terminal if the current to be measured is
less than 200 mA. If the current is between
200 mA and 10 A, connect the red test lead
to the 10 A terminal instead.
2. Set the range switch to desired
position. Note: If the magnitude of the current
to be measured is not known beforehand,
set the range switch to the highest range first
and then reduce it one range at a time until
the appropriate resolution is obtained.
3. Turn off power to the circuit to be tested.
Then discharge all capacitors.
4. Break the circuit path to be tested, and
connect the test leads in series with the
circuit.
5. Turn on power to the circuit.
6. Read the reading on the display. The polarity
of the red test lead connection will be
indicated.
WARNING: To avoid risk of personal
injury and/or possible damage to the meter,
when using the 10 A terminal, you should only
acquire readings for 10 seconds maximum with
a minimum resting time of 15 minutes between
readings.
WARNING: To avoid electric shock or
damage to the meter, do not apply terminals to
amperage higher than 200 mA when connected
to the terminal. Do not apply terminals to
amperage higher than 10 A when connected to
the 10 A terminal.
Measuring Resistance
1. Connect the black test lead to the COM
terminal and the red test lead to the
terminal.
2. Set the range switch to desired
position.
3. Connect the test leads across the object to
be measured.
4. Read the reading on the display.
Note:
1. For measurements >1000 kΩ, the meter
may take a few seconds to stabilize the
range reading. This is normal for high resistance
measurements.
2. When the input is not connected, i.e. at open
circuit, "1" will be displayed as an overrange
indication.
WARNING: To avoid electric shock or
damage to the meter, before measuring in-
circuit resistance, disconnect all power to the
circuit to be tested and discharge all capacitors
thoroughly.
Continuity Test
1. Connect the black test lead to the COM
terminal and the red test lead to the
terminal.
2. Set the range switch to the
3. Connect the test leads across the object to
be tested.
4. If the resistance is lower than approximately
30 Ω, the built-in buzzer will sound.
WARNING: To avoid electric shock or
damage to the meter, before performing
continuity test, disconnect all power to the
circuit to be tested and discharge all capacitors
thoroughly.
Diode Test
1. Connect the black test lead to the COM
terminal and the red test lead to the
terminal. Note the polarity of the red test lead
is positive (+).
2. Set the range switch to the
3. Connect the red test lead to the anode of the
range
diode to be tested and the black test lead to
the cathode of the diode.
