
（
For example
）
Two-point (upper and lower limits) setting, Reference value = 100.00 g,
Lower limit value = 90.00 g, Upper limit value = 120.00 g

Reference value Lower limit value Upper limit value
100.00 g 90.00 g 120.00 g
Absolute value 90.00 g 120.00 g
Relative value 100.00 g -10.00 g 20.00 g
