HM310T clock running fast

[Antuan]

Hi all,

Newbie here, a programmer from Spain learning some electronics.

Just picked up a HANMATEK HM310T from Amazon. Lots of interesting features there for me there, specially the memory for predefined outputs.

Works nicely, except one thing: this model has a timer/counter, which starts counting in seconds when you switch on the output. I noticed that it is running faster than it should, and I'm not sure why. See a video here: https://imgur.com/a/hzxpSm1.

Am I doing something wrong or shall I return it?

Thanks!
