chrony m1 not detecting pellet

[MMoudk]

hello

today my chrony m1 not detecting pellet.why? everything is like before

i cannot see my issue in this list

C) PROBLEM: No reading after shooting. Cause & Remedy:

1. not using diffusers on blue sky, sunny day; add diffusers;
2. using diffusers on a cloudy day; remove diffusers;
3. unit too close to muzzle; move unit farther away;
4. not shooting directly over photocells; aim more carefully;
5. unit not properly aligned with bullet path; realign rifle to point directly at target; and,
6. shooting too early or too late (poor light conditions); wait for better light, or end chronographing session.

(Edit) Usually a lighting problem and looks like you are indoors they are very picky indoors. A light straight above each sensor is required. I use some cheap palm shaped led flashlights from Harbor Freight on top of the diffusers and never get errors.

yes it was indoor test , as always it was ok in indoor,i also tested at outdoor with diffusers but not read pellet.

 If it does not werq outside in the shade without the diffusers you have a problem. If the sensors are clean the battery is good and it is no longer werqing indoors or out. with lighting it has done well with before, I would guess it is in the electronics a loose wire, bad cable or sensor although the unit itself can die as well.

Maybe I’m wrong but from what I can tell in your video, the sensors are overwhelmed by the lighting. No shadow for the sensors to see. Shade the sensors a little or use lower wattage lights.

here is my chrony rig. I address the brightness issues in the video.

Less than 1% error read outs.

I had the same problem when I tried to use it inside. Adding lights above sensors did not help much. Checking around I found that the sensors are specific to a certain wavelength of light which is very low with indoor lighting. Most chrony manufacturers sell an indoor lighting kit which fits where the diffusers attach. After installing these special lights I have not had a bad reading in 5 year.
