Safety Summary
Do not defeat power cord safety ground feature.
Plug in to a grounded (earthed) outlet. Do not use
product in any manner not specified by the
manufacturer.
Do not install substitute parts or perform any
unauthorized modification to the product. Return
the product to Agilent Technologies or a
designated repair center for service to ensure that
safety features are maintained.
WARNING
A WARNING notice denotes a hazard. It calls
attention to an operating procedure, practice, or
the like that, if not correctly performed or adhered
to, could result in personal injury or death. Do not
proceed beyond a WARNING notice until the
indicated conditions are fully understood and met.
CAUTION
A CAUTION notice denotes a hazard. It calls
attention to an operating procedure, practice, or
the like that, if not correctly performed or adhered
to, could result in damage to the product or loss
of important data. Do not proceed beyond a
CAUTION notice until the indicated conditions are

Risk of electric shock
Refer to manual for additional safety
information.
CAT II (300 v) IEC Overvoltage Category II.
Inputs can be connected to mains (up to 300
VAC) under Category II overvoltage conditions.
WARNING
Main Power and Test Input Disconnect: Unplug
product from wall outlet, remove power cord, and
remove all probes from all terminals before
servicing. Only qualified, service-trained
personnel should remove the cover from the
instrument.
Line and Current Protection Fuses: For
continued protection against fire, replace the line
fuse and the current-protection fuse only with
fuses of the specified type and rating.
IEC Overvoltage Category II. The HI and LO
input terminals may be connected to mains under
IEC Category II overvoltage conditions for line
voltages up to 300 VAC. To avoid the danger of
electric shock, do not connect the inputs to mains
for line voltages above 300 VAC. Connect to
mains only at an outlet, or in a device connected
to such an outlet, on a branch circuit protected by
a circuit breaker. See "Safety Notices" in the
Agilent 34405A User's and Service Guide for
further information.
Protection Limits: To avoid instrument damage
and the risk of electric shock, do not exceed any
of the protection limits indicated on the terminal
panel and defined in the Agilent 34405A User's
and Service Guide.
ADDITIONAL SAFETY INFORMATION
For further information, refer to the "Safety
Notices" section in the Agilent 34405A User's and
Service Guide.

Press the Power (on/off) switch:
The front-panel display illuminates while the
multimeter performs its power-on self-test.
Following self-test, the multimeter defaults to
DC voltage measurements.* Typical display:
Measurements are shown in the primary
display (bottom left) and the measurement
range is shown in the secondary display (top
right).
*You can set the multimeter to return to the last
power-down state when power is applied. See the
34405A User's and Service Guide for details.

5½ digit readings have the best accuracy and
noise rejection. 4½ digit readings provide for
faster readings.

8. Using the Secondary Display
When making measurements, the secondary display allows you to show the measurement
range (for most measurement functions) or to select a predefined secondary
measurement function. You may have already noticed the secondary display showing
Auto for autorange when changing measurement functions:
As another example, a typical primary display showing ACV and a secondary display
showing the measured frequency of the input signal is:
The secondary display is based on the selected primary measurement function and how
many times you press:

9. Using the Math Functions
The 34405A has these math functions: Null, dBm, dB, Min/Max, Limit and Hold. As an
example, Null is commonly used to eliminate the effects of test leads from
measurements. Connect the test leads together and to the HI and LO input terminals.
Select resistance measurements by pressing:
The display should be showing the measured test lead resistance. Typical display:
To select the math Null function, press:
The Null value is measured and subtracted from all resistance readings in the primary
measurement display. The Null value is shown in the secondary display and the Null and
Ref Value annunciators are on. Typical display:
Pressing the same math key again turns the math function off.
