Waterproof ECScan High Instructions

Before You Begin

Remove electrode cap. Soak electrode for a few minutes in alcohol to remove oils.

Calibration

Tester is factory calibrated. However, to ensure accuracy, calibrate conductivity on a regular basis.

Select a calibration standard appropriate for the

ECScan High tester (between 2.00 mS and

19.90 mS). It is best to select a standard close

to the test solution value.

1. Open battery compartment lid (end with lanyard loop).

2. Orientate the battery compar tment as shown in Diagram 1.

3. Rinse electrode in deionized water, then rinse it in calibration standard, then dip it

into a container of calibration standard.

4. Switch unit on (ON/OFF key). Wait several minutes for display to stabilize.

5. Press the INC or DEC key to adjust reading to match the calibration

standard value.

6. After 3 seconds without a key press, the display flashes 3 times, then shows ‘ENT’. The tester accepts calibration value; returns to measurement mode.

7. Replace battery cap.

Conductivity Testing

1. Remove electrode cap. Switch unit on (ON/OFF key).

2. Dip electrode into test solution. Make sure sensor is fully covered.

3. Wait for reading to stabilize (Automatic Temperature Compensation corrects for temperature changes). Note reading.

4. Press ON/OFF to turn off tester. Replace electrode cap. Note: Tester automatically shuts off after

8.5 minutes of non-use.

HOLD Function

Press HOLD key to freeze display. Press HOLD again to release.

Tester Maintenance

• To improve performance, clean the electrode by rinsing them in alcohol for 10 to 15 minutes.

• Replace all batteries if low battery indicator

appears, or if readings are faint or unstable.

• If you experience drift, periodically let electrode

fully dry.

When you need a new electrode, see “Electrode Replacement” on insert in back of box.

Self-Diagnostic Messages

bAt Weak batteries–replace with fresh ones specified by manufacturer.

Err Wrong keypress.

Or, Ur Over range/Under range signal, or electrode

is not in contact with solution, or electrode is failing.

---- Calibration mode activated but not performed.
