8.4. Fuse Replacement
To replace a blown fuse, use a flat head screw-driver to open the fuse door by twisting it counter-clockwise. Pull
out the fuse drawer, replace the fuse, then push the fuse drawer back in place and twist it clockwise using the screw
driver.
8.5. Proof Test System Maintenance
Check Proof Test Calibration/Recalibration
The proof test calibration must be periodically checked to ensure that the correct load is being applied to the fiber.
If the Proof Tester is applying a greater load than expected, the process yield may be adversary affected due to
excessive proof test failures. If the Proof Tester is applying a load less than expected, the proof tested section of
the fiber may be weaker than required and could fail at a later time.
Checking and re-calibrating the Proof Tester requires special equipment and training. Contact Thorlabs to learn
more about calibration options.
Replace Fiber Holding Block Inserts
Replace the top or bottom insert by loosening the four (4) set screws securing them in place with a 0.035" Hex
wrench. (One full turn counter-clockwise should be sufficient.) Remove the insert and clean the slot of the fiber
holding block. Refit the new insert into the slot and center it within the fiber holding block. Lightly tighten the set
screws while applying downward pressure on the insert. Excessive force is not required to hold the inserts in place
- do not over tighten.
