B7-57/1 voltmeters

Application of the most advanced methods of measurements and use of modern achievements of technology provides to the device high operational characteristics and magnificent quality of measurements. Distinguishes this model: high speed, small errors and high stability of measurements. Thanks to existence of the built-in IEEE-488 interface perhaps remote control of process of measurement from the personal computer or a conclusion of results of measurements to the winchester, the plotter, the printer. The LCD display with two information fields providing not only indication of size of the measured parameter, but also simultaneous indication of tension of the device integrator operating at present at the exit, creates special conveniences during the work with the device in the modes of measurement of resistance and current. Existence of an analog output allows to connect the graphic recorder to devices.
