Bante904P Portable Conductivity/DO Meter

DO Calibration in % Saturation Mode
The Bante904P portable conductivity/dissolved oxygen meter is able to perform either 1
or 2 points calibration in the dissolved oxygen mode.
For single point
calibration,
we recommend that you perform 100% saturation calibration in the air-saturated water. If the 2 points calibration is selected, the zero oxygen
solution needs to be used.
Single point calibration - 100% saturation
1.1
Press the
Mode
key until the meter shows
icon and measurement unit
“
%
”.
1.2
Ensure that you have selected 1 point calibration in the setup menu.
1.3
Press the
Cal
key, the meter shows 100.0%/CAL 1.
1.4
Hold the dissolved oxygen probe in the air at 100%
relative humidity or place the probe into the air-saturated water for 15 minutes. Press the
Enter
key, the meter begins the calibration, the Calibration icon continuously flashing.
1.5
Wait for the reading to stabilize, the meter automatically shows END. Calibration is completed.
2 points calibration
2.1
Ensure that you have selected 2 point calibration in the setup menu.
2.2
Press the
Cal
key, the meter shows 100.0%/CAL 1, press the
or
key until the display shows 0/CAL1.
2.3
Immerse the dissolved oxygen probe into the zero oxygen solution for at least 10 minutes. Press the
Enter
key, the meter begins the calibration, the
Calibration icon continuously flashing.
2.4
Wait for the reading to stabilize, the display will
show “100
%
/CAL2”
, the meter prompts you to continue with second point calibration.
2.5
Immerse the dissolved oxygen probe into the air-saturated water for 15 minutes, press the
Enter
key to confirm. Wait for the reading to stabilize, the
meter automatically shows END. Calibration is completed.
Performing a percentage saturation calibration will simultaneously calibrate the corresponding mg/L (or ppm) concentration value. Therefore,
additional mg/L calibration is not required in most circumstances.
