LR-24
BACKPACK ELECTROFISHER
If you select more burst pulses than possible at the
selected cycle frequency (the low frequency), the LR-24
will automatically increase the burst frequency (the high
frequency), to allow the selected number of pulses to be
output. The LR-24 will not allow users to choose a burst
frequency that is too low to produce the number of pulses
that have been selected at the cycle frequency selected.
The following example demonstrates how to set up a Burst
of Pulses:
1. Press the Pulse Type key on the front of the LR-24. Use
the Arrow keys to select Burst of Pulses for the new
pulse type. The display will look like
Figure 2.25
.
2. Press the Enter key.
3. Press the Volts key and use the Arrow keys to set the
voltage (
Fig. 2.26
), then press the Enter key.
4. Press the Freq. key and use the Arrow keys to set the
cycle frequency (
Fig. 2.27
), then press the Enter key.
5. Press the Duty Cycle key and use the Arrow keys to set
the number of pulses (
Fig. 2.28
), then press the Enter key.
6. Use the Arrow keys to set the burst frequency (
Fig.
2.29
), then press the Enter key.
7. Use the Arrow keys to set the duty cycle of the burst
pulses (
Fig. 2.30
), then press the Enter key.
8. You can now use the Arrow keys to review the settings
for the burst of pulses (
Fig. 2.31
).
