The total operating time was 18 hours, 22 minutes on 10 separate occasions.
Most portable light sources are relatively low in light intensity and have short operating times.
The operating time is not a fixed interval, but decreases as the current increases.
A control on the front panel adjusts the operating time between limits of less than one second and four minutes approximately.
For a longer operating time it could be increased in value.
Some may be manned during fewer hours than the operating time each week.
The surgical simulation is a key factor in reducing the actual operating time.
Most of these industries are very capital intensive and the management is therefore very concerned about lost operating time.
The camp operated from 10 October 1945 until middle of March 1948 (total operating time was 29 months or 880 days).
The Ratio is the percentage increase in effective operating time caused by the change-over.
