When the fiber optic cable is not connected, cover the cable and connectors with
the protective plastic caps supplied. This prevents dirt or other contaminants from
entering the connector and causing communication problems. See
Maintenance
of Fiber Optics
on page 10 for more information.
ELF/OFF/VLF
This switch activates and deactivates the HI-3638 as well as the selection of ELF
or VLF bands. LEDs indicate which band is selected.
In the ELF or VLF position the HI-3638 is powered by the internal 12 VDC
nickel-cadminum (NiCd) battery. To prolong battery life, set the switch to OFF
when not in use.
Charge
A 16-hour trickle battery charger is supplied with the HI-3638. The
battery charger can charge the HI-3638 or the HI-4416.
Slight overcharging up to 24 hours will not harm the battery; however, charging
the battery longer than 24 hours may degrade battery performance.
Ground
Connect GND to earth ground to establish a reference for the HI-3638.
Output
Connect an oscilloscope to OUTPUT to observe the waveform of the signal
driving the true RMS to DC converter circuit.
