CAUTION
To avoid damaging this multimeter, do not exceed the rated input limit.
NOTE
Voltages above 300 VAC may be measured only in circuits that are isolated from mains.
However, transient overvoltages are also present on circuits that are isolated from mains.
The Agilent U3401A is designed to safely withstand occasional transient overvoltages up to
2500 V PEAK. Do not use this multimeter to measure circuits where transient overvoltages
could exceed this level.
