B7-53

B7-53 is a high-quality digital versatile instrument, that using the latest microprocessor technology, has a much larger set of functionality than similar devices in the same price range.

This device not only measures voltage, current, resistance, electrical tests and performs diode tests, but can also measure frequency, period, temperature and power.

Used by 5 1/2 digit LCD display provides measurements with a resolution far exceeding the capabilities of conventional instrumentation.

Range Overview

Depending on the required accuracy and speed of measurements the instrument can operate in a zone 4 1/2 or 5 1/2 digits.

Built-in IEEE-488 allows you to successfully use the device as part of automated information-measuring systems.

Additional software features:

  • calibration, measurement of temperature by measuring the thermometer resistance;
  • the relative levels measurement in decibels;
  • power measurement;
  • voltmeter test control;
  • current measurement with an external shunt;
  • determination of the mean value of the specified number of measurements;
  • determination of extreme values of measured quantities;
  • tolerance control;
  • creating an array of measured values.
