Combro chrono problem

Postby Cam » Mon Aug 26, 2013 1:02 pm

Please can someone help me.


I am trying to re-chrono my HW97KT.


The chrono has suddenly started to show "bad" after each shot. I have checked that unit is mounted centrally to bore line and the that it is secure When I remove the unit from the gun and drop a pellet through it, it reads ok.


Could the sensors need a clean? Any ideas?


Many thanks in advance

Are you working in good light? Outdoors in good light is good but indoors can be very problematic.

If its indoors must have the correct light source and plenty of it.
Fluorescent lighting is a definite no no! I use led sources on my Chrony F1 & they work fine.
Cheers,

Many thanks for the replies.

The matter is sorted, I am a dumb-ass.

I, in fact, had not centralised the unit with the bore. Robin at Combro talked me through how to test for various voltages and hey all checked out. It was whilst I was on the phone to him I suddenly saw that the unit was not centralised.

Thanks again.
