Thoroughly rinse the DO probe with DI water; Dry it with a soft tissue on the
membrane surface. To calibrate with air, put the probe in a well-ventilated area.
OR calibrate with water saturated with air as below,
Swirl the probe at a speed of 20–80 cm/s or stir the water to produce a similar linear
speed. Keep the flow speed constant during calibration. Ensure there is no air bubble
trapped under the membrane.
From the initial state or while measuring, press [Calibrate]; Select Full Scale. Press
[Enter]; when reading becomes stable, press [Enter] to automatically record the Full
Scale response. This ends Full Scale Calibration.
 Zero Oxygen Calibration
Prepare zero-oxygen water by dissolving 12.5 g AR grade anhydrous sodium sulfite in
250 mL DI water; Soak the measuring tip in zero oxygen water and gently shake the
probe to remove bubbles on the gas permeation membrane surface; From the initial
state or while measuring, press [Calibrate]; Select Calib Zero; Press [Enter] to
select Zero Point Calibration. When reading becomes stable, press [Enter] to
automatically record the Zero Point value. This ends Zero Oxygen Calibration.
3.7 Conductivity Probe Calibration (Meters with Conductivity function)
3.7.1 Prepare the conductivity probe and connect it to the meter.
3.7.2 Calibrate the cell constant
 Prepare a standard solution (KCl) according to page 37 of 3200C User Guide.
 Ensure the meter is connected with both a conductivity probe and an ATC probe.
Record the actual temperature of sample solution.
 Disconnect the ATC probe. The meter will display 25.0 °C by default. Pay attention to:
If the temperature is set at 25.0 °C manually, conductivity displayed is without
temperature compensation.
 Rinse the conductivity probe with distilled or DI water. Soak the conductivity probe in
the standard solution.
 Press [Calibrate]. Select Cell Const.
 Press [Setup] to enter a Standard Solution Value (STD Value).You could find the
proper STD value on page 39 of 3200C User Guide with the temperature recorded.
 When the reading stabilizes, press [Enter]. The meter will calculate and set the new
cell constant. The calibration is done.
3.7.3 Calibrate the TDS
 Select a proper standard solution according to the nature and conductivity range of
sample.
 Set the cell constant to the value written on the probe label or recalibrate the probe to
get a new cell constant in 3.7.2.
 Press [Calibrate] and select TDS Factor. Press [Enter] to enter Calibration mode.
 Rinse the conductivity probe with DI water.
 The temperature of the calibration solution should be 25.0 ± 0.1 °C.
 Soak the conductivity probe in the standard solution.
 Press [Setup].
 Enter an STD value (mg/L) given in Table 6 on page 41 of 3200 C User Guide.
 When the reading becomes stable, press [Enter].
