Description:
Returns the total amount of time that high voltage has been off since
the tube was last seasoned. This off time includes time when the
power supply was turned off and the time where the supply is on but x-
rays (and thus high voltage) were off (that is, the supply is in idle).
Syntax:
<STX>HVOF;<CSUM><CR><LF>
Response:
<STX><ARG1>,<ARG2>;<CSUM><CR><LF>
Where:
ARG1 equals the hours and ARG2 equals the remaining hundredths of
hours that the high voltage has been off.
Example:
<STX>163,27;<CSUM><CR><LF> means that high voltage has been
off for 163.27 hours
