Battery and Fuse replacement
The meter uses a single standard 9V alkaline battery (NEDA1604A, JIS6AM6,
IEC6LF22), a 500V/0.63A IR 200kA fast acting F fuse (FS 1) for
µ
A/mA current input,
and a 600V/15A IR 100kA fast acting F fuse (FS 2) for A current input.
Loosen the screws from the case bottom. Lift the end of the case bottom nearest the input
jacks until it unsnaps from the case top. Replace the battery and the blown fuse(s).
Replace the case bottom, and ensure that all the gaskets are properly seated and the two
snaps on the case top (near the LCD side) are engaged. Re-fasten the screws.
