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.
