Maintenance
Handling
DO NOT lay instrument on display with
wet electrode since the liquid may enter
the instrument case through the base of
the electrode creating a short or circuit
board damage. Shake the instrument
vigorously after each use to remove ALL
water from the side of the pH electrode
and inside of the conductivity electrode.
Cleaning
Both electrodes are equipped with
protective caps. The bottle on the pH
electrode protects the glass bulb inside
the plastic sleeve , protects it from
contamination and prevents it from
drying out. The red cap on the
conductivity electrode prevents fluid
from entering the electrode when only
pH is being measured and reduces the
need for cleaning. Clean both electrodes
before storing to prevent build-up of
sediment and to assure long life.
