Measurement Operation (1)
A.DC Voltage Measurement
(see figure 3)
(figure 3)
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 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 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
l
In each range, the Meter has an input impedance of 10M .
This loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less than or
equal to 10k , the error is negligible (0.1% or less).
l
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.
