LR-24
BACKPACK ELECTROFISHER
CUSTOM SETUP PROCEDURE
USER-SELECTED SETTINGS
This procedure allows operators to select settings for
electrofishing. The proper procedure involves selecting the
waveform or pulse type, voltage, frequency, duty cycle, and
power limit. See section on Burst of Pulses Waveforms (page
32), if this is to be the selected pulse type.
Refer to the procedures (1-4) in the setup section (page 25).
1. When you turn on the LR-24, it recalls the waveform setting
that was in use when the LR-24 was previously turned off.
Check the waveform setting by pressing the Up arrow until
the waveform is displayed. If you were previously using the
LR-24 in Dual Output mode, the displayed waveform is the
primary waveform. Pressing the Up arrow again will cause
the secondary waveform to be displayed. If Dual Output
mode is not in use, then pressing the Up arrow the second
time will display the first status screen. If the displayed
waveform is not the setting you wish to use, continue with
the next step; otherwise, begin electrofishing.
2. Press the Pulse Type key and then use the Arrow keys to
set the waveform you want to use (Fig. 5.10). If unsure,
set the pulse type to standard pulse. Press the Enter key.
3. Press the Volts key and use the Arrow keys to set the volt-
age you want to use (Fig. 5.11). If you are unsure of what
voltage to use, set the voltage to 100V.
4. Press the Enter key.
5. Press the Freq. key and use the Arrow keys to set the
frequency you want to use (Fig. 5.12). If you are unsure
what frequency to use, set the frequency at 30Hz. Press
the Enter key.
6. Press the Duty Cycle key and use the Arrow keys to set
the duty cycle percentage you want to use (Fig. 5.13). If
you are unsure, set the duty cycle to 12%. Press the Enter
key.
7. Press the Power Limit key and use the arrow keys to set
the maximum average power you want to put into the
water (Fig. 5.14). If you are unsure what value to use, set
the power limit to 400 watts. Press the Enter key.
