The DVR-150 and the DVR-300 are precision resistor/capacitor high voltage dividers that provide low voltage outputs proportional to the applied high voltage input. Their 1000:1 amp; 10,000:1 ratios, respectively, extend the measurement capability of most digital voltmeters and oscilloscopes to 150,000 volts or 300,000 volts.
The divider includes a switchable low-end impedance to match various metering inputs. Both are suited for wave-shape/harmonic analysis using a standard oscilloscope and can be used to measure DC multiplier circuits or AC transformers, limited only by the Digital Volt Meter (DVM) connected as the metering device. They are not designed for impulse or square wave applications.
