重复步骤5，6，7，8，直到拥有4个弹丸亮度值。4个值的均值即为有效弹丸出膛亮度值。

对于iphone13，有效弹丸出膛亮度值大于120为测试通过

对于iphone14，有效弹丸出膛亮度值大于125为测试通过

对于iphone15，有效弹丸出膛亮度值大于125为测试通过

Procedure Description

Illustration

1

Open Blackmagic Camera, go to Settings and choose HD as the resolution for recording videos.

Refer to the download link below for the Step-by-Step Guide for Self-test of 17 mm Fluorescent Projectile Brightness

2

Go to camera settings and set the lens to 13 mm, ISO to 64, shutter speed to 1,000, white balance to 4,500, hue to 15, and frame rate to 60 Hz.

3

Position the phone at a 1 m distance directly in front of the Speed Monitor Module's light indicator and record a 5-second video of continuously fired projectiles at the maximum radio frequency (the radio frequency must be limited to 20 Hz or below).

4

Randomly select 4 frames from the video, and these frames must contain projectiles exiting the muzzle and traveling 10-30 cm.

5

To obtain the image file path, open the computer's folder and locate the image. The path displayed in the top left corner plus the file name and extension is the image location.

6

Open 17mmBulletTest.exe and enter the image path obtained in Step 6 as instructed.

Note: Please enter the absolute path of the image and avoid any Chinese characters in the path.

7

In the opened image, box select a 17 mm projectile. Make sure the box is basically tangential to the projectile.

8

Record the value provided by the software.

9

Repeat steps 5, 6, 7, and 8 until you have four brightness values. The average of these four values represents the effective brightness value of projectiles exiting the barrel.

For iPhone 13, a brightness value greater than 120 indicates the test is passed.

For iPhone 14 and iPhone 15, a brightness value greater than 125 indicates the test is passed.
