Typically, the boost time should be between 200 and 250 msec, and the preheat time should be in the range of 700 - 800 ms.
If in doubt, monitor the filament feedback and be sure that there is no change in the signal level 5 ms. after the start of an exposure, and that
the mA starts at the selected level.
Standby current must be below the emission point.
If the maximum filament current is increased, be careful not to exceed the tube manufacturer's specifications.
Use and disclosure is subject to the restrictions on the title page of this CPI document.
