c. Connect the test leads across with
the object being measured.
The measured value shows on the
display.
NOTE
• If the value of voltage to be measured
is
unknown,
measurement position (1000V) and
reduce the range step by step until a
satisfactory reading is obtained.
• The LCD displays "1" indicating the
existing selected range is overloaded,
it is required to select a higher range
in order to obtain a correct reading.
• In each range, the Meter has an input impedance of approx. 10MW. This loading
effect can cause measurement errors in high impedance circuits. If the circuit
impedance is less than or equal to 10kW, the error is negligible (0.1% or less).
When DC voltage measurement has been completed, disconnect the connection
between the testing leads and the circuit under test.
2. DC CURRENT TESTING (see Fig. 2)
WARNING: Never attempt an in-
circuit current measurement where the
open circuit voltage between terminals
and ground is greater than 250V .
If
the

measurement,
the
damaged or the operator himself may
be hurt. Use proper terminals, function,
and range for the measurement. When
the testing leads are connected to the
current terminals, do not parallel them
across any circuit.
The measurement ranges of DC current
are: 200.0 mA and 10.00 A.
To measure current, do the following:
a. Turn off power to the circuit.
Discharge
capacitors.
b. Insert the red test lead into the mA or 10A terminal and the black test lead
into the COM terminal.
c. Set the rotary switch to an appropriate measurement position in
d. Break the current path to be tested. Connect the red test lead to the more
positive side of the break and the black test lead to the more negative side
of the break.
e. Turn on power to the circuit.
The measured value shows on the display.
NOTE
• If the value of current to be measured is unknown, use the maximum
measurement position (10A) and 10A terminal, and reduce the range step by
step until a satisfactory reading is obtained.
• When DC current measurement has been completed, disconnect the connection
between the testing leads and the circuit under test.
• At 10A Range: for continuous measurement
between 2 measurements greater than 15 minutes.
