Measuring Voltage
3.2 Measuring Voltage
AC/DC voltage measurement and measurement using the AC and
DC automatic judgment (only the DT4253, DT4254, DT4255, and
DT4256) can be performed. Furthermore, the maximum, minimum,
and average values of the measured values can be checked. (p. 66)
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-ranging function of this instrument automatically selects
the optimum measurement range. To change the range arbitrarily,
use the manual range. (p. 59)
Measuring AC voltage
Measure the AC voltage. Measure the frequency simultaneously.
The measured value is a true RMS. (p. Appx.1)
