1 00:02:30,000 --> 00:02:34,220 It just reduces the pressure depending upon the householder. 2 00:02:34,220 --> 00:02:37,540 This is where you don't mess with its functions. 3 00:02:37,540 --> 00:02:41,360 You only mess with the circuitry in which the test's going to happen. 4 00:02:41,360 --> 00:02:46,420 Anyway, it's going to slow, levitate, usually using two cathodes, 5 00:02:46,420 --> 00:02:49,360 and constantly increasing its voltage. 6 00:02:49,360 --> 00:02:52,600 It's a translation of this. 7 00:02:52,600 --> 00:02:53,760 Thanks.
