LR-24
BACKPACK ELECTROFISHER
SYSTEM MENU 3 : DUAL OUTPUT
Dual output on/off allows the user to turn dual output
mode on or off (
Fig. 2.8)
. Dual output mode allows
the user to set up and switch between two completely
independent sets of waveforms and voltages by simply
releasing and pressing the anode pole switch in less than
1 second. The primary waveform and voltage, the one
entered first is the one activated when you press the
anode pole switch the first time. The secondary waveform
and voltage is activated by releasing and pressing the
anode pole switch in less than 1 second. This feature
allows the user to change voltages and waveforms quickly.
This can help reduce injuries to adult fish when collecting
young of the year, or when using a low frequency
waveform to get catfish to move off the bottom and then
quickly changing to a higher frequency waveform to
collect them. Any combination of pulse types, voltages,
frequencies, duty cycles, and power limits may be used
for the two outputs in dual output mode. To see or make
changes to either the primary or secondary waveform
from the main status waveform screen, press the Up
arrow key until the display shows the primary waveform.
Make changes using the Volts, Freq., and Duty Cycle keys.
Pressing the Up arrow key one more time will display the
secondary waveform and you may make changes to it in
the same way the primary waveform was changed. To
change back to the primary waveform, release the pole
switch for more than 1 second and then press it again. See
pages 33-34 for more information on Dual Output.
SYSTEM MENU 4: POWER LIMIT MODE
This menu item allows the user to select the method for
controlling the maximum average output power of the
LR-24 (
Fig. 2.9
). If the user-set power limit is reached, the
LR-24 will automatically decrease the output voltage or
frequency, as selected by the user, to maintain the output
power at that limit. If the output power drops below the
limit, the LR-24 will automatically increase the voltage or
frequency back to the user set value.
