10V/7.5V/5V/2.5V/1.24V AD585 Voltage Reference Module 0.1% 25PPM Used for Multimeter Calibration
Attention:
Before shipping, this product is calibrated using an original 6½-digit multimeter for HP, and the calibration data is included in a table—buy with confidence.
Description:
The AD585 reference module is powered via a Type-C USB 5V input, with a working current of around 15mA, so any USB port can be used for power.
All voltage outputs (10V, 7.5V, 5V, 2.5V and 1.24V) are not exact integers, but very close to the nominal values. Because the module is calibrated using a high-precision multimeter, you can use it to compare and verify the accuracy and linearity of your own multimeter.
This module provides both voltage and resistance references:
* Voltage (5 levels): 10.000V, 7.500V, 5.000V, 2.500V and 1.24V – selected via DIP switch.
* Resistance (5 levels): 10Ω, 100Ω, 1KΩ, 10KΩ and 100KΩ – built with 0.1% precision, 25PPM low-drift copper-lead resistors.
Application:
* Ideal for checking the accuracy and linearity of 3½-digit or 4½-digit handheld multimeters.
Features:
* Five Voltage Levels: 1.24V, 2.5V, 5.0V, 7.5V and 10V
* Powered via 5V Type-C port. Compatible with phone chargers, laptop USB ports, and power banks — convenient and flexible power source options
* Voltage selection via DIP switch. It is easy to operate
* Factory-calibrated using an HP3457A 6½-digit multimeter
Packing List:
* 1 × Voltage Reference Module
