1.1 HOW TO USE THIS MANUAL
Welcome to the Voltech ATi. Please study this introductory chapter of the
manual carefully. It will help you to set-up your tester quickly and safely.
The following symbol conventions are used throughout:
Important safety information. To ensure operator safety, all safety
information must be read and understood.
Important information that explains a general principle or refers to
other sections of the manual.
The contents of this manual are believed to be accurate at the time of printing.
Voltech reserves the right, however, to change the operation or specification of
the ATi without notice. No liability is accepted for the inappropriate, negligent,
or incorrect set-up of the ATi by the user, by either manual or automated
means.

1.2 GENERAL SAFETY INSTRUCTIONS
WARNING: The ATi must be connected to a safety
ground (earth). Only insert the power lead into a
socket with a protective ground contact.
Ensure that the power lead is in good condition and
free from damage before use.
Replace the fuse only with the same type and rating as indicated
on the rear of the ATi.
Refer servicing only to qualified personnel who understand the
danger of shock hazards.
WARNING: The ATi wound component tester can generate
voltages of up to 500V during insulation resistance testing.
Although the available energy of the source has been
limited in accordance with EN61010-1 and can be
considered ‘safe’, care should be taken to avoid accidental
or unexpected electrical shocks.
• Ensure operators are aware of the potential shock hazard.
• Ensure operators are trained to avoid making contact with
the part being tested or any exposed parts of the fixture
during an IR test.
• Construct safe fixtures using the guidelines given in the
fixturing section of this manual.
• Beware of testing parts with high turns ratios such that a
small applied test signal can generate an unsafe high
voltage.
• Beware of energy stored with the capacitance or inductance
of the part being tested when handling the part after test.

The ATi is very easy to use. However, it is a complex instrument, which can be
installed and operated in many ways.
In order to maximize the benefits that the ATi can bring to your test
environment, please study the following section carefully.
1.6 TYPICAL PRODUCTION INSTALLATION
Manual or robotic operation
• Barcode input
• Run-pad or footswitch to initiate operation
• Simple PASS/FAIL operation by an unskilled operator
Results
• Direct printing from the ATi printer port
• Results archiving to disk using the Server application
• Results for analysis can be easily exported to other Windows applications
Editor PC - used only when creating
or editing test programs. Server PC - for handling detailed results and large numbers of test
programs.
