ONGOING MAINTENANCE
A.
Replace Electrode
It is recommended the ORP electrode be replaced every 6 to 12
months or as needed. Some applications can severely limit
the life span of an ORP electrode.
1. Unscrew the electrode collar to
remove the electrode & ATC
assembly as shown in the right
figure
.
2. Remove the old electrode from
the
electrode collar.
3. Insert a new electrode, make sure the electrode fit back into the
meter correctly.
