by Raytheon. Rectifier tubes should read in the green sector if satisfactory. Separate tests are made for each plate. In the center of the panel are two push buttons marked “GAS TEST” and “AMPL.TEST". The button “AMPL.TEST” is used when testing all tubes having mutual conductance, that is, all amplifier tubes.

That is not Dynamic Mutual Conductance. In the 510X and 530 tube testers there is applied to the grid, in addition to its regular direct current “C” bias, an alternating signal voltage which modulates the plate current.

The following simple illustrations will make clear the value of the mutual conductance test, and the fallacy of the emission test. The above figure represents a conventional stage of resistance coupling. The gain for this stage is the product of the resistance, R, multiplied by the Mutual Conductance in mhos of the tube T1.

In the 510X and 530 testers, the pin jack to the LEFT is to be connected to ANT. post of radio receiver.

scale reading is 30 ohms. In this position, resistance as low as 1/10 ohm can be estimated. The third range on the ohmmeter multiplies the scale by 100 . In this range, the center reading of the scale is 30,000 ohms. The connecting leads are placed in the corresponding pin jacks.

17.6 Henries. In like manner, when measuring chokes of any size divide the reading in microfarads into 7.04, which will give the result in Henries. If it is desired to measure the inductance of a choke coil with a D.C. component of current, connect a small dry battery in series with one of the connecting leads.
