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 compar tment 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.
