Starting up your instrument
The following topics describe how to power your instrument on and off, place the instrument in
standby, configure the line frequency, and replace the line fuse.
Procedure
The Series 3700A operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz or 60 Hz. At
the factory, each Series 3700A is configured to match the power line frequency appropriate for your
country (either 50 Hz or 60 Hz). Make sure the operating voltage in your area is compatible.
Follow the procedure below to connect the Series 3700A to line power and turn on the instrument.
Operating the instrument on an incorrect line voltage may cause damage to the instrument,
possibly voiding the warranty.
On some sensitive or easily damaged devices under test (DUTs), the instrument power-up and
power-down sequence can apply transient signals to the DUT that may affect or damage it. When
testing this type of DUT, do not make final connections to it until the instrument has completed its
power-up sequence and is in a known operating state.
When testing this type of DUT, disconnect it from the instrument before turning the instrument off.
To prevent any human contact with a live conductor, connections to the DUT must be fully insulated
and the final connections to the DUT must only use safety-rated safety jack socket connectors that
do not allow bodily contact.
