DC current measurement (A
⎓
)
•
Connect the black test lead to the “COM” terminal.
•
If the expected current is between 200mA and 5A, connect the red test lead to the
“VΩmAhFE” terminal.
•
Turn the function switch (3) to appropriate current range position.
•
Open the circuit to be measured, then connect the test leads in series with the load under
measurement.
•
The measured current value will be displayed.
•
If the current value to be measured is unknown, start the measurement with the highest
current range.
•
For the 5A range, the measurement time should be less than 10 seconds, then allow 15-
mintue cooling time before the next measurement.

Resistance measurement (Ω)
•
Connect the black test lead to the “COM” terminal, while the red test lead to the
“VΩmAhFE” terminal.
•
Turn the function switch (3) to appropriate resistance (Ω) range position.
•
Connect the test leads across the load to be measured.
•
The measured resistance value will be displayed.
•
Note:
The measured value of a resistor in a circuit is often different from the resistor's rated
value because the meter’s test current flows through alternative path in the circuit.
