Operation Manual
1.7 Cooling Time
The equipment has incorporated a variable-cooling time function. X-ray radiographic may
be repeated consecutively three or four times after it has not been used for a long time;
however, the X-ray tube head, once reaching a given temperature, should be cooled for a
given time depending on the radiographic conditions as shown in the following table.
The cooling time of the equipment are as described in the following table.
