Hovering the mouse pointer over the source status box will bring up a message describing the
current source status in more detail.
In the above example, the source message states that the source is operating normally.
The possible source states that may occur are explained in more detail below. This is also found
in the help file of the IsoPrime100 tune page.

Further Information
0
Operational
Normal Operation
1
High Trap Voltage
Trap voltage > 23 V. Trap circuit malfunction.
2
Low Trap Voltage
Trap voltage 1-17 V. Excessive trap current or leakage, particularly in
combination with low filament current. Also trap circuit malfunction
3
No Trap Voltage
Trap voltage < 1 V. Trap to source short circuit or trap/filament circuit
malfunction
4
Emission Limit
Electron voltage> 6 V below requested value with > 5 mA of emission
current. Filament alignment or excessive trap current request
5
ADC Fault
Internal ADC voltage monitor test failure. Suspect voltage readings
of repeller, trap, electron voltages and power supplies, and current
readings of filament, trap, source and emission
6
Low Repeller
Repeller > 6 V below requested value. Repeller to source leakage or repeller
circuit malfunction.
7
High Repeller
Repeller > 6 V higher than requested value. Repeller to source leakage or
repeller circuit malfunction.
8
High Electron Voltage
Electron voltage > 6 V higher than the requested value. Electron energy
circuit malfunction.
