B7-82

Voltmeter V7-82 is a high-class professional device, which allows to measure DC and AC power and alternating current, DC resistance, frequency and period of electrical signals.

It can be operated in harsh environments while with the same performance characteristics.

Range Overview

The presence of the LED allows the device to operate in low light conditions.

The presence of CPC interfaces (IEEE-488) and the joint C2 (RS-232) allows you to use the device in the information-measuring systems.

Built-in microcontroller performs mathematical processing of measurement results and provides the following service functions:

  • as an external calibration;
  • temperature measurement;
  • ratio measurement of in dB;
  • power measurement;
  • filtering program;
  • determination of extreme values of the measured value;
  • tolerance control of measured parameters for compliance with the thresholds;
  • testing g of the circuit connection and diodes testing;
  • "Memory"program  (a set of N measurements of the array via a programmable time interval);
  • displacement of the measurement result by a constant, multiplication and division by a constant, percentage deviation from a constant.
