Keysight (formerly Agilent T&M) 427A AC Analog Voltmeter
Manufacturer Keysight (formerly Agilent T&M)Description
Description
The HP 427A Voltmeter is really a multimeter with the ability to measure AC, DC+, DC- Volts and Ohms. It has a mirrored analog meter. The black common 5-way binding post is isolated from the instrument chassis. The AC measurements are average responding not true RMS. Specifications: AC Voltage Range 10 mV – 300 V DC Voltage Range 100 mV – 1000 V Frequency Range 10 Hz – 1 MHz Interface 10 Mohm. Before the handheld DMM this was the general purpose lab instrument used for common electrical measurements. It can be powered from an AC line using the standard IEC power cord (110 or 220) or from an internal 22.5 Volt Battery. There is a carrying handle on the top so it can be used in the field like the DMM is used now. Maybe it could be called an AMM “Analog Multi Meter”.
