LR-24
BACKPACK ELECTROFISHER
SYSTEM MENU 6: ANODE-OUT-OF-WATER DISABLE
Allows the temporary override of the Anode-Out-of-Water
feature (
Fig. 2.12
). This option allows the LR-24 to be used
in very shallow water, where it may not be possible to keep
the anode in the water all of the time. This option is only
active while the LR-24 is powered on. The mode resets to
“Enabled” on the next power up. Please see page 21 for
more information.
SYSTEM MENU 7: EXTENDED SYSTEM TEST
This is a diagnostic test mode for test and service
technicians. It requires the use of a standardized test load
connected to the anode and cathode.
During the test, the LR-24 checks its program memory
for errors, then it checks the operation of the output
safety relay, the output switch (IGBT), the accuracy of the
five internal voltage ranges, estimates the charge in the
battery, and measures the efficiency of the high voltage
converter. This test takes approximately 20 seconds to
run. To run the test, follow the instructions on the screen.
(Figure 2.13)
.
The user must press the Up arrow key to continue the test.
Pressing any other key will abort the test and return to the
status display
(Figs. 2.14-2.15)
.
Followed in a few seconds by the screen in
Figure 2.18
.
If the relays and regulation pass the test, the following
message will appear on the display, indicating the first
series of testing passed
(Fig. 2.17)
.
The next part of the test requires that the output of the
LR-24 be connected to a test load or that the electrodes
be in water. This part of the test takes about 15 seconds to
complete. When it is finished, the output of the LR-24 will
automatically turn off.
If the LR-24 passes this part of the test this message will
be displayed.
(Fig. 2.18)
This information is displayed for as long as the pole switch
is held down.
The use of a non-standard test load or electrodes in water
will probably yield different efficiency numbers.
