Power-up
Line power connection
Follow the procedure below to connect the Series 3700 to line power and turn
on the instrument. The Series 3700 operates from a line voltage of 100V to
240V at a frequency of 50Hz or 60Hz. Line voltage is automatically sensed.
There are no switches to set. Make sure the operating voltage in your area is
compatible.
WARNING
The power cord supplied with the Series 3700 contains a
separate ground wire for use with grounded outlets. When
proper connections are made, instrument chassis is
connected to power line ground through the ground wire in
the power cord. Failure to use a grounded outlet may result
in personal injury or death due to electric shock.
CAUTION
Operating the instrument on an incorrect line voltage may cause
damage to the instrument, possibly voiding the warranty.
1. Before plugging in the power cord, make sure that the front panel power
switch is in the off (O) position. See
Rear panel summary
(on page 3-1) for
connector location.
2. Connect the female end of the supplied power cord to the (5) Power
Connector (AC receptacle) on the rear panel. Connect the other end of the
power cord to a grounded AC outlet.
3. Turn on the instrument by pressing the front panel power switch to the on (I)
position. See
Front panel introduction
(on page 2-1) for switch location.
Line frequency
NOTE
Line frequency only applies to models with a DMM installed.
The Series 3700 will operate at line frequencies of either 50Hz or 60Hz. The line
frequency is auto-detected at startup.
Use the localnode.linefreq bus command to see the line frequency. For
example:
print(localnode.linefreq)
