4.1.6 Setting Output Range
Set the analog output range selection (local/remote) and the range. (When shipped from the
factory, this is set to local range selection and to RANGE1 (0 to 2 mg/l).)
For output range setting, see Section 5.2.
4.1.7 Running-in
Carry out running-in for an hour or more while allowing “zero water” to fl ow.
4.1.8 Zero and Span Calibrations
After the indication is stable, zero calibration and span calibration is made in use of zero water
and calibration plate respectively.
First, carry out zero calibration.
1. Set FUNCTION “1” in the <MAINT.> mode. --> “Turbidity value” is displayed.
2. Wait for the indication to stabilize, and then press [ENT] --> [>] --> [ENT] keys in this order to
carry out zero calibration.
Next, carry out span calibration.
1. Set FUNCTION “D.” In the <PROGRAM1> mode and con
fi rm that “on” is displayed. “on”
means the calibration using the calibration plate (“on” is set when shipped from the factory).
2. Set FUNCTION “4” in the <MAINT.> mode. --> “Turbidity valve” is displayed.
3. Set to the drain status.
• Close V2 and open V5 (for Suf fi x code: -A1).
• Close V2 and open SV1 (for Suf fi x code: -A2).
• Close SV3, SV4 and open SV1 (for Suf fi x code: -A3).
4. Loosen screw A at the lower part of the detector to open the detector (see Figure 4.1).
5. Set the attached calibration plate as shown in Figure 4.4 (the calibration plate is housed in
the converter).
6. Close the detector and tighten screw A.
7. Wait for the indication to stabilize and press [ENT] --> [>] --> [ENT] to calibrate.
8. Open the detector and remove the calibration plate and then tighten screw A.
