Programmers Manual
A W Caution statement identifies conditions or practices that could result in damage to
the Meter or equipment to which it is connected.
To avoid electric shock, personal injury, or death, carefully read
the information under "Safety Information" before attempting to
install, use, or service the Meter.

Local and Remote Operation

When the Meter is operated from a host, it is said to be operated remotely. When operated
from the front panel, it is said to be operated locally.
Most operations that can be performed locally can also be performed remotely over the
remote interface. Some operations, like setting communications parameters for the
RS-232 interface, and addressing the Meter for IEEE 488 operations can only be set
through the front panel.
To avoid electric shock, turn off the signal source to the Meter
before touching the test leads. The front panel display may not
indicate the true input voltage while in remote mode. Always
assume lethal voltages exist on the front-panel inputs.
