Measuring AC Voltage
Set up your clamp meter to measure AC voltage as shown in
Figure 2- 5. Probe the test points, and read the display.
Figure 2-4 AC voltage display
NOTE
Reversing the leads will produce a negative reading, but it will not damage
the clamp meter.
NOTE
For U1193A and U1194A models:
AC voltage measurements measured with this clamp meter are returned
as true RMS (root mean square) readings. These readings are accurate for
sinusoidal waves. For non-sinusoidal waveforms, please refer to the
“Specification Assumptions” on page 64.
NOTE
Press to measure the frequency of the AC voltage source (U1192A,
U1193A, and U1194A models only). See “Measuring Frequency” on
page 50 to learn more.
