4.8.3
Install the included software and USB driver
( See PC CD-ROM software user’s guide) on a PC.
Use the included USB cable to connect the meter
to the PC; the
symbol appears on the display.
Open the installed software and the meter will begin
sending the measured data to the software.
4.9.1 Move the rotary switch to the NCV
position.
4.9.2 Move the NCV sensor (top of the meter) toward the
object to be tested. If the sensor detects voltage
greater than 110VAC (rms), the NCV indicator will
flash and the meter will beep.
Note:
1.Even without indication, voltage may still exist. Do not
solely rely on NCV detection to determine in voltage
exists. Detection may be affected by socket design,
insulation thickness or other factors.
2.NCV indicator may go off when measuring voltage due
to the presence of induced voltage.
3.Interference sources may accidentally trigger NCV
detector.
4.10 DC/AC Voltage
Voltage is the potential difference between two points.
The polarity of AC voltage changes over time where DC
voltage polarity does not.

manual range.
Measuring DC/AC voltage:
4.10.1 Move the rotary switch to the position.
4.10.2 Connect the red test lead to the V jack and the
black lead to the COM jack.
4.10.3 Connect the leads in parallel with the circuit under
test.
4.10.4 The measured voltage will be displayed. For DC
measurement, the polarity of the red lead will be
indicated.
