NOTE.
If you ordered a power cord, it will come with a ferrite core. Install the
ferrite core as shown in the instructions with which it was shipped.
The instrument operates from an external AC adapter and has the following power
requirements:
A single-phase power source with one current-carrying conductor at or near
earth-ground (the neutral conductor).
The power source frequency must be 50 or 60 Hz, and a operating voltage
range must be from 100 to 240 VAC, continuous.
WARNING.
To reduce risk of fi re and shock, make sure the mains supply voltage
fl uctuations do not exceed 10% of the operating voltage range.
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.
NOTE.
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 unit to an authorized service center for
repair.
