voltages higher than 1000V, although readings may
be obtained.
The DC Voltage ranges are: 4V, 40V, 400V and 1000V;
To measure DC voltage, connect the Meter as follows:
14
1. Insert the red test lead into the V terminal and the
black test lead into the COM terminal.
13
2. Set the rotary switch to V
to select DC measurement mode.
3. Connect the test leads across with the object being
12
measured.
The measured value shows on the display.

Note
The Meter has an input impedance of 10M Ω This
Description
can cause measurement errors in high impedance
circuits. If the circuit impedance is less than or equal
to 10k Ω , the error is negligible (0.1% or less).
Special care should be taken when measuring high
voltage.
When DC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads
away from the input terminals of the Meter.

Warning
Never attempt an in-circuit current measurement
where the open circuit voltage between terminals
and ground is greater than 60V DC or 30V rms.
If the fuse burns out during measurement, the Meter
may be 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.
Before the Meter is connected in series to the circuits
being tested, turn off the power of the circuits.

Note
If the value to be measured is unknown, use the
maximum measurement position and reduce the
range step by step until a satisfactory reading is
obtained.
When the measured current is 5A, continuous
measurement is allowed.
When the measured current is between 5A-10A,
continuous measurement 10 seconds and interval
more than 15 minutes.

Warning
To avoid harm to you, please do not attempt to input
voltage higher than 60V DC or 30V rms AC.
To avoid damage to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before measuring resistance.
The resistance ranges are:400Ω, 4kΩ, 40kΩ,400kΩ,
4MΩand 40MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the Ω terminal and the
black test lead into the COM terminal.
2. Set the rotary switch to Ω
