Video Transcription
| 00:11.010,0:00:19.609 | The RaySafe 452 comes with two lids: the Air kerma lid is gray and the Ambient lid is yellow. |
| 00:19.609,0:00:21.570 | Just a note before we start. |
| 00:21.570,0:00:27.400 | The limited models, called RaySafe 452 Ambient and RaySafe 452 Air kerma can only measure with the lid mounted. |
| 00:32.140,0:00:34.000 | We start with the air kerma lid. |
| 00:34.000,0:00:39.469 | I you want to change the air kerma unit, you press the up button three times. |
| 00:39.469,0:00:42.940 | I want to measure in Gray (Gy). |
| 00:44.460,0:00:48.740 | Press the center button to return to the measurement screen. |
| 00:49.380,0:00:52.960 | To measure counts, you take the lid off. |
| 00:53.140,0:01:00.220 | The quantity automatically changes to counts, without any manual settings. |
| 01:01.700,0:01:05.120 | The active sensor area is now limited to this steel grid, |
| 01:05.120,0:01:09.540 | which protects the Geiger-Müller pancake. |
| 01:14.700,0:01:21.880 | The counter can measure in counts per second (cps) or counts per minute (cpm). |
| 01:24.580,0:01:27.960 | Now, let's put on the ambient lid. |
| 01:27.970,0:01:30.560 | There is a marking on the lid for guidance. |
| 01:30.560,0:01:34.560 | Put the lid on and turn to lock. |
| 01:34.560,0:01:38.610 | As you can see, the lid changes the quantity and the measurement unit. |
| 01:38.610,0:01:44.040 | Now, we measure ambient dose equivalent in Sievert (Sv). |
| 01:44.040,0:01:46.460 | Same here with the unit settings. |
| 01:46.460,0:01:48.760 | Press the up button three times. |
| 01:48.760,0:01:52.720 | I change from Sievert to rem. |
| 01:54.780,0:01:56.760 | When you're done with your measurements, |
| 01:56.760,0:02:00.880 | be sure to store the instrument with the lid on for protection. |
