Application Notes
The tube may be started and satisfactory operation will result between 0 and 90°C. For maximum life the condensed mercury temperature after warm-up should run between 40 and 90°C (OCR error 440-490) which corresponds to approximately +15 to +65°C ambient. Light filament before applying load.
