Flow rate
It is normal zero calibration performed manually using zero
calibration solution for each measurement item.
50 mL/min
Keep zero calibration solution in the calibration tank. Using
button operation, switch the liquid from the sample water to zero
calibration solution and start calibration.
80 mL/min
It is performed manually using common zero calibration solution
for the three items: turbidity, color and residual chlorine. Filtering
sample water using the filter inside the device generates zero
80 mL/min calibration solution. Button operation for starting calibration
switches the sample water flow from the normal measurement
line to the filter line and starts calibration.
This operation does not use the calibration tank.
It is performed automatically using common zero calibration
solution for the three items: turbidity, color and residual chlorine.
Filtering sample water using the filter inside the device
generates zero calibration solution. Button operation for starting
calibration switches the sample water flow from the normal
80 mL/min
measurement line to the filter line and starts calibration.
The calibration solution tank is unused as well as common zero
calibration.
You are required to set the first calibration date and time and
interval between calibrations.
It is general span calibration performed manually using span
calibration solution for each measurement item. Keep span
50 mL/min
calibration solution in the calibration tank. Button operation for
starting calibration switches the liquid from the sample water to
span calibration solution and starts calibration.
80 mL/min
It is performed to adjust the value measured by the device to
match the value analyzed manually or measured using another
80 mL/min instrument using running sample water (tap water). Performed
manually.
Calibration solution and the calibration tank are not used.
