2.2 Voltage Selection

Voltage selection is required only between low (nominal 100-120 V) and high
(nominal 200-240 V) ranges. There is no distinction between 50 and 60 Hz
supplies. Refer to

section 1.3.1 on page 1-6

for specific power requirements.

CAUTION

Verify that the correct fuse is in place by visually
inspecting the fuse for the proper rating. Use of an
improperly sized fuse may create a safety hazard.

For 100-120 V(ac) operation use a 3/8 Amp Type T fuse.
For 200-240 V(ac) operation use a 3/16 Amp Type T fuse.

NOTE: These instruments are designed to operate between 90 V(ac) and

132 V(ac) on Low Range and between 180 V(ac) and 264 V(ac) on High
Range.

WARNING

This instrument has line voltage present on the
primary circuits whenever it is plugged into a main
power source.

Potentially lethal voltages are present when the line
cord, system I/O or aux I/O are connected.

This instrument must be disconnected from the main
power source before inspecting or replacing the fuse.
