I have 6074be with reading error.
Can you help me please.
Is there an adjustment? how should I proceed?

Dear Sir,

Greeting from Hantek.

Please perform the self-calibration operation, the steps are as follow:
Disconnect all input connections of the oscilloscope→Utility→Calibration

Have a nice day.
