5.3 Voltage and Frequency Measurements
1.
Refer to the Fig. 5-1 below.
2.
Set the function switch to one of the following positions:
•
(
VDC) or (VAC) for high voltage measurements.
•
(milli-volts) for low voltage measurements (use MODE to select AC or
DC).
•
for voltage measurements using the meter’s low input impedance
mode. The
LoZ
indicator will be displayed (use
to select AC or DC).
3.
Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive terminal.
4.
For
mV
and
LoZ
measurements use the
button to select AC or DC
measurement:
•
The
indicator shows for AC measurements.
•
The
indicator shows for DC measurements.
5.
Connect the probe leads in parallel to the part under test.
6.
Read the voltage value on the display.
7.
For AC Voltage Measurements, the Frequency (Hz) of the measured voltage
appears on the smaller, secondary display digits above the primary voltage
reading. To display only the Frequency, navigate to the
menu icon using the
arrow buttons and enable (or disable) the mode by pressing
OK
.
