V: Measuring signal, a voltage signal from the detector
T2: Turbidity value after correction
K: Sensitivity correction factor
This is calculated in the calibration of item (5) in Table 5.4, and can be displayed and changed using item (12) in
Table 5.4.
The permissible range in items (5) and (12) in Table 5.4 is 0.25 <= K <= 4.00.
B: Zero-correction coefficient
This is calculated in item (3) in Table 5.4 and can be displayed and changed using item (11) in Table 5.4.
-9 mg/L <= B <= 9 mg/L is the permissible range for items (3) and (11) in Table 5.4.
Note 1: Turbidity in the <MEAS.> mode is displayed in T2 (turbidity after correction). However, when the turbidimeter is shipped from
the factory, the zero and sensitivity correction factors are 0.0 mg/L and 1, respectively. Thus, T1 = T2.
Note 2: For zero and span calibration of (1), (2), (4), and (8) referencing the standard solution, T1 (turbidity before correction) is
always displayed as turbidity.
