How to get the AT1000 in the computer mode
Back to previous page


  1. class="Standard-Text">Important: FIrst do this, when you are outside the USA.
  2. class="Standard-Text">Install the Amplitrex 'tube test' program. Do not forget the settings of the .ini file, but that is all described in the AT1000 manual.
  3. class="Standard-Text">Start the tube test program, first without tester. The program should complain 'Unable to open Com port'. Click ok.
  4. class="Standard-Text">If the program starts now, it seems installed. Click the EXIT button. So the program stops.

Try all four COM ports, as some of those cables do not use port COM1 by default, but COM1, COM3 or COM4. If so, you can pre-configure this in the AT1000 ini file, so you don't have to do this every time you start up the tester.

So after you can apparently switch on and off the tube heater, the tester is ready to go, and you can continue with the rest:

Make a directory on your computer, where you will save the settings that we are creating here.
