The AC/DC adapter has an auto–ranging line voltage input – be sure the
supply voltage is within the specified range.
The AC/DC adapter is for indoor use only.
Never use a modified or damaged charger. Use the original AC–DC
adapter ONLY.
The AC/DC adapter is designed for use in Installation Category II and
Pollution Degree 2 per IEC 61010-1.
The instrument can operate with mains supply voltage fluctuations
up to ± 10% of the nominal voltage.
If charging batteries externally, use the optional external charger available
from Keysight, or another SMBus charger of level II or higher.
Never use a non–SMBus charger because the battery issues commands
over the SMBus to the charger to control the charge rate and voltage.
Never use a modified or damaged charger.
