3.10.2 To calibrate 0% saturation

Figure 60 : 0% saturation calibration Screen

1. Press MODE key to select % Saturation mode.

2. Immerse the DO probe in 0% solution. Stir gently to create a homogenous

solution.

3. Press CAL key to calibrate the meter. The meter shows ‘Dissolved O

Calibration-Rinse Electrode’ screen [Figure 48(a)] for few seconds to

prompt user to rinse electrode with de-ionized water before calibration.

4. The meter then shows saturation calibration screen [Figure 60].

5. Wait for the reading to stabilize.

6. The primary display will show the current value of measurement.

7. Press ENTER key to confirm the calibration. The meter automatically

calibrates to 0% saturation and returns to the measurement mode [Figure

59].

Note: The keys that appear in 0% saturation calibration mode functions similar

to the one as described in 100% saturation mode. (Refer page 66)

3.10.3 % DO Calibration Report

Calibration report gives you detailed information for the % saturation. It

includes date & time, 0% and 100% saturation mV value, % saturation offset

calibration and barometric pressure at which the solution was measured.

Note: If you wish to completely re-calibrate the meter, you need to clear

previous calibration data. Press CLR-C (F2) key to clear previous

calibration. The meter shows you confirmation screen. Press ENTER key

to confirm deleting previous calibration. It will clear all the calibration

data including mg/L data.
