detector range 5973 vs 5975

Just a quick question. On my 5973 I am trying to fix I notice the detector maxes out about 5-10E6 counts. On my 5975 the detector maxes out at 3.5E7 counts. Is that normal?

They each came in several flavors and with different software so I would expect different clipping thresholds.

I have had E^7 counts before on 5973's so could be software/firmware versions or possibly EM volt settings, the higher you have to run the EM volts the less linear dynamic range you will have.
I like to try an keep my normal calibration range at a max peak height in the 1 million range just so when I have high junk in the background I still have good peaks for the targets without far of clipping right when a target elutes.

Yea I'm running it a lot this week and the sensitivity seems pretty similar to my 5975 which has a very old (OEM 12 years) detector that runs at 1900ev. The difference in scale kind of threw me off while I was diagnosing it but reviewing old data that is normal for that instrument.
