Soak electrode for a few minutes in alcohol to remove oils. 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 cor rects 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. 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 compartment 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. 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 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.
