【 摘 要 】

In this work meter for the phase difference of the variable components of the discharge current and the voltage drop was developed and tested. The operation of the meter is based on the transformation of harmonic signals into rectangular pulses, and further determination of the time shift between them. The possibility of using this meter for monitoring the dynamic resistance of glow discharge lasers is shown.
