13 Performance Test (with Service Software)
13.1 Starting the Program
•
Booting in DOS:
All service programs of CTS are only accessible under DOS. Since only part of the VGA picture is
displayed on the internal LCD, an external VGA-compatible monitor has to be connected to the rear
SERVICE connector before booting. An external keyboard must be connected to the CTS to enter
the DOS level. After switching on the CTS, a short tone and then three short tones are heard. The
keys <Alt>, <Control> and <E> must now be pressed within 1.5 seconds. Make sure not to press the
key <E> before the two other keys have been pressed.
Once the controller startup is completed, the DOS prompt is displayed on the external monitor.
If switchover fails, switch off the CTS and repeat the procedure.
Note:
Files must not be modified or deleted. This would impair compliance with specifications and proper
functioning of the CTS.
SW_CRT or SW_LCD switches between external monitor and LC display.
•
Change directory: cd \service <ENTER>.
•
Call performance test program: check <ENTER>.
13.2 Operating the Program
The program can only be operated with the aid of an external PC keyboard. The key of the external
keyboard is represented similar to a softkey and given in brackets "<>". The default key has a double
margin; it can be selected with any unused key, eg <SPACE> or <ENTER>. The running test or the
program can be aborted with the <ESC> key of the external keyboard.
Following the start messages the CTS status is displayed. Check whether the instrument model and all
options fitted have been correctly identified.
After confirmation, the test selection menu is displayed. For selecting a menu item, position the cursor
next to the desired menu item using the <Cursor up>, <Cursor down>, <Page up> and <Page down>
keys, and press the <ENTER> key.
When a test point is entered it is assumed that no external measuring instrument is connected.
After a test has been selected, the user is prompted step by step through the various actions, such as:
Connecting external measuring instruments to the CTS, settings and measurements on the test
equipment as well as reading CTS-internal measurement results.
When the requested action is completed, the test run is continued by pressing the default key. With a
number of measurements the current or the preceding measurement can be repeated or the
subsequent measurement skipped.
Some instructions are output together with additional information to simplify troubleshooting.
The program is left by switching off the instrument.
