Unstable frequency.

Hi, I would like your help, my DSO-150 is not stabilizing at the 1000khz frequency, it is giving 1112khz, perfect wave. But in other equipment it oscillates much the frequency and is running the wave. Just to hold or manual. It gets really bad in the car.
Now let's go.
Here we say, the Japanese reads the manual and buys the device, Europe and USA buys the device and reads the manual, the rest of the world buys the device and then throws out the manual and tries to find out everything later.
I'm part of this rest of the world.
Unfortunately I bought it on Aliexpress and I believe it is not original.
But I expect your judgments.
I was reading the forum and checked that maybe update would solve, but not being original would not have that possibility.
Again I appreciate the help.

I have this "problem" too, and the solution was to increase the Sec/Div value, making more waves come to the screen and giving more data to calculate the parameters.
