CAUTION
• If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment could be impaired.
• Do not install substitute parts or perform any unauthorized modification to the
instrument.
• Service instructions, when applicable, are for trained service personnel. To avoid
the risk of electric shock, do not perform any work on the instrument unless
qualified to do so. For any problem or question regarding this instrument, contact
Olympus or an authorized Olympus representative.
• Do not touch the connectors directly by hand. Otherwise, a malfunction or electric
shock may result.
• Do not allow metallic or foreign objects to enter the device through connectors or
any other openings. Otherwise, a malfunction or electric shock may result.
Battery Precautions
• Before disposing of a battery, check your local laws, rules, and regulations, and
follow them accordingly.
• When lithium-metal batteries are used, transportation of the batteries is regulated
by the United Nations under the United Nations Recommendations on the
Transport of Dangerous Goods. It is expected that governments,
intergovernmental organizations, and other international organizations shall
conform to the principles laid down in these regulations, thus contributing to
worldwide harmonization in this field. These international organizations include
the International Civil Aviation organization (ICAO), the International Air
Transport Association (IATA), the International Maritime Organization (IMO), the
US Department of Transportation (USDOT), Transport Canada (TC), and others.
Please contact the transporter and confirm current regulations before
transportation of lithium-ion batteries.
• Do not open, crush, or perforate batteries; doing so could cause injury.
• Do not incinerate batteries. Keep batteries away from fire and other sources of
extreme heat. Exposing batteries to extreme heat (over 80 °C) could result in an
explosion or personal injury.
• Do not drop, hit, or otherwise abuse a battery, as doing so could expose the cell
contents, which are corrosive and explosive.

The Olympus warranty only covers equipment that has been used in a proper
manner, as described in this instruction manual, and that has not been subjected to
excessive abuse, attempted unauthorized repair, or modification.
Inspect materials thoroughly on receipt for evidence of external or internal damage
that might have occurred during shipment. Immediately notify the carrier making the
delivery of any damage, because the carrier is normally liable for damage during
shipment. Retain packing materials, waybills, and other shipping documentation
needed in order to file a damage claim. After notifying the carrier, contact Olympus
for assistance with the damage claim and equipment replacement, if necessary.
This instruction manual explains the proper operation of your Olympus product. The
information contained herein is intended solely as a teaching aid, and shall not be
used in any particular application without independent testing and/or verification by
the operator or the supervisor. Such independent verification of procedures becomes
increasingly important as the criticality of the application increases. For this reason,
Olympus makes no warranty, expressed or implied, that the techniques, examples, or
procedures described herein are consistent with industry standards, nor that they
meet the requirements of any particular application.
Olympus reserves the right to modify any product without incurring the

Introduction
This user’s manual provides operating instruction for the 45MG ultrasonic thickness
gage. The information in this manual is organized to explain the technology, safety
details, hardware, and software. Practical measurement examples help the user
become familiar with the instrument’s capabilities.
This manual describes how to use the 45MG instrument’s advanced features,
including the use of special transducers, management of custom transducer setups,
software options, the datalogger, and communication with external devices.
The PDF file for this manual is included on the documentation CD
(P/N: 45MG-MAN-CD [U8147024]) that is shipped with the 45MG.

1. Instrument Description
This chapter describes the main features and hardware components of the 45MG
instrument.
1.1 Product Description
The 45MG by Olympus is a handheld ultrasonic thickness gage designed for a wide
variety of thickness-measurement applications. With the 45MG, you only need access
to one side of a part in order to obtain nondestructive measurements of the thickness
of corroded, pitted, scaled, granular, and other difficult materials.
The 45MG displays a thickness readout and offers an optional A-scan view for
waveform verification. The microprocessor of the 45MG continuously adjusts the
receiver setup so that every measurement is optimized for reliability, range,
sensitivity, and accuracy. An optional advanced internal datalogger can store up to
475000 thickness measurements and 20000 waveforms.
With the Single Element option, the 45MG operates with a full line of single element
transducers. Operation with dual element transducers is a standard feature.
Depending on the software options, the 45MG is capable of measuring material
thicknesses between 0.08 mm and 635.0 mm (0.003 in. and 25.0 in.). The temperature
range of measured materials may vary between
depending on the material characteristics, the transducer, and the measurement
mode.
−20 °C and 500 °C (−4°F and 932°F),
Basic features
• Measurement-related status flags and alarms
• Quarter VGA color transflective LED back-lite display

CAUTION
— Database enhancements include 32-character file naming and 20-character ID
naming
— Automatic ID number increments following a preset sequence, or manual ID
numbering using the keypad
— Save reading/waveform to an ID number
— Ability to simultaneously display ID number and stored reference thickness
while displaying active thickness and waveform
— Five file formats available
— Erase selected data or all stored data
— Standard USB directional communication
1.2 Environmental Ratings
The 45MG is a rugged and durable instrument that can be used in harsh
environments. The 45MG was designed to meet the requirement of the IP67 rating
(Ingress Protection rating).
Olympus cannot guarantee any level of ingress protection rating once the instrument
seals have been manipulated. You must use sound judgment, and take proper
precautions before exposing the instrument to harsh environments.
To maintain the original level of ingress protection, you are responsible for the proper
care of all routinely exposed membrane seals. Additionally, you are responsible for
returning the instrument to an authorized Olympus service center on an annual basis
to ensure that the instrument seals are properly maintained.
1.3 Instrument Hardware Components
The 45MG front panel features a color display and a keypad. The instrument comes
with a wrist strap. An optional protective rubber boot includes a dust flap seal for the
USB communication connector, strap rings at the four corners, and a stand at the back
of the instrument (see Figure 1-1 on page 20).
