<Reference> Individual zero calibration and span calibration
<residual chlorine>
Preparation
Calibration tank…2
Zero standard solution…1 L (Pour the solution into one of the calibration tanks)
Span standard solution…1 L (Pour the solution into the other calibration tank)
Used fluid tank (Install it so that used fluid goes into the tank)
Calibration procedure
Perform calibration in the order: individual zero calibration
→
span calibration.
Individual zero calibration
1.
Place the calibration solution tank with zero liquid more than 170 cm above from
the drain pipe outlet; instead of placing it on the calibration tank tray beside the
device.
2.
Connect the tank to the calibration inlet of the device.
3.
