Description
Отличительной особенностью пред, лагаемого способа вл етс то, что изменение характера градуировки шкалы осуществл ют путем создани сеточного тока в цепи усилительной лампы, вызьтающего изменение характеристики последней.A distinctive feature of the previous method is that the change in the nature of the graduation scale is carried out by creating a grid current in the circuit of the amplifying lamp, which changes the characteristic of the latter.
Сущность изобретени состоит в особом включении первой лампы катодного вольтметр а, при которОМ в цепи сетки усилительной лампы с увеличением измер емого напр жени возникает сеточный ток, измен ющийс в начальной части по закону, близкому к экспоненте.The invention consists in specifically switching on the first cathode voltmeter lamp a, at which in the grid circuit of the amplifying lamp a grid current arises with an increase in the measured voltage, varying in the initial part according to a law close to the exponent.
Схема Катодного вольтметра и включени первой лампы показана на чертеже.A diagram of the Cathode Voltmeter and the switching on of the first lamp is shown in the drawing.
Анод лампы i типа «жолудь присоединен к клемме «земл . С ростом измер емого напр жени отрицательный потенциал на сеткеThe anode of the lamp i of the type “acorn is connected to the terminal“ ground. With increasing measured voltage, negative potential on the grid
лампы Лч уменьшаетс . При дальнейшем росте измер емого напр жени результирующее напр л ение на сетке Лг изменит знак и по витс сеточный ток. При по влении сеточ. ного тока уменьшитс ч вствительность схемы, чем и достигаетс необходимое изменение градуировки шкалы показаний прибора.lch lamp is reduced. With a further increase in the measured voltage, the resulting voltage on the grid Lg will change sign and the grid current will appear. With the appearance of the mesh. The current of the circuit will decrease, so the necessary change in the calibration of the instrument scale is achieved.
Предмет изобретени Subject invention
Способ изменени градуировки шкалы и приближени ее к логарифмической в приборах типа катодного вольтметра с диодным детектированием , отличающийс тем, что изменение характера градуировки шкалы осуществл ют путем создани сеточного тска е цепи усилительной лампы, вызывающего изменение характеристики последней.The method of changing the graduation scale and bringing it closer to the logarithmic in devices such as a cathode voltmeter with diode detection, characterized in that the change in the nature of the graduation scale is carried out by creating a grid circuit of the amplifying lamp, causing the latter to change its characteristics.
