Setting The Parameters - Leica EM TIC 3X Operating Manual

4.4.2.1 Setting the parameters

By pushing directly the parameter field (red arrow), the value of all three guns can be
changed simultaneously using the arrow buttons. This can be done for kV, mA and
time settings.
By pushing in the parameter field (blue arrow), the values can be changed for each
gun individually using the arrow buttons.
The optimum source current for the selected voltage is set automatically by
changing the voltage value. However, the current could be automatically tuned
by the software at different values as well. This could be necessary to stabilize
the guns at low kV settings if gun lifetime is more than 100 hours.
Each gun can be disabled or enabled by pushing directly on the gun symbol (green
arrow).
The disabled gun then fades to grey and is set out of operation.
