Hartmann & Braun Multavi R VoltmeterThis Hartmann & Braun Multavi R Voltmeter is in good optical condition for its age. There are only some minor usage marks and some tape residue. Other than that no visible major damages. The H&B voltmeter is not tested and sold as is. Please take a good look at the pictures for the cosmetic condition of the Hartmann & Braun Multavi R Voltmeter.Overview:The Multavi R (R for constant internal resistance of 7500 ohms) is a special radio technology device first introduced in 1937. It is a pure voltmeter with 7 measuring ranges: 1.5 / 3/6/15/30/60 / 150V AC. By adaptation resistances the value of the internal resistance could be changed.Due to the constant input resistance, the output power could be calculated: Output power (watts) = (output voltage * output voltage) / matching resistorThe Multavi R was used to measure the output power of receivers and amplifiers, to adjust and measure the ripple voltages. Working condition: Not testedMissing or damage: See description for detailsPictures: See pictures for the cosmetic condition of this lotBuying terms: Sold as is! Show more
