Safety Information

"Warning" and "Caution" Statements

A “XW Warning" identifies hazardous conditions and actions that could cause bodily harm or death. A "W Caution" identifies conditions and actions that could damage the Meter, the equipment under test,

or cause permanent loss of data.

XWWarnings and Precautions

To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following practices:

• Use this meter only as specified in this manual or the protection provided

by the Meter might be impaired.

• Before using the Meter, inspect the case. Do not use the Meter if it is

damaged. Look for cracks or missing plastic. Pay particular attention to the insulation around the connectors.

• Inspect the test leads for damaged insulation or exposed metal. Check the

test leads for continuity. Replace damaged test leads before using the Meter.

• Verify the Meter’s operation by measuring a known voltage. Do not use the

Meter if it operates abnormally. Protection may be impaired. When in doubt, have the Meter serviced.

• Do not apply more than the rated voltage, as marked on the Meter, between

the terminals or between any terminal and earth ground.

• Use caution when working with voltages above 30 V ac rms, 42 V ac peak,

or 60 V dc. These voltages pose a shock hazard.

• Use the proper terminals, function, and range for your measurements.

• Do not operate the Meter around explosive gas, vapor, or dust.

• When using the probes, keep fingers behind the finger guards.

• When making connections, connect the common test lead before

connecting the live test lead; when disconnecting, disconnect the live test lead before disconnecting the common test lead.

• Disconnect circuit power and discharge all high-voltage capacitors before

testing resistance, continuity, diodes, or capacitance.

• Before measuring current, check the Meter's fuses (see "Testing the

Fuses") and turn OFF power to the circuit before connecting the Meter to the circuit.

• Do not operate the Meter with the case (or part of the case) removed.

• Use only a single 9 V battery, properly installed in the Meter case, to power

the Meter.

• Replace the battery as soon as the low battery indicator (b) appears. With a

low battery, the Meter might produce false readings that can lead to electric shock and personal injury.

• Remove test leads from the Meter before opening the Meter case.

• When servicing the Meter, use only specified replacement parts.

• When replacing the fuses, use ONLY Fluke-specified fuses as listed in

Table 5.

XWWarning

To avoid electrical shock or personal injury:

• Remove the test leads and any input signals before replacing the battery or

fuses.

• To avoid electrical shock, arc blast, or damage to the Meter, install only

fuses with the amperage, interrupt, voltage, and speed ratings specified in Table 5.

To test the fuses (refer to Figure 1):

1. Set the Rotary Switch to e.

2. Plug a test lead into the VeG terminal and touch the probe to the

10 A terminal (to test the 11 A Fuse).

400 mA (to test the 440 mA Fuse)

• If the display shows a resistance value in the range shown in Figure 1, the fuse is good.

• If the display reads

OL, replace the fuse and test again.

• If the display shows any other value, have the Meter serviced. See “Service Information” earlier in

this manual.
