Symptom Cause Corrective Action
Voltage reading higher than
20 mV during “Electrode
Functionality Check”
Meter is connected
to charger
Disconnect the meter from the charger.
Low battery charge Recharge battery for 12 hours.
Electrode not equilibrated Condition the electrode as outlined in “Equilibrating the Electrode”.
Dirty electrode tips Clean the electrode as outlined in “Electrode Cleaning”.
Conductive contamination
between electrodes
Inspect the inter-electrode surface areas for material which could form
a conductive bridge between the inner and outer electrodes. If the
material cannot be removed, replace the electrode.
Corrosion on electrode
conductive traces
Inspect the embedded copper circuit traces that run from the electrode
tip and up the handle. If any black discoloration is observed at the tip,
replace the electrode.
