6. Troubleshooting
At first, please carefully read the previous parts of this manual, especially Safety instructions. If a problem
persists, please check the information given below.
General Test Procedure
Check:
•
Whether components of your IR detection kit are connected correctly,
•
Whether connections are snug-tight,
•
Whether supply voltages or currents of the components are consistent with the specification,
•
Attenuation/gain factors in your measurement set-up,
•
Load resistance at the preamplifier output,
•
For high frequency output line and the load must be matched to the 50 Ohm preamplifier output,
•
Whether bandwidths of the components are reasonably well-matched to each other,
•
Whether the detector is not saturated or damaged by too high irradiation,
•
Cycle the power of the components off and on again,
•
After shielding/switching off the radiation source, do you see any signal decrease? If yes, most probably you
see a signal from the optical radiation you hope to see,
6.1. List of the possible faults and solutions
6.1.1. Too high DC level at the output of the preamplifier
Follow through General Test Procedure.
Remove the IR source from the detector field of view or decrease incident beam power of your IR source. If
device still has high DC level, contact your technical support.
6.1.2. Too high current consumption by the preamplifier
The device is probably damaged, contact your technical support.
