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.
