Description

ZM1176 is a cold-cathode Nixie indicator listed in the supplied German comparison catalog as comparable to RFT type Z573M. The referenced RFT table publishes a striking value of 150 V, a maintaining/glow value of 140 V, an extinction value of 120 V, along with cathode-current, display, environmental, and mechanical data. The catalog explicitly cautions that comparable tubes are not necessarily identical, so these mapped RFT values are retained as comparison data rather than asserted as exact original-manufacturer ratings.
