10 dynamic range
12 outline drawing (mm)
Typical counting sensitivity for DM0089C at 400 nm. Note
that automatic dead time correction has been applied at high
count rates. The dynamic range can be further extended at
low count rates by dark count subtraction in the software.

13 installation and operation
counter
Each module is supplied with test data. Wherever possible
carry out installation in subdued light.
Remove the protective cap from the window of the module. If
necessary, clean the photomultiplier window using a lens
tissue moistened with alcohol. Do not use any other solvent.
Mount the module and make power input and signal
connections.
Do not expose the photomultiplier tube photocathode to
strong lights while the module is energised.
14 warning
Do not attempt to repair or dismantle this product. High voltage
used within the module presents an electric shock hazard.
Do not operate beyond the maximum ratings, or reverse the
input voltage; this may result in loss of performance or
permanent damage to the product.
