Electrode Replacement

When the tester fails to calibrate or gives fluctuating readings in calibration

standards, you need to change the electrode module. You can replace the

electrode module at a fraction of the cost of a new tester.

1. With dry hands, grip the ribbed tester collar with electrode facing you. Twist the

collar counter clockwise (see Figure13-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 of the new electrode module so that they match the four

slots on the tester (see Figure 13-B).

4. Gently push the module into 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.

Note:

Note: It is necessary that you recalibrate the tester prior to measurement after

an electrode replacement.

Changing Batteries

Replace the batteries when the low battery indicator

starts blinking.

1. Open the battery compartment lid (with attached

lanyard loop).

2. Remove old batteries by pulling plastic ribbon.

Replace with fresh ones. Note polarity as shown in

figure 11.

Electrode Maintenance

1. Always keep the sensor electrodes clean. Rinse the electrodes with de-ionized

water and wipe them dry with clean cloth before storing with its protective cap.

For cup type electrodes, remove the white plastic cup and insert to thoroughly

clean viscous solutions. Never scratch electrodes with a hard substance.

2. For better performance, soak the electrode in alcohol for 10 to 15 minutes

and rinse with de-ionized water before starting any measurement process.

This is to remove dirt and oil stains on the electrode which may affect the

accuracy of the measurements.
