5.3.1 Summary of Parameters
Optimizing
parameters in a
specific order
Changing instrument settings parameters can impact the
sensitivity, resolution, or signal-to noise ratio in different ways.
For optimum performance, optimize parameters in the order
listed in:
• Section 5.4.3, Optimizing Resolution
• Section 5.4.4, Optimizing Signal-to-Noise Ratio
List of parameters
The following table lists the impact of changing these
parameters.
Parameter Mode Impact
Delay Time
(nanoseconds)
Linear/
Reflector
Impact dependent on Grid Voltage%.
Performance drops off if set too high or
too low for corresponding Grid Voltage%.
May vary with matrix.
Critical parameter with optimum values
for maximum resolution.
Guide Wire Voltage% Linear/
Reflector
Decreasing improves resolution.
Increasing improves sensitivity for higher
mass.
