Applying Power; Power-On Self-Test; Power-On State - Keysight Technologies 3458A Guide D'utilisation

2 Getting Started

Applying Power

To turn on the multimeter, depress the front panel Power switch. If the multimeter
does not appear to turn on, verify that the multimeter is connected to line power.
If line power is not the problem, remove the power cord and check the line power
fuse and the line voltage selection switch settings.

Power-on self-test

When power is applied, the multimeter performs a limited power-on self-test. This
test verifies that the multimeter is operating but does not necessarily verify that
measurements will be accurate.

Power-on state

When the power-on self-test is finished, the multimeter beeps once,
automatically triggers, automatically selects the range, and performs DC voltage
measurements. Also, the multimeter has set many of its commands to predefined
power-on values as shown in
