DC Voltage Measurement

(Figure 2)
Warning
To avoid harms to you or damages
to the Meter from electric shock,
please do not attempt to measure
voltages higher than 500 V
although readings may be obtained.
The DC Voltage ranges are: 200mV, 2000mV,
20V, 200V and 500V. To measure DC voltage,
connect the Meter as follows:
1. Insert the red test lead into the VΩmA
terminal and the black test lead into the COM
terminal.
2. Set the rotary switch to an appropriate
measurement position in V
3. Connect the test leads across with the object
being measured. The measured value shows
on the display.

range.
Note:
If the value of voltage to be measured is unknown, use
the maximum measurement position (500V) and reduce
the range step by step until a satisfactory reading is

obtained. The LCD displays
"1" indicating the existing
selected range is overload; 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. 10MΩ.
This loading effect can cause
measurement errors in high
impedance circuits. If the
circuit impedance is less than
or equal to 10kΩ, 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.
