Battery and Fuse replacement
Battery use:
Single 9V battery NEDA1604, JIS006P or IEC6F22;
or 9V alkaline battery NEDA1604A, JIS6AM6 or IEC6LF22
AM-120 & AM-130 fuses:
Fuse (FS1) for
μ
AmA current input: 0.63A/500V, IR 200kA, F fuse (FA-6x32/.63);
Fuse (FS2) for A current input: 12.5A/500V, IR 20kA, F fuse (FA-12.5A/500V)
AM-150 fuses:
Fuse (FS1) for
μ
AmA current input: *1A/1kV, IR 10kA, F fuse (FA-1A/1000V)
Fuse (FS2) for A current input: **15A/1kV, IR 10kA, F fuse (FA-15A/1000V)
*A 0.44A/1kV, IR 10kA fuse is also recommended since it has a Time-Current
Characteristic Curve projection of approaching infinity at 0.5A. It can also be loaded
way beyond 1000 seconds at 1 A, and has a fast acting characteristic of below 0.01
second at beyond 2.5A.
**A 11A/1kV, IR 20k fuse is also recommended
Battery replacement:
Loosen the 2 screws from the battery access door of the case bottom. Lift the battery
access door and thus the battery compartment up. Replace the battery. Re-fasten the
screws.
Fuse replacement:
Loosen the 4 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 blown
fuse(s) and/or the battery.
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.
