Warning
To prevent possible electrical shock, fire, or personal injury,
•
Remove the input signals before you clean the Product.
•
Use only specified replacement parts.
To clean the external surfaces of the Product, wipe the case with a damp cloth and mild
detergent. Do not use abrasives or solvents.
Dirt or moisture in the terminals can cause incorrect measurements and can falsely set off
the Input Alert feature. Clean the terminals as follows:
1.
Turn off the Product and remove all test leads.
2.
Shake out dirt that can be in the terminals.
3.
Soak a clean swab with mild detergent and water. Move the swab around in each
terminal. Dry each terminal with canned air to push the water and detergent out of the
terminals.
It is recommended that the Product be calibrated by Fluke in 2 year intervals.

Warning
To prevent possible electrical shock or personal injury, use
only specified replacement fuses with the amperage, voltage,
and speed ratings shown in Table 3.
Fuse Test
As shown in Figure 1, with the Product in the
N
function, put a test lead into the
jack and place the probe tip on the other end of the test lead against the metal of the
current input jack. If
LEAd
appears in the display, the probe tip has been inserted too far
into the amps input jack. Lift the lead out a bit until the message no longer shows in the
display and
0L
or a resistance measurement shows in the display. The resistance value
must be as shown in Figure 1. If the tests give measurements other than those shown,
have the Product serviced.
