Dear Sirs,
I have purchased your kit “Multi Functional Clock Display – K8009”. I have assembled the kit and it works ok. However I tried to calibrate the clock time base using CV1 (Time Calibration) and using a frequency tester the maximum period I can measure is 15623.493 microseconds and the lower one is 15619.952 microseconds. In both measurements I have a difference of a +0.45 additional second per hour. I followed all the instructions but can not calibrate it to be more accurate. I would appreciate your help to know how to achieve better results. I am very pleased in general from all your kits. This is not the first kit of yours that I assemble and all until now have been very good.
I thank you in advance for your assistance. Looking forward to your reply.
Marios Andreou
