Measuring AC Voltage

The AC voltage measurement function has the following

features:

• Five ranges to select: 100 mVrms, 1 Vrms, 10 Vrms, 100

Vrms, and 250 Vrms or, auto- range.

• Measures the AC -coupled true rms.

• Measures within the stipulated accuracy at a crest factor

of a maximum of 5:1 (full scale).

• Input impedance is 1 MΩ ± 2% in parallel with less than

120 pF capacitance on all ranges.

Make the connection as shown below.
