Electrode Maintenance
1. Rinse the electrode with tap water or electrode storage solution after each
measurement.
2. In aggressive chemicals, dir ty or viscous solutions, and solutions with heavy
metals or proteins, take readings quickly and rinse electrode immediately afterward.
3. If possible, keep a small piece of paper or sponge in the electrode cap – moistened
with clean water or electrode storage solution (NOT de-ionized water) – and close
the cap over the electrode.
Changing Batteries
1. Open battery compartment lid (with attached lanyard loop).
2. Remove old batteries; replace with fresh ones. Note polarity.

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.3. Align the four tabs on the new module so that they
match the four slots on the tester (see picture B).
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.
Note: It is necessary that you recalibrate your tester prior to measurement after an
electrode replacement.
Applications
