Digital Multimeter B7-86/1 for Precise Voltage and Current Measurement

Multimeter B7-86/1 is designed to measure the basic electrical quantities: voltage and force of direct current, rms value of voltage and force of alternating current, resistance to direct current, frequency of alternating current, electrical capacitance, inductance. It provides measurement with non-normalised error of total, reactive and active power, power factor and p-n junction testing. B7-86/1 is powered by a rechargeable battery consisting of two accumulators. The battery is charged without removing it from the case. The multimeter software is written into the microcontroller memory at the production stage and cannot be changed during the multimeter operation. The software sets the internal configuration of the multimeter's components, ensuring that its operating mode corresponds to the mode set by the operator.
