5V Volt DC Precision Reference Voltage Standard 5.0000v

Description

This device can be used to check the calibration of your DVM or DMM.  The output is 5V and conservatively rated to be accurate within 0.001% (+/- 50uV) when new and within +/-100uV for a minimum of 6 months at room temperature between 65
º
F to 90
º
F. Initial value was nulled (+/- 10uV) to a calibrated Fluke 332B voltage standard and verified by a calibrated Agilent Keysight 34461A.
This Fluke 332b voltage standard was nulled to Fluke 5520A calibrator and verified by a Fluke 8508A (+6uV) in local ISO/IEC 17025:2017 accredited electronics calibration shop.
In order to reach the designed accuracy, thermal equilibrium of the internal electronics is required. Please turn the device on in a constant temperature environment at least 2 hours before taking any measurement.
The circuit is based on the LT12021-5 which uses buried Zener technology which has excellent long term stability.

chamber and
temperature coefficient
result shows equal or better than +/-1.5 ppm/ºC.
There is a power status LED. LED lit green indicates sufficient voltage for proper operation. If the input voltage is too low, the LED will turn red and cut off output voltage when unable to perform within specification.
This voltage standard is built using aluminum casing with better durability and better electromagnetic shielding for increased voltage output stability.
