Set the acquisition parameters for autotune or lens autotune in a custom tune.
No Gas Mode
[Mass 1] to [Mass 3]
Enter the masses for low, medium, and high masses for autotuning for in no gas mode.
Set the masses of Q1 and Q2.
When you select elements to use for hardware optimization, be sure that the chosen elements have a stable signal within the range of the pulse count detector mode. Note in particular that selecting an element whose signal is too high, too low or unstable can cause hardware auto-optimization to fail.
Gas Mode
H2/He Gas Mode
[Mass 1] to [Mass 3]
Enter the masses for low, medium, and high masses for autotuning for in a gas mode.
Enter the masses for low, medium, and high masses for autotuning for in a H2/He gas mode.
Set the masses of Q1 and Q2.
When you select elements to use for hardware optimization, be sure that the chosen elements have a stable signal within the range of the pulse count detector mode. Note in particular that selecting an element whose signal is too high, too low or unstable can cause hardware auto-optimization to fail.
[Deflect Tune Mass]
Enter the mass to use for autotuning the deflection lens.
3rd Cell Gas Mode
[Mass 1] to [Mass 3]
Enter the masses for low, medium, and high masses for autotuning in a 3rd Cell Gas mode.
Set the masses of Q1 and Q2.
When you select elements to use for hardware optimization, make sure that the chosen elements have a stable signal within the range of the pulse count detector mode. Note in particular that selecting an element whose signal is too high, too low or unstable can cause hardware auto-optimization to fail.
[Deflect Tune Mass]
Enter the mass to use to autotune the deflection lens.
4th Cell Gas Mode
3rd Cell Gas: Helium content of gas mix must be 90% or more; For example: NH3/He mix, He content must be equal to or greater than 90%; Even if introducing a non-corrosive non-flammable gas to the 3rd cell, it still must be diluted with 90% or more Helium.
4th Cell Gas: Use only non-flammable non-corrosive gas.
For important information and precautions on the handling and use of compressed gases (including oxygen, hydrogen and ammonia) refer to the Hardware Maintenance Manual, Ammonia Safety Guide, Hydrogen Safety Guide and Site Preparation Guide.
[Mass 1] to [Mass 3]
Enter the masses for low, medium, and high masses for autotuning for in a 4th cell gas mode.
Set the masses of Q1 and Q2.

Note in particular that selecting an element whose signal is too high, too low or unstable can cause hardware auto-optimization to fail.
[Deflect Tune Mass]
Enter the mass to use for autotuning for the deflection lens.
[Mass Balance]
Enter the percentage value for the mass balance in the text box or move the bar on the right to set the value. The mass balance is a parameter for weighting the sensitivity variation for the lens voltage with the mass in the lens autotune. As the value is smaller, the tuning shows better sensitivity for lower masses. As it is larger, the tuning shows better sensitivity for higher masses. Note however that when the sensitivity is high for lower masses, the off-mass background may increase. Usually, configure the setting so that Tl is two to four times more sensitive than Li.
Cool Plasma Mode
Enter the mass to use for autotuning in cool plasma mode.
[OK]
Applies the settings.
[Cancel]
Cancels the settings.
