如何调整AMPTD CAL功能

情况：调整幅度后IAW Para。
5-13（操作和维修手册），按“AMPTD CAL”将幅度复位到调整值之前。具体来说;
10 Vpp测量值为3.466 Vrms（规格3.536V±0.04V），逐步调整，一切都在规格范围内。
当按下“AMPTD CAL”时，输出电压降回到3.466 Vrms，并且必须从开始无限循环进行调整...问题：如何调整“AMPTD CAL”功能以正确保持规格，一次
你离开1Vpp / 1mVDCO调整程序？
（第5-13段）我按顺序完成了整个调整，但问题仍然存在。
对“服务组K”进行故障排除没有错误.P.S。
调整的第5-2页缺少在线手册。

  Situation:
After adjusting the amplitude IAW Para. 5-13 (OPERATING & SERVICE MANUAL), pressing "AMPTD CAL" resets amplitude to before adjusted values.

Specifically; 10 Vpp Measures out at 3.466 Vrms (Spec 3.536V ±0.04V), step by step adjustment is performed and everything falls within spec.  When "AMPTD CAL" is pressed, the output voltage drops back to 3.466 Vrms, and adjustments must be done from the begining, endless loop...

Question:
How do you adjust the "AMPTD CAL" feature to hold the spec properly, once you leave the 1Vpp/1mVDCO adustment routine? (Para 5-13)

I have perfomed the entire adjustment in order, and still the problem perstists.  Troubleshooting the "Service Group K" yeilds no faults.

P.S. The online manual is missing page 5-2 of the Adjustments. (I'm using a hard copy)
