The fiber optic link system also allows the meter and probe to be
separated by up to 50 meters. One application is surveying
towers. A skilled climber carries the probe while the person
actually making the measurements remains on the ground.

Setting the Meter
The meter has two input ports to receive information from
probes:
•
The standard probe cable input
•
The fiber optic receiver input
Only one input can be in use at any time. The default input upon
turn-on is the last input port used. It is important to remember
this if you switch back and forth between using the standard
input and the fiber optic receiver.
