KVp fit testing can be done by using a cassette Wisconsin, penetrometer, digital kilovolt meter, and digital multimeter test tool. According to Minister of Health of the Republic of Indonesia No. 1250 / Menkes / SK / XII / 2009, the method for testing the output voltage plane X-ray tube can use the digital kilovoltage peak (kVp) meter. In general, digital kVp meter is more commonly used because after eksposi size kVp displayed automatically. In this test using a digital multimeter test tool for more accurate results. The purpose of this test is to determine the amount of output kVp is set on the control panel in accordance with the kVp air out of the X-ray tube (Papp, 2011). According PERMENKES No. 54 In 2015, that testing or calibration of medical devices is done on a regular basis at least once a year. According to Papp (2011) and Lloyd (2001) checking or testing equipment radiology performed every year once the plane X-ray equipment, and the equipment that had just repaired. Tolerance limit deviation between the set with a kVp X-ray beam produced is ≤ 5% (Papp, 2006).
