4.0 Laser-Powered Field Probes
The HI-61XX Series LaserPro™ Field Probe is a laser-powered probe, an
excellent tool for electric field mapping, industrial monitoring, and EMC field
measurements.
The HI-61XX Series probes contain a photo-voltaic converter that provides power
to the probe circuitry when sufficient light power is received by the converter. The
light power is generated by a laser in the HI-6113 Laser Data Interface (LDI), and
is transmitted to the converter through an optical fiber in the duplex fiber optic
cable. The probe communicates with the HI-6113 through this fiber optic cable.
Receiving power from the HI-6113 allows for unlimited test times.
The probe system incorporates a safety interlock mechanism that turns off the
laser if the HI-6113 does not receive data from the probe within a specified time
frame. The safety mechanism is intended to prevent injury from the laser if the
HI-6113 issues a command to turn on the laser while the fiber optic cables are
disconnected, improperly connected, cut, or damaged.
The HI-6100 Field Monitor may also be used with the HI-61XX Series Field
Probe for RFI/EMC testing.
The basic probe is shipped with an attached one-meter fiber optic cable, a
10-meter fiber extension cable, a carrying case, a battery charger, and
connectors that extend the length of the fiber optic cable.
