• The features and functionality of the AT3600 tester.
• Internal functionality.
• How the tester executes each test.
• What appears in a test program.
• How programs are created, archived and then used in actual test.
• Test fixtures.
• Typical manual and robotic test situations.
• Safety systems.

Because the programming of each test is done at a high level, it is not strictly necessary for you to know the details of how tests are executed within the tester.
However, for some users this subject may be of interest, therefore a brief explanation has been included here.
When the test program is loaded into the tester, each individual test is assembled into a sequence of operations involving the components in the functional block diagram shown previously. The sequence is different for each test, and in some cases, it depends on which are the preceding and following tests in the program; but in all cases, it is optimized to give the best measurement speed and accuracy.
The Test Program Editor supplied with your tester allows you to create such a program simply and easily without any need for software programming skills. Each test required for the program is selected from a list of ‘available tests’ by clicking with the mouse. The test details (such as the transformer terminals, test conditions, and pass / fail limits) are then entered into a form fill dialogue box.

The Editor software previously described, allows you to create and evaluate each individual test program. It is not intended to manage the large numbers of test programs that may be required on a daily basis once they are in ‘production’ use.
This is the function of a second PC program supplied with your AT3600.
Usually, the Server would be installed on a PC with access to a large disk, which could be attached to the PC itself, or connected via a network. The Server (and disk) could then be optionally used for either or both of two purposes:
• To provide the master archive for test programs
• To archive test results
The tester has a separate ‘Server’ port on its rear panel for connecting to the Server.

Advantages
• Convenient storage and management of large numbers of test programs (e.g. >1000).
• Easy storage and management of test results.
• Importing results into other Windows applications for analysis.
• The Server PC could be located away from the test area, for example in a supervisor’s office, allowing results analysis to be performed where it is required.
• Up to 8 AT Series testers may be connected to each Server PC Limitations
• Requires the Server PC to be permanently connected. This is to allow the tester uninterrupted access to the server, for the purposes of accessing programs and storing results.
• Usually requires an additional PC (which could be a portable) to be attached locally to (the Auxiliary Port of) one of the testers when a new program needs to be developed and evaluated.
Small Production Facility
At the other extreme, possibly more suitable for a small production facility with a single AT Series tester and limited or temporary access to a PC:
• Connect the AT to the PC (running both Editor and Server software) as shown above when developing the test programs.
• Download a group of programs from the Server to the AT, where they will be held in the internal non-volatile memory.
• Remove the PC, and run all the production test programs from the AT internal memory.
