before use.
Inserting the Batteries
Take out the three "G13A" button cell batteries from the packaging. Follow the steps
below to insert the batteries into the battery compartment.
• Remove the battery compartment lid. Insert the batteries into the battery
compartment, noting polarity.
• After installation, replace the battery compartment lid and turn it clockwise until it
is tight.
Prior to Use
Remove the electrode protective cap from the tester. If the electrode bulb dries out, soak
the electrode module in storage solution or tap water for at least 15 minutes. Do not use
distilled or deionized water, as it will shorten the sensor's life.
