(when the unit is "m
-1
") 10.00 to 500.00
1.000 Abs

VIS.
Setting range: Abs and m
-1
Abs
VIS

3
TURB. COR.
FAC.
Sets the turbidity correction factor.
Setting range: 0.000 to 9.999
0.000
COD
MEAS. RANGE
Sets the measurement range.
Setting range: 0.100 to 9999.999
1.0 mg/L
DECIMAL
PLACE
Sets the decimal place of the measurement value.
Setting range: 0 to 3
1
y = a + bx
Sets the COD conversion factor a and b by calculating from
UV-
VIS.
Setting range: a
9999.999 to 9999.999
b 0.001 to 9999.999
Up to five pairs of the COD conversion factors “a” and “b” are
available.
a = 0.0
b = 1.000
MAX ALARM
VALUE
Sets the upper limit of COD alarm value.
Setting range:
9999.999 to 9999.999
1.0
MIN ALARM
VALUE
Sets the lower limit of COD alarm value.
Setting range:
9999.999 to 9999.999
0.0
TURB
(turbidity)
MEAS. RANGE
Sets the measurement range.
Setting range:
9999.999 to 9999.999
1.0 deg.
DECIMAL
PLACE
Sets the decimal place of the measurement value.
Setting range:
9999.999 to 9999.999
1
y = a + bx
Sets the TURB Meas. correction factor “a” and “b”.
Correction is possible when the readings differ from the actual
value due to the various causes even after calibration.
Setting range: a
9999.999 to 9999.999
b 0.001 to 9999.999
a = 0.0
b = 1.000
MAX ALARM
VALUE
Sets the upper limit of TURB (turbidity) alarm value.
Setting range:
9999.999 to 9999.999
1
MIN ALARM
VALUE
Sets the lower limit of TURB (turbidity) alarm value.
Setting range:
9999.999 to 9999.999
0
UNIT
Sets the measurement unit of TURB (turbidity).
Setting range: deg., mg/L, and NTU
deg.
