Operating Precautions
5
Follow these precautions to ensure safe operation and to obtain the full benefits of the vari-
ous functions.
Before using the instrument the first time, verify that it operates normally to ensure that the
no damage occurred during storage or shipping. If you find any damage, contact your
dealer or Hioki representative.
Operating temperature & humidity: 0 to 40°C (32 to 104°F), 80%RH or less (non-condensating)
Operating temperature & humidity for guaranteed accuracy: 23 ± 5°C (73 ± 9°F), 80%RH or less
Operating Precautions
Preliminary checks
Before using the instrument, make sure that the insulation on the
test leads is undamaged and that no bare conductors are improp-
erly exposed. Using the instrument in such conditions could
cause an electric shock, so contact your dealer or Hioki represen-
tative for repair.
Installing the instrument
Avoid the following locations that could cause an accident or damage to the instrument.
Exposed to direct sunlight
Exposed to high tempera-
ture
In the presence of corro-
sive or explosive gases
Exposed to liquids
Exposed to high humidity
or condensation
Exposed to strong electro-
magnetic fields
Near electromagnetic radi-
ators
Exposed to high levels of
particulate dust Subject to vibration
Installing the instrument
• Vents must not be obstructed.
• The instrument should be operated
only with the bottom side downwards.
• Do not place on an unstable stand or
on an incline.
10 cm or more
Ventilation holes

Operating Precautions
6
Handling the instrument
To avoid electric shock, do not remove the instrument's case. The
internal components of the instrument carry high voltages and
may become very hot during operation.
To avoid damage to the instrument, protect it from physical shock when
transporting and handling. Be especially careful to avoid physical shock
from dropping.
To avoid problems with battery operation, remove the batteries from the
instrument if it is to be stored for a long time.
Handling the CD
• Always hold the disc by the edges, so as not to make fingerprints on
the disc or scratch the printing.
• Never touch the recorded side of the disc. Do not place the disc
directly on anything hard.
• Do not wet the disc with volatile alcohol or water, as there is a possibil-
ity of the label printing disappearing.
• To write on the disc label surface, use a spirit-based felt pen. Do not
use a ball-point pen or hard-tipped pen, because there is a danger of
scratching the surface and corrupting the data. Do not use adhesive
labels.
• Do not expose the disc directly to the sun's rays, or keep it in condi-
tions of high temperature or humidity, as there is a danger of warping,
with consequent loss of data.
• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
cloth, or use a CD cleaner. Always wipe radially from the inside to the
outside, and do no wipe with circular movements. Never use abra-
sives or solvent cleaners.
• Hioki shall not be held liable for any problems with a computer system
that arises from the use of this CD, or for any problem related to the
purchase of a Hioki product.

1.1 Product Overview

Chapter 1 Overview
The 3145-20 NOISE HiLOGGER is the ideal measuring instrument for
measuring current on lines which can easily become channels for noise
penetration, such as communication lines, electric power cords and
ground lines which connect to electronic equipment.
By clamping with the 9754 CLAMP ON NOISE SENSOR the 3145-20
detects noise without touching the sample. Therefore it can perform
measurements on instruments in their normal operational state, without
worry of communication malfunction due to probe contact, or electrical
shock or electrical short circuit accidents from electrical lines. Further-
more, it can reliably detect sudden surges which may occur unexpect-
edly, such as thunder surges and open-close surges.
With the use of the logging function, long term or cyclic noise level fluctu-
ations can be understood. Recorded data is shown on the instrument's
color LCD display as a chronological graph. Additionally, transferring
data to a PC and checking the chronological graph can be done using
the "DATA VIEWER for 3145" software on the included CD. This can be
useful for examining noise counter-measures after an occurance of
noise interference.

1.2 Features
Simple and safe measurements
With the use of the optional Clamp on Noise Sensor, noise can be measured on
power cords, various communications lines, and ground lines without making con-
tact or grounding.
Wide frequency range (5 kHz - 100 MHz)
The instrument is effective for detecting switching regulator noise, inverter noise,
electrostatic discharge noise, and FM broadcast wave noise.
Surge detection
The instrument detects lightning surges, power-related switching surges, and
electrostatic discharge noise.
Logging measurement function
Long-term and cyclic noise levels can be ascertained, and the times at which the
noise and interference occured can be investigated.
Alarm function and event mark function
An alarm level for alarm output can be set, and event marking can be enacted at
the time an event occurs.
Remote measuring with an HTTP server
Remote control of the instrument's settings, data acquisition and data display can
be performed using a web-based browser such as IE.
A portable, dedicated noise measurement instrument intended for on-
site use
The instrument supports two types of power sources, recharchable batteries
designed for on-site use, and an AC adaptor power supply for long period obser-
vation and remote measuring. The recharchable battery can also be used as a
backup in case of power failure.

1.3 Measuring Principle

Chapter 1 Overview
The instrument separates input noise waves into frequency bandwidths using a seven
band-pass filter (7 frequency waves) and detects and displays peak values (Peak to Peak
values) for each respective frequency range.

This instrument has two measuring modes, monitor and logging.
Monitor measurement
Logging measurement
1.3.1 Monitor Measuring and Logging Measuring
The current input levels of each frequency are displayed
as a bar graph and numbers.
Noise measurement can be made easily in the tester in-
terval.
With the logging measurement function the change over
time of the noise level of each frequency band is record-
ed. When and at what frequency band
noisepenetratedcan beeasilyascertained. Thetime that
the interference occured and the type of noise that oc-
cured at that time can be understood.
The peak value within the manually set recording interval
segmentis savedin theinternalmemory anddisplayed in
a chronological bar graph. The recording interval can be
set between 1 second and 60 seconds.
Measurement data can be saved on PC card.
Daily and weekly changes in the noise can beob-
served using the "DATA VIEWER for 3145" soft-
ware on the included CD to conduct daily and
weekly calculation displays of the recorded data.

1.3 Measuring Principle
11
1
Chapter 1 Overview
Simultaneous noise measurement of each frequency bandwidth from 10 kHz
to 100 MHz.
Noise exists in a wide bandwidth and its frequency differs depending on
its cause. With this instrument a wide bandwidth of noise can be
checked all at once.
Peak-detection function for capturing surge events
Surge incidents of noise such as lightning surges and electrostatic dis-
charge noise sometimes occur. Using the instrument's peak function,
incidents of surge noise can be accurately captured.
