Изобретение относитс  к электроизмерительной технике и может быть использовано в промышленных и лабораторных измерени х электрических характеристик материалов и объектов.The invention relates to electrical measuring equipment and can be used in industrial and laboratory measurements of the electrical characteristics of materials and objects.

Известны устройства дл  контрол  электрических характеристик .материалов, содержащие токовые электроды, к которым через разделительные сопротивлени  подключены источник питани  и крайние выводы переменного резистора, а также два измерительных электрода, подключенных к выводам индикаторного тока, другой вывод одного из которых подключен к среднему выводу переменного резистора непосредственно, а другой вывод второго - через схему компенсации 1.There are known devices for monitoring electrical characteristics of materials containing current electrodes to which a power supply and extreme terminals of the variable resistor are connected through separation resistances, as well as two measuring electrodes connected to the indicator current terminals, the other terminal of one of which is connected to the middle terminal of the variable resistor directly, and the other output of the second - through the compensation scheme 1.

В таких устройствах сужены функциональные возможности ограничением числа контролируемых сигналов, необходимостью использовани  схем компенсации с соответствующим элементным усложнением и снижением стабильности измерений от питани .In such devices, functionality is reduced by limiting the number of monitored signals, the need to use compensation circuits with the corresponding elemental complexity, and a decrease in the stability of measurements from the power supply.

Целью изобретени   вл етс  расширение функциональных возможностей путем увеличени  числа контролируемых сигналов приThe aim of the invention is to extend the functionality by increasing the number of monitored signals during

обеспечении идентичности и повышенной стабильности измерений.ensuring identity and increased stability of measurements.

Это достигаетс  тем, что в устройство дл  контрол  распределени  потенциалов в образцах материалов, содержащее токовые электроды, к которым через разделительные резисторы подключены источник питани  и крайние выводы переменного резистора, средний вывод которого через одну из измерительных цепей, состо щей из индикатора тока и измерительного электрода, соединен с образцом материала, дополнительно введены переменные резисторы и индикаторы тока, причем число первых соответствует числу остальных измерительных цепей, а число вторых вдвое меньще числа всех измерительных цепей, введенные переменные резисторы соединены с образцом материала так же, как и первый переменный резистор, а средние выводы всех переменных резисторов соединены попарно через дополнительно введенные индикаторы тока.This is achieved in that a device for controlling the distribution of potentials in samples of materials contains current electrodes to which a power supply and extreme terminals of a variable resistor are connected via separation resistors, the average output of which is through one of the measuring circuits consisting of a current indicator and a measuring electrode , connected to the material sample, variable resistors and current indicators are additionally introduced, the number of the first corresponding to the number of the remaining measuring circuits, and the number of the second in howling mensche number of all the measuring circuits, input variable resistors are connected to the sample material as well as the first variable resistor, and the average of all the conclusions of variable resistors are connected in pairs via further input current indicators.

На чертеже дан один из вариантов схемы предлагаемого устройства.The drawing shows one of the variants of the scheme of the proposed device.
