❑ Press Manual Tuning and the Manual Spectrometer Tuning screen appears
(
Figure 7-7).
Use this screen to view and manually adjust the parameters of the ion source in the
spectrometer for a maximum helium signal.

Emission Current Displays the value of the existing Emission current of the spectrom-
eter Ion Source and allows for emission current adjustment. The
emission current parameter tunes the leak detector, maximizing the
leak detector output for a peak helium signal.
Typical Emission current values range from 0.6 mA to 1.2 mA.
Ion Voltage Displays the current ion voltage value of the spectrometer Ion
Source. The ion voltage parameter tunes the leak detector, maxi
-
mizing the leak detector output for a peak helium signal.
Typical ion voltage values range from 205 VDC to 240 VDC. The
ion voltage value is automatically adjusted and set during the full
calibration routine.
