Battery Replacement

When the battery icon appears empty
remove the water tank before replacing the batteries and replace it afterward.
 Remove the water tank cover using the meter's side tabs, and remove the water tank.
 The battery compartment is located at the bottom of the meter. Three Philips head screws
provide access. Use care when removing the screws as they each include a rubber
grommet for protection against moisture and should not be discarded or lost.
 Replace the four (4) 1.5V 'AAA' batteries observing polarity.
 Replace the battery cover and water tank before operating the meter. Ensure that the cotton
wick is immersed in the water bottle and that the meter housing is closed before operating
the meter.
