WARNING
Do not use the meter if it is damaged. Before you use the meter,
inspect the case. Pay particular attention to the insulation
surrounding the connectors.
Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged test leads
before you use the meter.
Do not use the meter if it operates abnormally.
Protection may be impaired. When in doubt, have the meter
serviced.
Do not operate the meter where explosive gas, vapour, or dust
is present.
Do not apply more than the rated voltage, as marked on the
meter, between terminals or between any terminal and earth
ground.
Before use, verify the meter's operation by measuring a known
voltage.
When measuring current, turn off circuit power before connecting the meter in the circuit. Remember to place the meter in
series with the circuit.
To avoid possible electric shock or personal injury, follow these
guidelines:

WARNING
When servicing the meter, use only specified replacement
parts.
Use caution when working with voltage above 30 V RMS, 42 V
peak, or 60 V DC. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the finger
guards on the probes.
Connect the common test lead before you connect the live test
lead. When you disconnect test leads, disconnect the live test
lead first.
Remove the test leads from the meter before you open the
battery cover or the case.
Do not operate the meter with the battery cover or portions of
the case removed or loosened.
To avoid false readings, which could lead to possible electric
shock or personal injury, replace the battery as soon as the
battery indicator ( ) appears.
To avoid electrical shock, do not touch any conductor with hand
or skin.
Do not operate this instrument if your hand, a test lead or the
instrument is wet.
Remaining endangerment:
When an input terminal is connected to dangerous live potential
it is to be noted that this potential can occur at all other terminals!
CAT III -
Measurement Category III is for measurements performed in
building installation. Examples are measurements on distribution
boards, circuit breakers, wiring, including cables, bus-bars, junction
boxes, switches, socket-outlets in the fixed installation, and equipment
for industrial use and some other equipment, for example, stationary
motors with permanent connection to the fixed installation.
Do not use the meter for measurements within Measurement Categories
IV.

CAUTION
To avoid possible damage to the meter or to the equipment under
test, follow these guidelines:
●
●
●
●
Disconnect circuit power and discharge all capacitors before
testing resistance, diode, continuity and temperature.
Use the proper terminals, function and range for your measurements.
Before measuring current, check the meter's fuses and turn off
the power to the circuit before connecting the meter to the
circuit.
Before rotating the range switch to change functions, disconnect
test leads from the circuit under test.
