Using the HI-3616 Fiber Optic Remote Control
Electric Field measurements with the HI-3604 often require that the instrument
user be isolated from the instrument to avoid perturbation of the ambient field.
This is especially so in the case of the electric field component. In other
situations, the meter may need to be oriented such that it is difficult to observe
the Liquid Crystal Display (LCD) on the front of the meter. In these
circumstances, the HI-3616 Fiber Optic Remote Control is invaluable for remote
reading of the HI-3604 display.

HI-3616
To conserve battery life, the HI-3604 does not normally generate the optical light
beam necessary for operation of the HI-3616 Fiber Optic Remote Control. The
HI-3604 is normally in a "listening" mode. It is continually looking for a signal or
command from the HI-3616. In this manner, it is saving power by not having to
use its fiber optic transmitter unless actually communicating with the HI-3616.
When turned on, the HI-3616 is programmed to send out short "information
request" commands. When such a command is received by the HI-3604, it
responds and sends data.
The communications between the HI-3604 and the HI-3616 are bidirectional, i.e.,
commands and information travel in both directions. Take care when connecting
the fiber optic cable to match the meter and readout connector colors (yellow to
yellow; white to white).
The HI-3616 is able to control all operations of the HI-3604 from its control panel
in addition to displaying the measured field values.
Section 2.0
Maintenance
provides instructions on replacement of batteries for the
HI-3604 which also apply to the 3616. Please note that the low battery symbol
indication on the HI-3616 display refers to the battery condition of the HI-3604.
The HI-3616 battery life is significantly longer than that of the HI-3604; when the
display of the HI-3616 no longer responds; replace both batteries.
The data link between the HI-3604 and the HI-3616 is a plastic fiber cable. While
the fiber optic cable is generally very durable, avoid sharp bends in the cable and
avoid placing the cable under tension (do not pull on it). Because the data is
transferred by light pulses, the ends of the cable must be kept clean and
undamaged. Use the plastic caps provided to protect the cable ends when not in
use.
With the HI-3616 connected and operating, the ELF meter may be located as
required for a reading and the value measured observed on the display of the HI-
3616. When characterizing exposure the HI-3604 may be positioned at various
locations without interference from the instrument user (surveyor).
