Power Requirements
Power connector
The instrument has the following power requirements:
A single-phase power source with one current-carrying conductor at or near
earth-ground (the neutral conductor).
NOTE.
Systems with both current-carrying conductors live with respect to ground
(such as phase-to-phase in multiphase systems) are not recommended as power
sources.
The mains supply frequency must be 50 or 60 Hz.
The mains supply voltage must be in the range from 100 to 240 V
AC
.
WARNING.
To reduce risk of
fi
re and shock, ensure the mains supply voltage
fl
uctuations do not exceed 10% of the operating voltage range.
Fuses
Only the line conductor is fused for over-current protection. The fuse is internal
and not user replaceable. Do not attempt to replace the fuse. If you suspect the
fuse has blown, return the instrument to an authorized service center for repair.
Batteries
The instrument does not contain any user-replaceable batteries.
