Replacing the Battery

(Fig 6)

Replace the battery when the battery indicator appears on the display.

1. Disconnect the connection between the testing leads and the circuit under test when battery indicator

appears on the display.

2. Turn the Meter to OFF position.

3. Remove the screw, and separate the battery lid.

4. Replace with a new 9V battery type 6F22.

Replace the fuse

(Fig 7)

Replacement of the fuses is seldom required. Burning of a fuse always results from improper operation.

1. Disconnect the connection between the testing leads and the circuit under test.

2. Turn the Meter to OFF position.

3. Remove battery lid, holster, screws and separate case bottom.

4. Replace only fuses with the identical type 0,315A 250V, fast type, 5x20mm.
