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.
