2 Preparing the Meter for Operation Power Considerations 120 Figure 2-1. Replacing the Line Power Fuse eue20.eps Current-Input Fuses The 200 mA and 10 A inputs are protected by user-replaceable fuses. • The 200 mA input is protected by a fuse (F2) rated at 440 mA, 1000 V (fast blow), 10,000 A minimum breaking capacity. • The 10 A input is protected by a fuse (F1) rated at 11 A, 1000 V (fast blow), 10,000 A minimum breaking capacity. XW Warning For protection against fire or arc flash, replace a blown fuse with a fuse of an identical rating. To test the current-input fuses: 1. Turn on the Meter and plug a test lead into the INPUT VZYR HI terminal. 2. Press O. 3. Press Vto set the range to 200 Ω. Only the 200 Ω, 2 kΩ, and 20 kΩ ranges can be used to test the mA input fuse. 4. Insert the other end of the test lead into the mA terminal. If the fuse is good, the Meter displays a reading of 0.000 Ω. If the fuse is blown, the Meter displays 0L to indicate an overload. 5. Remove the test lead from the mA terminal and insert it into the 10 A terminal. If the fuse is good, the Meter displays a reading of

Figure 2-1. Replacing the Line Power Fuse
Current-Input Fuses
The
200 mA
and
10 A
inputs are protected by user-replaceable fuses.
•
The
200 mA
input is protected by a fuse (F2) rated at 440 mA, 1000 V (fast
blow), 10,000 A minimum breaking capacity.
•
The
10 A
input is protected by a fuse (F1) rated at 11 A, 1000 V (fast blow),
10,000 A minimum breaking capacity.
XW
Warning
For protection against fire or arc flash, replace a blown fuse
with a fuse of an identical rating.
To test the current-input fuses:
1.
Turn on the Meter and plug a test lead into the
INPUT V
ZY
R
HI
terminal.
2.
Press
O
.
3.
Press
V
to set the range to 200
Ω
. Only the 200
Ω
, 2 k
Ω
, and 20 k
Ω
ranges can
be used to test the mA input fuse.
4.
Insert the other end of the test lead into the
mA
terminal. If the fuse is good, the
Meter displays a reading of 0.000
Ω
. If the fuse is blown, the Meter displays
0L
to indicate an overload.
5.
Remove the test lead from the
mA
terminal and insert it into the
10 A
terminal.
If the fuse is good, the Meter displays a reading of <1.000
Ω
. If the fuse is blown,
the Meter displays
0L
to indicate an overload.
XW
Warning
To avoid electric shock, remove the power cord and any test
leads from the Meter before opening the current-input fuse
cover.
To replace the current-input fuses:
