}} | |||
The {{Title|General Radio 1822 Digital Voltmeter Calibrator}} was available in {{Catalog U}} only. | |||
The Type 1822 is designed to produce accurate voltages for the testing and calibration of digital voltmeters. It can be used | |||
as a precise voltage reference from 100 μV dc to 1111.1 V dc for laboratory use. The output voltage can set to any value with five digit resolution, the resolution is adjustable. The output voltage is displayed using a mechanical digital display with automatic units and decimal placement. External programming is available through a rear panel connector along with an internal automatic step function. Other features include an interference voltage function, polarity reversal, and adjustable output impedance. | |||

* '''Output Voltage:''' 100 μV dc to 1111.1 V dc in 7 decade ranges | |||
* '''Output Impedance:''' <0.5 Ω on 1 V through 1 kV ranges; 200 Ω on 1 mV through 100 mV ranges; A l kΩ, 10 kΩ, or 100 kΩ output resistor can be added to above impedances by front-panel selector switch | |||
* '''Output Current: 10 mA at full range on 1, 10, and 100-V ranges; 1 mA on 1 kV range | |||
* '''Accuracy:''' ±(30 ppm of voltage + 10 ppm of full range + 3 μV) on all ranges except ±(50 ppm of voltage + 10 ppm of full range) on 1-kV range; Accuracy of rear-panel voltages ≤111 mV, ±(30 ppm of voltage + 10 ppm of range +0.5 μV) | |||
