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.

Electrode Replacement
You can replace the electrode module
at the fraction of the cost of a new
tester. When the tester fails to calibrate
or gives fluctuating readings in
calibration standards, you need to
change the electrode.
1. With dry hands, grip the ribbed tester
collar with electrode facing you. Twist
the collar counter clockwise (see picture
A). Save the ribbed tester collar and
O-ring for later use.
2. Pull the old electrode module away from
the tester.
3. Align the four tabs on the new module
so that they match the four slots on the
tester (see picture B).
4. Gently push the module onto the slots
to sit it in position. Push the smaller
O-ring fully onto the new electrode
module. Push the collar over the module
and thread it into place by firmly twisting
clockwise.
