Description
Based on the excellent LT1021 IC, the 389-1 low cost voltage reference is designed to provide an accurate and repeatable precision 10V DC for general use around lab and workshop. The 389-1 is built into a robust metal enclosure, with the sensitive electronics sealed in silicone to reduce changes due to humidity. With a temperature coefficient typically less than 2.5ppm/oC and aged for 200+ hours before final adjustment.
Features & Specifications
- Output: 10V +/-0.003% (30ppm)
- Internal (2x 9v batteries) or External DC powered (12-15V@ 30mA)
Calibration
All voltage references are adjusted/calibrated in-house and given a final calibration prior to being dispatched. Final calibration is checked against our Keysight 34465A (calibrated by a UKAS approved laboratory). We issue a Certificate of Calibration with each reference.
