中微子质量实验KATRIN要求主谱仪在-18.6 kV的延迟电位稳定性为3 ppm。为了监控稳定性，我们与德国国家计量机构Physikalisch-Technische Bundesanstalt（PTB）合作开发并制造了两台定制的超精密高压分压器。到目前为止，分压器的定期绝对校准需要将设备带到专业的计量实验室。在这里，我们提出了一种新的方法，该方法基于使用KATRIN装置测量两条$$^{83{\mathrm{m}$$83mKr转换电子线的能量差，该方法在2017年7月KATRIN的调试测量期间进行了演示。测量的高压分压器K35的比例因子$$M = 1972.449（10）$$M=1972.449（10）与4年前的PTB校准一致。该结果证明了校准方法的实用性以及分压器的长期稳定性。

The neutrino mass experiment KATRIN requires a stability of 3 ppm for the retarding potential at − 18.6 kV of the main spectrometer. To monitor the stability, two custom-made ultra-precise high-voltage dividers were developed and built in cooperation with the German national metrology institute Physikalisch-Technische Bundesanstalt (PTB). Until now, regular absolute calibration of the voltage dividers required bringing the equipment to the specialised metrology laboratory. Here we present a new method based on measuring the energy difference of two $$^{83{\mathrm{m}}}$$83mKr conversion electron lines with the KATRIN setup, which was demonstrated during KATRIN’s commissioning measurements in July 2017. The measured scale factor $$M=1972.449(10)$$M=1972.449(10) of the high-voltage divider K35 is in agreement with the last PTB calibration 4 years ago. This result demonstrates the utility of the calibration method, as well as the long-term stability of the voltage divider.
