Connect Power and I/O Cables
Connect the power cord and LAN, GPIB, or USB cable as desired. After you turn on the instrument (as
described below), the instrument will run a power-on self test and then display a message about how to
obtain help, along with the current IP address. It also displays the GPIB address (if applicable).
The instrument's default measurement function is DC Voltage (DCV), with autoranging enabled.
Power Switch
Press the power switch in the lower left corner of the front panel. If the instrument does not turn on, verify
that the power cord is firmly connected and that the fuse is good and the line voltage selector is set cor-
rectly, as described above. Also make sure that the instrument is connected to an energized power
source. If the LED below the power switch is off, there is no AC mains power connected. If the LED is
amber, the instrument is in standby mode with AC mains power connected, and if it is green, the instru-
ment is on.
In certain circumstances, the amber LED can come on even if the wrong line voltage is selected. In this case,
the instrument may not power on.
If the power-on self test fails, the display shows Error in the upper right corner. It also displays a message
describing the error. See
Introduction
for instructions on returning the instrument for service.
To turn off the instrument, press and hold the power switch for about 500 ms. This prevents you from acci-
dentally turning off the instrument by brushing against the power switch.
If you turn off the instrument by disconnecting power (this is not recommended), the instrument turns on as
soon as you re-apply power. You will not need to press the power switch.
