Replacing the Battery

(see fig 5)

1.

Disconnect the connection between the testing leads and the cir-
cuit under test when battery indicator appears on the display.

2.

Turn the Meter to OFF position.

3.

Remove the screw, and separate the case bottom from thecase 
top.

4.

Replace the battery with a new 9V battery (NEDA 1604 or 6F22 
or 006P).

5.

Rejoin the case bottom and case top, and reinstall the screw.

Replace the fuse 

(see fig 5)

1.

Disconnect the connection between the testing leads and the cir-
cuit under test.

2.

Turn the Meter to OFF position.

3.

Remove the screw and separate the case bottom from the case 
top.

4.

Remove the fuse by gently prying one end loose, and then take 
out the fuse from its bracket.

5.

Replace only fuses with the identical type and specification as 
follows. 315mA, 250V, fast type, 5x20mm.

6.

Rejoin the case bottom and case top, and reinstall the screw. 
Replacement of the fuses is seldom required. Burning of a fuse 
always results from improper operation.
