Measuring Voltage
3.2 Measuring Voltage
AC voltage, DC voltage, synthesized voltage of DC and AC, and
voltage of AC and DC components can be measured. Furthermore,
the maximum, minimum, and peak (instantaneous) values of
measured values can be checked. (p. 61)
Before measurements
WARNING
If the instrument is used in locations where the rating
indicated on the instrument or probes is exceeded,
the instrument may be damaged resulting in personal
injury. Do not use the instrument in such locations.
See “Measurement categories” (p. 9).
The auto-range function of this instrument automatically selects the
optimum measurement range. To change the range arbitrarily, use
the manual range. (p. 55)

Measure the AC voltage.
Measure the frequency simultaneously.
The measured value is a true RMS.
(p. Appx.1)
If the input voltage is lower
than each range’s accuracy
guarantee range, the instrument
may display zero.
Choose an appropriate range for
the input voltage to measure it.
