MEASUREMENT OPERATION
Overrange Indication: „1" is shown on the display. In case
the "1" is shown on the display stop the measurement
and choose another measurement area.
A. DC Voltage Measurement
V
Warning
To avoid harms to you or damages to the Meter from
eletric shock, do not attempt to measure voltages
higher than 250V AC/DC, although readings may be
obtained.
The DC Voltage ranges are:
200.0mV, 2.000V, 20.00V, 200.0V and 250V.
To measure DC voltage, connect the Meter as follows:
1. Insert the red test lead into the terminal
and the black test lead into the COM terminal
2. Set the rotary switch to V

3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
Note
• In each range, the Meter has an input impedance of
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 AC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads
from the input terminals.
