If single point measurements are carried out with the sensor head OFV-512,
one of the two fibers must be terminated with a reference head. The reference
head is marked with a red dot. Always mount the reference head to the refer-
ence fiber, also marked with a red dot.
As default each sensor head OFV-512 is delivered with the reference head
OFV-151. The reference head is exactly adjusted to its sensor head. There-
fore each reference head has a own serial number which is noted in the
examination protocol.
Optionally you can use the reference head OFV-152 with adjustable stand-off
distance. You will find information on this in section B.1.

To mount the reference head OFV-151 onto the reference fiber, proceed as
follows:
1. Unscrew the mini sensor from the reference fiber and keep in a safe place
because each mini sensor is exactly adjusted to its fiber.
2. Screw the reference head onto the end of the fiber until it is securely fixed.
The reference head can now be used.
