My oscilloscope vertical axis dose not go above half of the screen, it only works right for a few second than it drops below middle of the screen any one had issues like that? |

Hi! The Metermaster 65601 Oscilloscope is a clone/rebadged version of the Aron BS–601 and an instruction manual with theory of operation notes, parts lists, adjustment notes, layout and circuit diagrams can be downloaded from k04BB! http://www.ko4bb.com/manuals/77.101.201.133/Aron_BS-601_20_MHz_Oscilloscope_Operator_Manual.pdf Chris Williams |

I turned pretty much every adjustment pot no change https://youtube.com/shorts/W2Qd8UkSy7Q?feature=share |
| Grandchuck:
The manual on page 23- shows the vertical output circuit. Check the supply voltages and then work backwards from Q17-Q20. |
