Safety Considerations
CAUTION
Read the information below before using this instrument.
The following general safety precautions must be observed during all
phases of operation, service, and repair of this instrument. Failure to
comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards for design, manufacture, and intended
use of the instrument. Agilent Technologies assumes no liability for the
customer’s failure to comply with these requirements.
• Disconnect circuit power and discharge all high-voltage capacitors
before testing.
• When measuring in-circuit components, first de-energize the
circuits before connecting them to the test leads.
• This device is for indoor use at altitudes of up to 2000 m.
• Always use the specified battery type (listed in “Product
Characteristics" on page 74). The power for the meter is supplied
with a single standard 9 V battery. Observe the correct polarity
markings before you insert the battery to ensure proper insertion of
the battery in the meter.
• Line operation is also possible using a 12 V AC to DC adapter. If a
power adapter is selected, please be sure it meets the safety
requirements of a relevant IEC standard.

WARNING
• Use this meter only as specified in this manual; otherwise, the
protection provided by the meter may be impaired.
• Do not use the meter if it is damaged. Before you use the meter,
inspect the case. Look for cracks or missing plastic. Pay
particular attention to the insulation surrounding the connectors.
• Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged test leads
before you use the meter.
• Do not operate the meter around explosive gas, vapor, or wet
environments.
• Never use the meter in wet conditions or when there is water on
the surface. If the meter is wet, ensure that the meter is dried only
by trained personnel.
• When servicing the meter, use only the specified replacement
parts.
• When using the probes, keep your fingers behind the finger
guards on the probes.
• Connect the common test lead before you connect the live test
lead. When you disconnect the leads, disconnect the live test lead
first.
U1731C/U1732C/U1733C User’s Guide V
• Remove the test leads from the meter before you open the battery
cover.
• Do not operate the meter with the battery cover or portions of the
cover removed or loosened.
• To avoid false readings, which may lead to possible electric shock
or personal injury, replace the battery as soon as the low battery
indicator appears and flashes.

Preparing Your LCR Meter
CAUTION
Check the shipment
When you receive your LCR meter, check the shipment
according to the following procedure.
1 Inspect the shipping container for damage. Signs of
damage may include a dented or torn shipping container
or cushioning material that indicates signs of unusual
stress or compacting. Save the packaging material in case
the LCR meter needs to be returned.
2 Carefully remove the contents from the shipping
container, and verify that the standard accessories and
your ordered options are included in the shipment
according to the standard shipped items list found in the
printed copy of the U1731C/U1732C/U1733C Quick Start
Guide.

Install the battery
Your LCR meter is powered by a single 9 V alkaline battery
(included with the shipment). When you receive your LCR
meter, the 9 V alkaline battery is not installed.
Use the following procedure to install the battery.
Before you proceed with the battery installation, remove all cable
connections to the terminals and ensure that the LCR meter is turned
OFF. Use only the battery type specified in “Product Characteristics” on
page 74.
1 Introduction
WARNING
Preparing Your LCR Meter
1 Open the battery cover. Lift the tilt stand. Loosen the
screw with a suitable Phillips screwdriver and remove the
battery cover as shown in Figure 1-1.
2 Insert the battery. Observe the proper battery polarity.
The terminal ends of the battery are indicated inside the
battery compartment.
3 Close the battery cover. Place the battery cover back in
its original position and tighten the screw.

Figure 1-1 Installing the batteries
The battery level indicator in the lower right- hand corner of
the display indicates the relative condition of the battery.
Table 1- 1 describes the various battery levels the indicator
represents.
To avoid false readings, which could lead to possible electric shock
or personal injury, replace the battery as soon as the low battery
indicator appears. Do not discharge the battery by shorting the
battery or reverse the battery polarity.

Preparing Your LCR Meter
To power OFF your LCR meter, press the power- on button
again.
You can change the power-on behavior of your LCR meter for subsequent
power cycles. See “Changing the initial power-on behavior” on page 54 for
more information on changing the LCR meter’s power-on setting.
Automatic Power-Off (APO)
Your LCR meter automatically turns off after 5 minutes
(default) if no keys are pressed. Pressing any key will turn
the LCR meter back on after it is powered off automatically.
The annunciator is shown on the bottom left of the
display when the APO function is enabled.
• To change the timeout period or completely disable the APO function,
refer to “Changing the auto power-off and backlight timeouts” on
page 71.
• If an
external power adapter is used, the APO function will be disabled.
Enabling the backlight
If viewing the display becomes difficult in low- light
conditions, press for more than 1 second to activate the
LCD backlight.
To conserve battery life, a user- adjustable timeout controls
how long the backlight stays on. The default timeout is 30
seconds.
• To change the timeout period or completely disable the backlight, refer
to “Changing the auto power-off and backlight timeouts” on page 71.
• If an
6 U1731C/U1732C/U1733C User’s Guide
external power adapter is used, the backlight timeout will be disabled.

Auto
Range
Pressing switches the LCR meter between manual and
autoranging. It also cycles through the available LCR meter
ranges when manual ranging is enabled.
Autoranging is convenient because the LCR meter
automatically selects an appropriate range for sensing and
displaying each measurement. However, manual ranging
results in better performance, since the LCR meter does not
have to determine which range to use for each measurement.
In autorange, the LCR meter selects the lowest range to
display the highest available precision (resolution) for the
input signal. If manual range is already enabled, press
for more than 1 second to enter the autoranging mode.
If autoranging is enabled, press to enter the manual
range mode.
Each additional press of sets the LCR meter to the next
higher range, unless it is already in the highest range, at
which point the range switches to the lowest range.

perform data logging operations, and transfer the contents of
your LCR meter’s memory to a PC.
Ensure that the Agilent logo on the U5481A IR- USB cable
(purchased separately) connected to the LCR meter is facing
