Calibration re-verified on 01/06/2024 & on 6/03/2024.Our TV7D/U reads Transconductance(Gm) on a scale of 0-120 (push button #3, for rectifiers button #7). This TV7D/U will read mA plate current emissions directly by depressing Gm button and the red button on the digital meter, We use the last publishedxls spreadsheet by Nolan Lee to transpose actual TV7 digital meter readings 0-120into actual Transconductance(Gm) #'s in uMhos based upon the selector switch setting A-F.All versions of TV7's and most Hickok designed tube testers will test tubes at a maximum of 150V Plate Volts and Grid #2 at 130V volts and Control Grid #1 (Bias control) at ranges from 0 to -30Volts.
