I am new at our ICP-MS 7700x and in the moment after tuning the forward power decreased from 1600 W to approx. 1200 W and the reflected power increased from approx. 10 W to approx. 110 W.
I have no idea why this happened and to fix it.
After Auto RF correction there is 1600 W again and when I start a batch it decreased again.
Can anyone help me please!
