Embodiment
The utility model is described in further detail below in conjunction with embodiment, but structure of the present utility model is not limited only to following examples:
[embodiment 1]
As shown in Figure 1, adopt the calibrating/calibration platform of laser localized light comparing indication test point, comprise test board 2, a side is provided with laser localized light comparing 4 on the test board 2, and its transmit direction points to the opposite side of test board 2.
The laser localized light comparing 4 of the present embodiment is the planar laser device, and laser localized light comparing 4 utilizing emitted lights are vertical plane.
The principle of work of the present embodiment is: test board 2 is placed in the radiation field of radioactive source, drawing straight line from radioactive source can be the straight line that draws, also can be that long rope is to test board 2 places, and so that the radiative exit direction of laser localized light comparing 4 is perpendicular to straight line, be that the light beam that sends of laser localized light comparing is vertical with the incident direction of radioactive source ray, then test.At first standard meter is placed on the test board 2, laser localized light comparing 4 irradiates the light of straight line type at standard meter, mobile standard meter, so that the central point of standard meter is located on the straight line that laser localized light comparing 4 irradiates, record the reading on the standard meter, setting this reading is standard value, after taking off standard meter, to treat that calibrating/calibrated meter is placed on the test board 2, and the mobile calibrating/calibrated meter for the treatment of, so that its central point also drops on the straight line that laser localized light comparing 4 irradiates, when instrument readings is stablized, read and wait to examine and determine/reading (reading at least ten numbers averages) on the calibrated meter; Repeat said process (selecting respectively three points fixing apart from radioactive source), carried out the measurement of three points after, examine and determine waiting/reading and the standard value of calibrated meter compare calculating and treat to judge whether calibrating/calibrated meter qualified.
