5 Changing Foreoptic Accessories
Your PSR Series instrument comes with a standard lens foreoptic installed. If you have
purchased additional foreoptic accessories such as fiber optic cable and 180° diffuser,
this section describes their installation.
Important:
Removing the factory-installed lens exposes the optical slit (see Figure 9). The
slit is extremely fragile; therefore it is important to take extra care when removing
and installing foreoptic accessories to avoid damaging it. Always keep a lens or
other foreoptic installed to protect the slit from dust, fingerprints, etc.
To install the fiber adapter, first, remove the battery from the instrument and place it on
a sturdy surface. Protect the lens by covering it with the supplied plastic cap. Unscrew
the lens foreoptic from the PSR by turning it counterclockwise. Remove from the PSR
and cover the opposite end of the lens barrel with a second plastic cap and store the
lens in a secure place.

Next, turn the PSR so the optical mounting area is facing upwards. Secure the
instrument so it is sturdy and locate the fiber alignment plug (Figure 8).
