Description
First, this command resets all ac voltage measurement parameters and
trigger parameters to their default values. Then, it configures the meter for
ac voltage measurements and immediately triggers a measurement. The
results are sent directly to the instrument output buffer.
The maximum range parameter is 1000 V, which is set by
MAX. However, the SAFETY LIMIT on the front and rear
HI/LO input terminals is 750 VAC (rms). The rms voltage is
waveform dependent. A sine wave is limited to 750 VAC
(rms), but a 1000 Vpk square wave is safe. Connections to
AC MAINS are further limited to CAT II (300V). See the
"Safety Information" section in the Agilent
34410A/11A/L4411A User's Guide for a complete
discussion of the safety features, and the safe operation of
this instrument.
