CL5
g
Ultrasonic Precision Thickness Gauge
Micrometer Precision in a Rugged Package
The CL5 is an easy-to-use precision thickness measuring
solution for components used in the automotive and
aerospace industries, such as:
• Cast and stamped metal components made of
aluminum, steel, copper, bronze
• Machined workpieces
• Chemically milled components
• Metal strips, metal plates
• Plastics and composites
• Glass
The instrument can be held in one hand or placed on
flat workpieces, making the CL5 a compact way to test
your material for the required thickness or checking for
sheet corrosion.

Compact Solution With a Full Range of Functionality
The CL5 precision thickness gauge offers a full range of
functionality in an easy to use, compact and rugged package.
Three soft keys directly under the display activate the functions
shown on the display menus. Four directional keys help make
menu changes and navigation of the text entry screen simple
and efficient .
The graphical display presents the user with seven different
operation modes. The user can select Normal, Minimum Scan,
Maximum Scan, Differential/Rate of Reduction, Thk+A-Scan
(option), Velocity (option) or Quality View. The CL5 uses a
programmable data recorder for easy set up of data files from
the PC. The SD Card memory system places all the data
recording and set-up information on a removable SD memory
card. The files are formatted allowing drag and drop files when
plugged directly into the PC. Other data such as digital
photographs can also be stored on the same SD card. The CL5
allows direct connection to the PC, using a serial or USB port
(with optional cable).
Simple Operation
The CL5 is a very straightforward instrument to operate. The
MODE key progresses the user through a series of selection and
set-up menus and back to the measurement mode. One press of
the MODE key displays a table of standard probes and up to five
special set-ups. Another press of the MODE key displays a set-up
menu where the user can easily scroll through the menu, see the
current settings and make fast changes to any of the displayed
settings.
A supervisor lock-out function enables a knowledgeable user to
set up all the specific measuring functions and settings of the
CL5 and lock the settings so critical settings cannot be changed
by a subordinate user.
Additional advantages offered by this compact, multifunctional
instrument include:
• Enhanced measurement performance produces stable and
repeatable thickness values
• Seven measurement and display modes: Normal, Minimum
Capture, Maximum Capture, Differential and Rate of Reduction,
Velocity (with CL5 VL option), Thickness+A-Scan (with Live A-Scan
Option) and Quality View Mode (with Data Recorder option).
• Snapshot A-Scan on all models
• Hollow/Fill thickness digits showing coupling or non-coupling
status
• Visual LED alarm to alert user when measurements are
exceeding the user selectable limit values
• Customer parameter set-ups for special configurations and
quick instrument set-up
• Flexible power system via standard AA batteries or
rechargeable battery pack system (standard)
• Multi-language user interface
• Automatic ultrasonic performance (gain and gate controls)
• Wide variety of standard probes (sold separately)

The Velocity Option: Performance and Flexibility
The CL5 Velocity option gives the user an added measurement
mode used for determining the velocity of a known thickness of
material. Material thickness can be entered manually via the CL5
keyboard or a digital caliper can be connected, allowing the
thickness value to be sent electronically from the caliper to the
CL5. The user simply places the probe on the part, and the CL5
displays the material velocity of the test object. Both the thickness
and the velocity value can be stored in the Data Recorder and
downloaded to the PC.
The Live A-Scan Option
The optional Live A-Scan feature gives the user a real time view of
the echoes being digitally measured by the CL5.
Viewing the Live A-Scan can aid users when attempting to
properly align the probe and the test object to achieve the best
measurement values. Viewing the Live A-Scan enables the user to
ensure the proper echoes are being measured and the digital
value is correct.
The Data Recorder Option
The Data Recorder option permits the quick and easy storage of
thickness values in file form. Fully user-programmable, it stores up
to 10,000 measured values or as many as 500 values with
attached A-Scan.
The programmable data recorder allows creation of data recorder
files directly from the CL5 keypad, or from the PC using the
flexible UltraMATE
®
or UltraMATE®Lite software program. The
Data Recorder supports the use of alphanumeric file names,
standard linear and grid files and custom linear files.
Extended file types store the thickness values, velocity settings
and other critical data for each measurement point, making the
CL5 and UltraMATE
®
ideal for test data management.

Achieve More Precision With
Quality View
Quality View Mode permits Data Recorder-driven control and
capture of thickness measurements. It is ideal for singular parts
or structures with numerous measurement points that have
different target thicknesses and/or varying upper and lower limits
or tolerances.
Uses of Quality View Mode include:
1. Fast collection of thickness measurement data for statistical
analysis during variation control and quality assurance.
2. Digitally capturing thickness measurement data for quality
records and traceability.
3. Variation control of work in progress on the manufacturing or
workshop floor.
Quality View Mode displays the current measurement location
name, a bar graphic of the thickness measurement that shows
the lower specified limit value, the nominal/target value, the
upper specified limit and a numerical readout of the
measurement.
Selection of Quality View Mode displays
To work in Quality View Mode, custom four-point linear files are created in either Microsoft®Excel or UltraMate®software applications
on a PC and downloaded to the CL5 using the optional serial or USB cable. Measurements can also be uploaded into a PC for
processing and analysis using Microsoft
®
Excel, UltraMate®or a third party statistics and/or quality software application.
