If the checks above are all satisfactory but still no peaks are obtained, possibly the settings of trimmers VR1 and VR2 are seriously wrong. In this case, turn VR1 while monitoring the low mass numbers m/z18 and m/z28 to obtain equal peak amplitudes. If this adjustment is not possible even by fully turning VR1, switch JP1 and attempt the adjustment again. Repeat the adjustment with 1) JP1 unshorted, 2) 1 to 2 shorted, and 3) 2 to 3 shorted. If equal peak amplitudes are achieved, conduct fine adjustment of the trimmers using the tool software.
这里的VR1和VR2指的是RF上的两个DIP吗？JP1在哪里呢；另外就是这个操作不懂： 1) JP1 unshorted, 2) 1 to 2 shorted, and 3) 2 to 3 shorted
