Hello I have a problem with 2c42 measure capacitance: capacitor 100nF is displayed as 1uF and 10nF as 100nF - for 10x greater then it is. Resistors and etc are ok

Please confirm whether the resistance test and diode test are normal.

我的2D72电容档也不能用，只能测量1UF以下的，也很准确。超过1UF不准，1UF---10UF能勉强测量差额大，11UF--100UF的就彻底胡乱给个数字，一点可靠性都没有。看来2000系列示波表存在通病。我的示波器查看1M方波还可以，不算太失真，超过1M的方波严重失真。
