Measuring Voltage
3.2 Measuring Voltage
The AC/DC voltage can be measured. Furthermore, the AC
frequency and duty ratio can be checked.
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. 7).
The autoranging function of this instrument automatically selects the
optimum measurement range. To change the range arbitrarily, use
the manual range. (p. 45)

The AC voltage is measured.
The measured value is an average
rectifying RMS indication (DT4211)
or true RMS indication (DT4212).
(p. Appx.1)
When the Hz/% key is pressed, the
frequency and duty ratio can be
measured. (p.
