OPENING THE MOOSHIMETER

WARNING

To avoid electric shock, disconnect test leads from

the meter before opening the meter.

1.

Disconnect all test leads.

2.

Unscrew both retaining screws from the bottom of the
case with a Phillips head screwdriver.

3.

Separate the two halves.

4.

Taking special care not to bend the circuit board, grasp
the circuit board as shown near the connectors and pull it
out of the top half of the enclosure.
