The Type 1822 is designed to produce accurate voltages for the testing and calibration of digital voltmeters. | The Type 1822 is designed to produce accurate voltages for the testing and calibration of digital voltmeters. | ||
as a precise voltage reference from 100 μV | It can be used as a precise laboratory voltage reference from 100 μV DC to 1111.1 V DC. | ||
The output voltage is displayed using a mechanical digital display with automatic units and decimal placement. It can set to any value with five-digit resolution, the resolution is adjustable. | |||
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. | |||
