uncovered Meter assembly on a protective surface. When the
case of the Meter is open, circuit connections are exposed.
To open the Meter case, refer to Figure 2 and do the following:
1.
Disconnect test leads from any live source, turn the rotary knob to
OFF
, and remove
the test leads from the front terminals.
2.
Remove the battery door by using a flat-blade screwdriver to turn the battery door
screws 1/4-turn counterclockwise.

The case bottom is secured to the case top by three screws and two internal snaps (at
the LCD end). Using a Phillips-head screwdriver, remove the three screws.

To avoid damaging the Meter, the gasket that is sealed to the
bottom case, and is between the two case halves, must remain

easily. Do not damage the gasket or attempt to separate the
case bottom from the gasket.

Pushing up from the inside of the battery compartment, disengage the case top from
the gasket.
