I bougth a TO1112C (S/N: CN2241076000987)oscilloscope about 1 month a go. From the first day i have a self-discharce of the batteries, i tryied with 4 new Panasonic (3.4Ah) batteries but no change at all. My problem mentioned to Hantek also to Aliexpress( Meterk) , but no one really cares to help to find a solution. The oscilloscope has a hardware problem. Please tell me, where is the warranty of your products?I have a useless instrument in my hanfs and waiting for a respossible response fro you.
