The DC Voltage ranges are: 400.0mV, 4.000V, 40.00V, 400.0V and 1000V. To measure DC voltage, connect the Meter as follows:
1. Insert the red test lead into the
HzV
Ω
Ω
terminal and the black test lead into the
COM
terminal.
2. Set the rotary switch to
; DC measurement is default or press
BLUE
button to select DC measurement mode.
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 10M
Ω
. This loading effect 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).
•
When DC voltage measurement has been completed, disconnect the connection between the testing leads and the circuit under
test, and remove the testing leads away from the input terminals of the Meter.
Measurement Operation (2)
B. AC Voltage Measurement (see figure 4)
Warning
To avoid harms to you or damages to the Meter from electric shock, please do not attempt to measure voltages higher than
1000VDC / 750VAC rms although readings may be obtained.
The AC voltage ranges are: 4.000V, 40.00V, 400.0V and 750.0V. To measure AC Voltage, connect the Meter as follows:
1. Insert the red test lead into the
HzV
Ω
Ω
terminal and the black test lead into the
COM
terminal.
2. Set the rotary switch to
and press
BLUE
button to select
AC
measurement.
3. Connect the test leads across with the object being measured. The measured value shows on the display.
