Connecting the Electrode Holder

Bante810 benchtop dissolved oxygen meter comes with an easy-to-use holder for mounting the DO probe. If necessary, follow the steps below to install the

electrode holder.

1. The base of the electrode holder with an irregular round hole.

2. The electrode arm has a plastic rod.

3. Insert the plastic rod into the irregular round hole and swivel the electrode arm 90o. Electrode holder is now ready to swing into desired position.

ADJUSTMENT OF ELECTRODE ARM:

After installation, if the electrode arm automatically rises or falls, you need to adjust the screws until arm locate at any position.

1. Remove the plastic cover from the electrode arm.

2. Use the screwdriver to tighten the screw moderately.

3. Insert the plastic cover to previous position. Installation is completed.

Connectors

The meter provides 2 connectors for connecting the various types of sensors. Listed in the below table are the details of these connectors.

Refilling Electrolyte Solution for DO Probe

1. Take out the DO probe from the packaging. Unscrew the membrane cap from the probe.

2. Fill the membrane cap halfway with electrolyte solution.

3. Screw the membrane cap onto the probe, excess electrolyte will drain out.

4. Be sure the cathode of probe makes contact with membrane cap, the electrolyte solution in membrane cap should be without an air bubble.

Connecting the DO Probe

1. Place the DO probe into left or right sides of the electrode arm.

2. Insert the 6-pin connector into corresponding connector socket, ensure that the connector is fully seated. After connection is completed, DO NOT

pull on the sensor cord. Always make sure that the connector is clean and dry.

Connecting the Power Adapter

1. Before plugging in the power adapter, ensure the voltage of power adapter matches your local main voltage.

2. Insert the connector of power adapter into the meter power socket, the meter is now ready for use.

Prior to Use

Turn on the meter 10 to 15 minutes and wait for the probe to polarize.

Power On/Off

●Press MEAS key to turn on the meter, the display shows measured value.

●Press and hold the MEAS key for 5 seconds, the meter will turn off.

●If you do not press any key for 3 hours, the meter will turn off automatically.

To disable the auto-off function, please read the SETUP MENU section.

Setting the Default Parameters

1. Press and hold the key for 3 seconds to enter setup menu, the meter shows selected salinity coefficient.

2. Press or key to set the parameter, press ENTER key to confirm. The meter goes to barometric pressure option, the display shows 760mmHg.

3. Press or key to set the barometric pressure value, press ENTER key to confirm. The meter goes to calibration point selection mode, the

display shows 1 point calibration.

4. Press or key to select the number of calibration points, press ENTER key to confirm. The display shows concentration unit “mg/L”.

5. Press or key to select the measurement units, press ENTER key to confirm. The meter shows “HOLD/NO” indicating that the auto-hold

function is disabled.

If the auto-hold function is enabled, the meter will automatically sense a stable endpoint reading and freeze it. If you disable this function, the meter

allows you to freeze the reading by pressing the HOLD key.

6. Press or key to enable or disable the auto-hold function, press ENTER key to confirm. The meter shows “OFF/NO” indicating that the auto-off

function is disabled.

When the auto-off function is enabled, if you do not press any keys within 3 hours, the meter will automatically turn off.

DO Calibration in % Saturation Mode

Bante810 benchtop dissolved oxygen meter can be calibrated quickly in air. In the percentage saturation mode, the meter is able to perform either 1 or 2

points calibration. For single point calibration, we recommend that you perform 100% saturation calibration in the air. For the 2 points calibration, you need

to use zero oxygen solution.

100% SATURATION CALIBRATION:

1.1 Make sure that you have selected 1 point calibration in the setup menu.

1.2 After the DO probe connected with the meter, turn the meter on 10 to 15 minutes to polarize the sensor.

1.3 Press CAL key, the meter shows “CAL1/100%”.

1.4 Hold the DO probe in the air or place the sensor into air-saturated water for 3 to 5 minutes. Press ENTER key to confirm. Wait for the measured

value to stabilize, the display shows “END”. Single point calibration is completed.

2 POINTS CALIBRATION:

2.1 Make sure that you have selected 2 points calibration in the setup menu.

2.2 Repeat steps 1.2 to 1.4 above. When the first calibration point is done, the display shows “CAL2/0%”. The meter prompts you to continue with

second point calibration.

2.3 Submerse probe in the zero oxygen solution, stir the sensor gently.

2.4 Press ENTER key to confirm. Wait for the reading to stabilize (this can often take more than 10 minutes), the display shows “END”. The meter

returns to measurement mode. Calibration is completed.

Performing a percentage saturation calibration will simultaneously calibrate the corresponding mg/L ( or ppm ) concentration value. Therefore,

additional mg/L calibration isn’t required in most circumstances.
