Battery Replacement
Changing Batteries:
1.) Open battery compartment lid (located near the
LCD screen).
2.) Remove and replace the old batteries. Note po-
larity shown in battery compartment. When inserting
new
batteries,
take
care to place them
over the white removal
tab. This will make fu-
ture battery removal
much easier.
3.) Recalibrate meter
after
every
battery
change.
Maintenance:
To improve performance and avoid transferring soil-
borne diseases, clean the sensor tip by rinsing in al-
cohol for 5 - 10 minutes.
Replace all batteries if low battery indicator appears,
or if readings are faint or unstable.
Store the probe sensor dry.
Important: Do not touch the sensor tip with your
fingers. The oils on the skin will affect the
probe’s measurement accuracy.
