BANTE ECscan10 Pocket Conductivity Tester User Manual

BANTE ECscan10 Pocket Conductivity Tester

Overview

Thank you for selecting the ECscan series pocket conductivity tester. This user manual provides a step-by-step guide to help you operate. the tester, please carefully read the following instructions before use.

Installing the Batteries

1.  Remove the battery compartment lid.
2.  Insert three LR44 alkaline batteries into the battery compartment, note polarity.
3.  Replace the battery compartment lid to its original position and turn clockwise until tight.

Keypad

Function

1. Switch the tester on or off
2. Lock or unlock measurement
3. Exit calibration and return to the pH measurement
4. Start calibration
5. Select the pH buffer option
6. Confirm the calibration or displayed option
7. Toggle between pH and temperature measurement modes (For PHscan20 tester only)

Prior to Use

Remove the protective cap and translucent cover from the bottom of the tester. If the platinum sensor has dried out, soak the electrode for about 10 minutes in tap water.

Switching the Tester On and Off.

1.  Press and hold the Meas key for about 5 seconds to switch on the tester.
2. Press and hold the Meas key to switch off the tester.
   If you do not press any key within 8 minutes, the tester will switch off automatically to conserve energy.

Conductivity Calibration

The ECscan10 conductivity tester allows 1 point calibration. For better accuracy, we recommend calibrating the tester regularly. The following table shows acceptable standard solutions for each tester.

1. Model Standard Solution Range Default
2. ECscan10 L 100 to 180 μ S/cm 146.5 μ S/cm
3. ECscan10 M 1000 to 1800 μ S/cm 1413 μ S/cm
4. ECscan10 H 10 to 18 mS/cm 12.88 mS/cm

Make sure that use a fresh standard solution during the calibration. DO NOT reuse the standard solution after calibration, contaminants in the solution will affect the calibration and eventually the accuracy of the measurement

1.  Rinse the electrode with distilled water and place it into the standard solution, stirring the tester gently to remove air bubbles trapped in the slot of the sensor.
2.  Press and hold the Cal key to enter the calibration mode, the  display shows
3.  Press the up / down key to set the calibration value, make sure that the displayed value matches the calibration standard.
4.  Press the Meas key, the calibration value will automatically flash three times.
5.  Press the Meas key again, the tester returns to the measurement mode, the CAL icon disappears from the display. Calibration is completed.

• During the calibration, if the display shows indicating that the measured conductivity value deviates from the theoretical value of the standard solution. The calibration will not be accepted. Please replace the fresh standard solution and calibrate the tester again.
• During the setting, pressing and holding the up/ down key will make the value change faster.
• If you want to exit the calibration, DO NOT press the Meas key in step 4. Press and hold the up / down key until the display shows —, press the Meas key to exit.

Measurement

Conductivity Measurement
Rinse the electrode with distilled water, place the electrode into the sample solution and stir gently, make sure that no air bubbles on the sensor surface. Wait for the measurement to stabilize and record the reading.

• During the measurement, DO NOT completely immerse the tester in water.
• Press the lock key, the tester will lock the measurement, the HOLD icon appears on the display. Press the key again to resume measurement.
• If the display shows 1 indicating the measurement exceeds the range, remove the tester from the sample immediately.

Temperature Measurement

• Press the oC key, the tester shows the temperature readings.
• Press the Meas key to return to the conductivity measurement.

Electrode Maintenance and Replacement

• Rinse the electrode thoroughly with distilled water after use.
• Do not touch the platinum black coating on the sensor surface and always keep it clean.
• If there is a build-up of solids inside the sensor, remove them carefully, then recalibrate the tester.
• If you do not use the tester for long periods, store the electrode with tap water.

Replacing the Electrode

If the tester fails to calibrate or gives fluctuating readings, you should consider replacing the electrode.

1. If the tester fails to calibrate or gives fluctuating readings, you should consider replacing the electrode.  away from the tester.
2.  Align the slot on the new electrode, gently push the electrode into the tester.
3. Twist the electrode collar clockwise until tight.
