Tester Maintenance
• To improve performance, clean the electrode
byrinsingtheminalcoholfor10to15minutes.
• Replace all batteries if low battery indicator
appears,or ifreadings arefaint orunstable.
• Ifyouexperience drift,periodicallylet electrode
fully dry.
When you need a new electrode, see “Electrode

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.
