7.6.5 Check Dark Current
1. Prepare (Refer 7.6.1).
2. Press 7 to select Utility.
3. Press “▲”, “Print”, to select diagnostic menu (Note: Sometimes this

4. Press 5 to select “Check Dark Current” (even if “Check Dark Current” is
not displayed). A table of Gain, Energy, will be produced (The minimum
at Gain 0 should be greater than or equal to 1. The maximum at Gain 10
should be 2000 to 4000).
7.6.6 Check Energy Profile
1. Prepare (Refer 7.6.1).
2. Press 3 to select “WL Scan”, press “F1” to setup, set the parameter as
follow, press “Enter” to finished setup.
Scan from: 1100
Scan to: 190

4. The wavelength will go to 1100nm and the energy profile will be
produced.
5. Record the maximum value around 550nm (25% to 60% full scale).
Record the maximum value below 340nm (5% to 10% full scale).
(For 2nm bandwidth, the energy will be approximately half these values)
