REMOVE THE OLD ELECTRODE

REPLACE THE ELECTRODE

(PictureB)

(PictureA)

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.
