Function: 1. All voltage divider resistors are 0.01% resistors to ensure temperature drift, and the output is buffered by the op-amp. 2. Factory calibration is calibrated by a FLUKE8846A with a 6 1/2 digit DMM and the measured voltage is marked on the shield housing. 3. Product accuracy and small size, easy to carry and store, with good practicality. 4. Product input voltage 15V, output voltage 10V / 7.5V / 5V / 2.5V etc. 5. Using high-quality materials, strong and durable, has a long service life.
