Electrode Replacement
You can replace the electrode module at
the fraction of the cost of a new tester.
When the tester fails to calibrate, gives
fluctuating readings in buffers,shows
error messages ‘Er1’, ‘Or’ or ‘Ur’ in a
buf fer, and the procedures in the
Maintenance section do not help, 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.
