3.3.10 Verifying Your Program
Typically in production use, your program would be downloaded to AT Series Tester from the Server, which is a PC resident software package, described in detail in Chapter 4. However, before you transfer your program to the Server archive, you should always verify it by running it on an actual transformer.
The Editor software will enable you to download a program directly to the tester, and to execute it from the PC keyboard.
Before you attempt to run the program:
1. Make sure you have connected your tester's Auxiliary Port (on the rear panel) to a suitable Comm Port on your PC. (This may be Comm Port 2 if your mouse is already using Comm Port 1.)
2. Set up the Comm Port on the PC.
From the Top Level menu, select
In the dialogue box, select the PC communications port which is connected to the tester.
WARNING: If the chosen ‘COM’ port is reserved by another Windows application, an error message will appear. You should select another port.
3. Fit the appropriate fixture to the tester and plug in the specimen transformer.
You are now ready to download and run your test program.
4. From the Top Level menu bar, select:
The Editor will now down-load the test program to the tester. After a few seconds, you should see a message to say that the Download was successful.
5. Again, from the Top Level menu bar, select:
The test program will now begin execution.
When it is finished, you will see a dialogue box containing the results of the test.
From the results, you should be able to see any tests where there may be problems. Return to the Program Editor to make the necessary changes, then download the program again, and run the corrected version.
Continue in this way until you are satisfied that the program is correct, before archiving it for use in production.
The code at the end of each result line should normally be zero; any other code signifies that an error occurred in the measurement.
At this point, you may want to protect your test program by setting an AT password. To do this, select:
Tester > Set Password
The resulting dialogue (see below) allows the AT password to be set. If a password is set, this password will need to be entered into the AT whenever a test program is changed or deleted.
Note that this Editor dialogue also allows the password to be reset. The old password is not required to do this. All that is required is for the new password to be entered and verified.
