Radiographic exposures can also be initiated with the X-ray Handswitch which
is connected to the Control Console.
The X-ray Handswitch button has three positions: "Off", "Preparation", and
"X-ray Exposure", which operate in the same way that "Prep" and "Exp"
push-buttons on the Control Console.
Press the Handswitch half-way for "Prep" and fully for "Exp".
This X-ray Generator is equipped with a Heat Unit Calculator. During
exposures, the Heat Units are calculated and totalled.
To view the remaining Heat Units, press the "On" push-button. The kVp Display
shows the percentage of Heat Units that remain preceded by the letter "H". For
example, a display of "H75" would indicate that 75% of Heat Units capacity of
the X-ray Tube remains. "H -- -- " indicates that all the capacity remains. The kVp
Display reverts to its normal function after releasing the "On" push-button.
The operator can read the number of exposures made by the Generator, as
indicated below:

The number of exposures is shown on the kVp and mAs Displays, up to a
maximum of 999,999 exposures.
