HT-2000 Battery Backpack Electro-fisher
Nov. 2009 HT-2000 Manual 3
Controls and Features
All of the HT-2000's controls, except the emergency shut off switch (ESO) and
anode pole switch, are located within the watertight pelican case. The front panel
displays, controls, and connectors are shown on page 6 and described below.
Halltech’s new anode design is very different from historical anode designs. The
HT-2000's anode is a telescoping pole that allows the anode to be reduced to half its size
to allow for easier transportation and storage. It may also be adjusted to a comfortable
length based on the operator. The anode ring angle is also adjustable. If desired we also
have an anode pole that comes equipped with a crutch style handle. This crutch style
handle allows the user to grasp and hang on to the anode with greater ease. There is also
an area on the handle where a strap can be added to reduce fatigue to the users arm. The
switch on the anode is the last of three safety switches; the anode switch must be
depressed in for the unit to produce an output voltage. The output voltage switch is
located in the middle of the unit on the far right side. The output voltage ranges from 50-
950 V in 11 steps (50, 100, 150, 250, 350, 450, 550, 650, 750, 850, 950V). 50 to 350
volts is typically used in high conductivity waters (>300 microsiemens). 450 to 750 volts
work best in moderately conductive waters (100 to 300 microsiemens). 850 and 950
output voltage should typically only be used in low conductivity waters (less than 100
microsiemens). Increasing the output voltage just one step may increase the output peak
wattage 100% plus or minus depending on the conductivity on the water and the voltage
setting.
The Frequency [Hz] switch is located in the middle of the unit on the far left side
of the panel. The output frequency is in a range from 5-250 Hz in 11 steps (5, 10, 20, 40,
60, 80, 100, 130, 160, 200, 250Hz). The frequency is best described as the number of
times the fish is shocked in a given time period, or the number of pulse waves produced
each second. When first shocking a new site start with the lowest frequency setting.
Gradually increase the frequency until the desired effect is achieved. For example when
shocking a water body with a high conductivity (> 300 microsiemens) at an output
voltage of 150 volts and a frequency of 60, if you are rolling some fish but feel you aren't
getting all of them, try increasing the frequency to 80 or 100 Hz before increasing the
voltage to 250 V.
The Multifunction Meter switch is located directly in the middle of the panel.
The multifunction meter readout is located at the top right of the panel. The
multifunction meter can display mean current in Amps (xx.x display), peak power in
Watts (xxxx display), and battery voltage in Volts (xx.x display). The battery voltage
option is very useful for checking the level of charge of the battery being used. The peak
power option displays how many peak watts the unit is producing. This is also useful
because the unit will automatically overload when this value becomes too high.
To indicate if a feature has been activated the HT-2000 has been equipped with a
series of LED lights located near the top of the panel. The Overload Function enables
the unit to automatically shutdown and sound the tone alarm when the output power
becomes excessive. The LED light located at the far left will light up if an overload has
occurred. You must use a lower output voltage or frequency if an overload occurs. To
reset the overload LED you must push the front panel reset button, or cycle power with
the ESO button or the on/off switch located on the panel.
