Instrument disassembly
Instrument disassembly and reassembly is required for the service tasks described below, sensor water barrier replacement and
sensor replacement. Optionally charge the instrument after reassembly.
Using a torx screwdriver,
loosen all four captive screws
on the battery.
Lift the battery away from the
instrument.
Using a torx screwdriver,
loosen the case bottom's
remaining two screws.
Hold the case bottom near
the upper screws. Lift the
case top slightly to separate
it from the case bottom.

Continue to lift the case top
straight up to remove it.
Near the top of the circuit board assembly, hold the plastic sides that border the sensors.
Gently lift the circuit board assembly straight up and away to separate it from the case top.
Sensor water-barrier replacement
—
Inside the case top, grip the
sensor water barrier with the
needle-nose tweezers. Peel
to remove.
Remove any remnants of the
adhesive or water barrier.
Clear away any dirt, dust, or
debris.
Place the water-barrier sheets
on the work surface.
Using the tweezers, scrape
lightly across the paper to the
barrier's edge; gently lift to
expose a portion of the
adhesive back.
Grip the barrier lightly with the
tweezers and peel it from the
packet.
Guide the new water barrier—adhesive side down—into the
case top.
For proper placement, take care to ensure the barrier edge
meets the inner edge of the case top's sensor opening.
Using care not to touch the filter's white membrane, press on
the filter edge to support adhesion.
