Simulated Tube Test. If you are unsure about how to calibrate the tube tester don't do it. High Voltage There is the possibility in a tube tester that the phase of the heater windings could be reversed. If this was the case the meter would deflect backwards, if that happens then 2 and 7s base connections would need to be swapped. This is built from: A semiconductor based “ACS” – the Alternating Current Sink – 1000uMho calibration tool. Dr. H. Holden, Jan. 2017. When you calibrate after the military manual you need the Simulated Tube Test. It's an easy tool to use instead to use a variac isolations transformer etc, you can use this tool to calibrate your tube tester. You messaure two values (“CalB” + CALC 9V) 1000uMho see picture. It is important that the grid signal is correct around 5v ac and the bias signal for correct calibration.
