OPERATING INSTRUCTIONS QCP385 issue 2 Job site safety precautions Instruments The radiographer and his assistant must at all times wear a film badge or TLD and pocket dosimeter with a range of 0-200mRem (0-2mSv). Regulatory requirements in the USA also require that an audible alarm ratemeter be worn at temporary jobsites. Specifically, those locations that are not permanent radiographic installations equipped with functional door interlocks and audible/visual alarms. Radiographers in the USA mus

OPERATING INSTRUCTIONS STEP 2 WARNING Ensure that the available length of the control cable is greater than the total length of the source guide tubes. See the technical specifications section for details. If the remote control conduits are shorter than the total length of the source guide tubes: 1 The source assembly cannot be projected all the way to the source stop of the terminating source guide tube and be correctly positioned for the exposure. 2 The source assembly may not reach a collimat

OPERATING INSTRUCTIONS STEP 4 Projecting Rapidly rotate the control crank handle in the EXPOSE direction (counter-clockwise) to move the source assembly out of the exposure device to the radiographic focal position. The control crank handle will stop turning when the source reaches the source stop. Do not use excessive force. The odometer (if fitted) will indicate the approximate total distance traveled, 7ft (2.1m) for each guide tube section. Set the brake to ON to prevent movement of the sourc

OPERATING INSTRUCTIONS STEP 4 Retracting At the end of the required exposure time, set the brake to OFF and rapidly turn the crank handle in the RETRACT (clockwise) direction until it no longer moves. You may hear the lock slide ‘click’ back into its original position depending on the ambient noise level at the job site. From the control crank you may be able to observe the GREEN MARKING on the slide bar. Apply a slight amount of forward pressure on the crank handle as if to expose the source to
