A means of measuring the high voltage output is essential. A resistive divider is appropriate for this application. However, standard components are not suitable for high voltages, low current measurements. A good circuit for measuring the output voltage is a potted TV focus divider (RCA SK series or equivalent) which contains the necessary high voltage/high value resistors. The only additional components needed are one external resistor and a standard high impedance dc meter.

The dekatron fell out of practical use when transistor -based counters became reliable and affordable. Today, dekatrons are used by electronic hobbyists in simple "spinners" that run off the mains frequency (50 Hz or 60 Hz) or as a numeric indicator for homemade clocks.
