Introduction
EVOTIS is designed to detect defects and quantitatively measure damage of
composite structured materials. In order to fully realize its performance
capabilities, please read this operation manual carefully.
The follo ing general safety precautions must be observed during all phases
of operation of this instrument. Failure to comply ith these precautions or
ith specific arnings else here in this manual may impair the protections
provided by the equipment. Sysmic Co., Ltd. assumes no liability for the
customer’s failure to comply ith these requirements.
• Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases or
fumes. Operation of any electrical instrument in such an environment
constitutes a definite safety hazard.
• Keep A ay from Live Circuits
Operation personnel must not remove instrument covers. Component
replacement and internal adjustments must be made by qualified
maintenance personnel. Do not replace components ith the po er cable
connected. Under certain conditions, dangerous voltages may exist even
ith the po er cable removed. To avoid injuries, al ays disconnect the
po er and discharge circuits before touching them.
• Do Not Substitute Parts or Modify the Instrument
To avoid the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification of the
instrument. Return the instrument to the exporter for service and repair
to ensure that safety features are maintained.

Features
EVOTIS is designed to detect defects and quantitatively measure damage of
composite structured materials.
EVOTIS adopts the impact acoustic method using auto hammer, collecting
and analyzing sounds to detect defects such as disbonds and hollo s in
testing subjects.
Test results ill be notified to the operator in the follo ing manner:
1. When EVOTIS is in use, it displays both a standard value and a
measured value corrected from an auto hammer at each stroke. A
comparison of the standard and measured values are sho n in four levels
by three color LED lights and a buzzer sound at the designated ratio.
2. A half- ave length of the very first sound ave is collected from the
hammer as a measured value and is displayed as a three-digit numerical
value in units of 1 micro-second (Patent #3922459).
Measured values up to 7,700 strokes can be saved in the EVOTIS.
By connecting the EVOTIS ith a computer using a dedicated USB cable
hile the EVOTIS is in use, measured values can be transferred to the
computer in real time. Also, measured values saved in the EVOTIS can be
transferred to a computer after testing is completed. In order to transfer
measured values to a computer, the dedicated soft are included in the
package is required.

Using the EVOTIS
1. Connect Auto Hammer ith the main unit by connecting the hammer’s
connector cable to the Auto Hammer hub.
2. S itch on the po er button to turn on the unit.
3. Obtain a standard value by pressing the Standard Value button hile
placing the Auto Hammer’s head to the surface of the good portion of the
testing subject in the right angle. The hammer automatically hits the
surface of the testing subject four times. EVOTIS takes the average
measure of t o values, excluding the highest and lo est values, and uses
this as the standard value. This standard value is sho n on the unit’s
display. Once a standard value is obtained, the Ready lamp ill light up.
4. Press the Start/Stop button to start measuring the testing subject. Press
the Start/Stop button to stop operation. (Pressing the Start/Stop button
ith a longer stroke allo s continuous measuring of the testing subject.)
5. EVOTIS compares each measured value ith the standard value.
Differences are displayed by colored LED lights at the ratio belo :

Buzzer sound ill accompany red color LED lights.
Buzzer sound can be turned on and off by operator ith Buzzer
On/Off button at the console.
6. Recorded measured values can be seen by pressing the “+” and/or “―”
Memory button.

Safety Information
1. Follo the battery installation instructions carefully and make sure the
plus and minus poles face the right directions. Use AA Rechargeable
NiMH batteries (in the package). Replace ith ne batteries hen the
Battery lamp turns red.
Stored measured values are kept in memory hen the po er is turned off.
Ho ever, stored measured values ill be lost if the battery po er runs
out.
2. To avoid misreading test results, the standard value must be reset each
time a different material and/or difference in surface thickness is being
tested.
3. To avoid misreading test results, the surface of the testing subject must be
cleaned before operation.
4. Remove batteries if the EVOTIS is not in use for an extended period.
Care and Cleaning
Clean the surface of the case ith an alcohol-based substance. Do NOT use
any other solvents, including, but not limited to:
Alkali or alkaline salt solvents
Amines
Ketones (acetone methyl-ethl-ketone)
Aromatic hydrocarbons (benzene, toluene, exlene)
Esters
Halogen-based solvents (carbon tetrachloride trichlene, dioxane,
