Measurement Category III

Prevention of fire or injury:

• Use only the designated AC adapter and test leads

supplied with the instrument.

• Observe all ratings and markings of the instrument

before connecting to the instrument.

• When performing measurement, ensure that the

right safety and performance ratings of instrument

and accessories are used.

• Connect the scope probe or test leads to

instrument before connecting to any active circuit

for testing. Before disconnecting the active circuit

from instrument, remove scope probe or test leads

from active circuit.

• Do not connect the ground wire to voltages higher

than 42 Vpeak (30 Vrms) from earth ground.

WARNING

Maximum Input Voltages

Maximum Floating Voltage

• From any terminal to ground — 300 Vrms CAT III

(up to 400 Hz)

• Input CH1 and CH2 direct (1:1 Probe) — 300 V CAT III

• Input CH1 and CH2 via 1:10 Probe — 600 V CAT III

• Input CH1 and CH2 via 1:100 Probe — 600 V CAT III

• Meter Input — 300 V CAT III, 600 V CAT II

• Scope Input — 300 V CAT III

• Voltage ratings are Vrms (50 Hz - 60 Hz) for AC sine

wave and VDC for DC applications.

• Do not expose the circuit or operate the instrument

without its cover or while power is being supplied.

• Do not use exposed metal BNC or banana plug

connectors, use only the insulated voltage probes,

test leads and adapters that come with the

instrument.

• Do not supply any voltage when measuring

resistance or capacitance in meter mode.

• Do not operate the instrument if it does not operate

properly, have the instrument inspected by qualified

service personnel.

• Do not operate the instrument in wet or damp

environments.

• Do not operate the instrument in any environment

in a risk of explosion.

• Maintain a clean and dry condition to the

instrument’s surface.

Prevention of electro-static discharge

• Electro-static discharge (ESD) can result in damage

to the components in the instrument and

accessories.

• Select a static-free working location when installing

and removing sensitive components.

• Handle sensitive components to the minimum

extent possible. Do not allow contacts between

components and exposed connector pins.

• Transport and store in ESD preventive bag or

container that protects sensitive components from

static electricity.

A new rechargeable battery comes in a discharged condition and must be charged

before use (refer to the U1602A and U1604A User's and Service Guide for charging

instructions). Upon initial use (or after a prolonged storage period) the

rechargeable battery may require three to four charge/discharge cycles before

achieving maximum capacity. To discharge, simply run the oscilloscope using the

Introduction

This quick start guide provides the basic information, front panel functions

and general specifications of Agilent U1600A Series handheld digital

oscilloscopes. The U1600A Series can also function as a digital multimeter

(DMM) and data logger. With its 4.5- inch LCD color display, it is capable of

clearly distinguishing waveforms from two channels. The U1600A Series

handheld digital oscilloscopes are high performance troubleshooting tools in

multi- industrial automation, process control, facility maintenance and

automotive- service industries. The U1600A Series comprises two models:

U1602A and U1604A, with 20 MHz and 40 MHz bandwidths, respectively. Both

models are dual- channel scopes with real- time sampling rate of up to 200

MSa/s. Users can use the Dual Waveform Math (DWM) and Fast Fourier

Transform (FFT) functions (in U1604A) to perform a quick waveform analysis

in both time and frequency domain. The U1600A Series with built- in 6000-

count resolution and true RMS comes with an auto range function that allows

users to perform quick and accurate DMM measurements. Additionally, with

data logger function, users can perform automatic data logging for all DMM

measurements.

To Charge a Battery

Upon delivery of the unit, the rechargeable

battery is required to be fully charged for

approximately 25 hours with the

designated Agilent AC adapter. Ensure that

you have the correct line power cord. The

AC adapter converts input line voltages

ranging from 100 VAC to 240 VAC to

output voltage 12 VDC.

Input: 100 V – 240 VAC

Output: 12 VDC, 2 A,

50/60 Hz

To Power On the Handheld Scope

To turn on or off the scope, press and hold the

power switch button for three seconds. A

basic self-test shall be executed

automatically upon power up. The scope will

be loaded with the last configuration setup of

the scope.
