Inputs may be connected to
mains (up to 300 VAC) under
Category II overv oltage conditions.
WARNING
Main Power and Test Input Disconnect: Unplug instrument 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.
WARNING
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.
WARNING
Front/Rear Switch: Do not
change the position of the
Front/Rear switch on the front
panel while signals are present on
either the front or rear set of terminals. The switch is not intended
as an active multiplexer. Switching while high voltages or currents are present may cause
instrument damage and lead to
the risk of electric shock.
WARNING
IEC Measurement Category II. The
HI and LO input terminals may be
connected to mains in IEC Category II installations 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. See
"IEC Measurement Category II
Overvoltage Protection" on the
following page for further information.
WARNING
Protection Limits: To avoid instrument damage and the risk of electric shock, do not exceed any of
the Protection Limits defined in
the following section.
34410A/11A/L4411A User’s Guide 3
Protection Limits
The A gilent 3441 0A/11A and L4411A D igital
Multimeters provide protection circuitry to
prevent damage to the instrument and to
protect against the danger of electric shock,
provided the Protection Limits are not
exceeded. To ensure safe operation of the
instrument, do not exceed the Protection
Limits shown on the front and rear panel,
and defined below:
Note: The front-panel terminals are shown
above. The rear-panel terminals are identical. The Front/Rear switch selects the terminal set to be used. Do not operate this
switch while signals are present on the
front or rear terminals. The current-protec-
tion fuse is on the rear panel.
Input Terminal Protection
Limits
Protection Limits are defined for the input
terminals:
Main Input (HI and LO) Terminals. The HI
and LO input terminals are used for voltage,
resistance, capacitance, and diode test
measurements. Two Protection Limits are
defined for these terminals:
HI to LO Protection Limit. The Protection
Limit from HI to LO ("A" in the figure at
left) is 1000 VDC or 750 VAC, which is
also the maximum voltage measurement.
This limit can also be expressed as 1000
Vpk maximum.
LO to Ground Protection Limit. The LO
input terminal can safely "float" a maximum of 500 Vpk relative to ground. T his is
Protection Limit "B" in the figure.
As is implied by the above limits, the Protection Limit for the HI input terminal is a maximum of 1500 Vpk relative to ground.
Current Input Terminal. The current input
("I") terminal has a Protection Limit of 3A
(rms) maximum current flowing from the LO
input terminal. This is Protection Limit "C"
in the figure. Note that the current input terminal will be at approximately the same
voltage as the LO terminal.
Note: The current-protection circuitry
includes a fuse on the rear panel. To maintain protection, replace this fuse only with a
fuse of the specified type and rating.
Sense Terminal Protection
Limits
The HI and LO sense terminals are used
only for four-wire resistance and temperature measurements ("
tion Limit is 200 Vpk for all of the terminal
pairings ("D" in the figure):
LO sense to LO input.
HI sense to LO input.
HI sense to LO sense.
Ω 4W"). The Protec-
Note: The 200 Vpk limit on the sense terminals is the Protection Limit. Operational
voltages in resistance measurements are
much lower — less than 10 V in normal
operation.
IEC Measurement Category II
Overvoltage Protection
To protect against the danger of electric
shock, the A gi lent 34410A/11A and L4411A
Digital Multimeters provide overvoltage protection for line-voltage mains connections
meeting both of the following conditions:
The HI and LO input terminals are connected to the mains under Measurement
Category II conditions, defined below,
and
The mains are limited to a maximum line
voltage of 300 VAC.
IEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include
most small appliances, test equipment, and
other devices that plug into a branch outlet
or socket. The 34410A/11A and L4411A
may be used to make measurements with
the HI and LO inputs connected to mains in
such devices, or to the branch outlet itself
(up to 300 VAC). However, the 34410A/11A
and L4411A may not be used with its HI and
LO inputs connected to mains in permanently installed electrical devices such as
the main circuit-breaker panel, sub-panel
disconnect boxes, or permanently wired
motors. Such devices and circuits are subject to overvoltages that may exceed the
protection limits of the 34410A/11A and
L4411A.
Note: Voltages above 300 VAC may be measured only in circuits that are isolated from
mains. However, transient overvoltages are
also present on circuits that are isolated
from mains. The Agilent 34410A /11A and
L4411A are designed to safely withstand
occasional transient overvoltages up to
2500 Vpk. Do not use this equipment to
measure circuits wh ere transient overvoltages could exceed this level.

Other Basics of Operation
This section covers basic troubleshooting and general use.
If the Multimeter Does Not Turn On
Use the following steps to help solve problems you might encounter when
turning on the multimeter. If you need more help, see the Service Guide for
instructions on returning the multimeter to Agilent for service.
1 Verify that there is ac power to the multimeter.
First, verify that the multimeter’s Power switch is in the “On” position. Also,
make sure that the power cord is firmly plugged into the power module on the
rear panel. You should also make sure that the power source you plugged the
multimeter into is energized.
2 Verify the power–line voltage setting.
The line voltage is set to the proper value for your country when the
multimeter is shipped from the factory. Change the voltage setting if it is not
correct. The settings are: 100, 120, 220, or 240 Vac (for 230 Vac operation, use
the 220 Vac setting).
See “To Replace the Power-Line Fuse (34410A/11A)” on page 32 if you need to
change the line–voltage setting.
Quick Start 1
3 Verify that the power–line fuse is good.
The multimeter is shipped from the factory with a power–line fuse installed.
The supplied fuse is a 250 mAT, 250V, slow–blow, 5x20mm fuse, Agilent part
number 2110–0817. If you determine that the fuse is faulty, replace it with one
of the same size and rating.
See “To Replace the Power-Line Fuse (34410A/11A)” on page 32 if you need to
replace the power–line fuse.
The current input path is also fused. The supplied fuse is a 3 AT, 250V,
slow–blow, 5x20mm fuse, Agilent part number 2110–0780, and is housed in
a standard screw–in fuse holder on the left side of the rear panel. If you
determine that the fuse is faulty, replace it with one of the same size and
rating.
