Chapter 5 Maintenance
There are no serviceable parts in the PDA10DT detector or power supply. The
housing may be cleaned by wiping with a soft damp cloth. The window of the
detector should only be cleaned using isopropyl alcohol and optical grade wipes.
If you suspect a problem with your PDA10DT, please contact your local Thorlabs
technical support office and a member of our support team will be happy to assist
you.
Chapter 6 Troubleshooting
Problem
Suggested Solutions
There is no signal response.
Verify that the power is switched on and all
connections are secure.
Verify the proper terminating resistor is installed if
using a Voltage measurement device.
Verify that the optical signal wavelength is within
the specified wavelength range.
Verify that the optical signal is illuminating the
detector active area
Ensure, not to block, limit airflow to or stop the
cooling fan. It will overheat the devise and it will
affect its functionality.
Output Voltage will not increase.
Detector Output is skewed.
Check to make sure the detector is not saturated.
Refer to the Output Voltage spec. in the
Specifications table.
Install a 1" Lens Tube (SM1L10) to the thread
coupler (SM1T1) to baffle any external light
sources to see if this improves the response.
