INCORRECT
Clamp too wide and overstepping on the signal low-to-high transition.

CORRECT
Clamp equal to 0.6ms and not overstepping on the signal low-to-high transition.
Figure 5–7 – Clamp signal Oscillogram # 3
If the adjustment of the clamp is bad because the clamp is overstepping on the low-to-high transition
of the detector signal, it is still possible to adjust the clamp by modifying the position of the optical
forks.
In this case, it is necessary to control the adjustment of the sampling.
Also check that the motor speed is adjusted correctly.
The clamp position should be in accordance with the data sheet delivered with each analyzer.
