The product comes with electric stimulus grid with the intensity range of 0-5mA. It can be turned on/o  manually. In case of animal fatigue, it is turned o  automatically. The stimulus can e ectively force animal to run.

  • Individual Lane Counting

Each lane has a separate counting. Each lane has a separate button in the front of the treadmill track. Start the experiment, put the animal in its lane and then press the button. Once the lane button is pressed, the lane counting starts. After all lanes start, the experimental total time counting starts. When a lane reaches the total time, the system beeps. When the last started lane reaches the total time, the treadmill stops running.

 

The result output include:

  • Lane Num
  • Distance in meter
  • Duration
  • Shock count
  • State
  • Animal Fatigue Alert
  1. Shock number mode: There is a label Warn on the screen. When Warn=OFF, the function is off. Warn values range from 2 to 500. For example, when Warn=30 and shock count reaches 30, the electric stimulus in the lane is turned off.
  2. Shock duration mode: There is a label Shock on the screen. When Shock=OFF, the function is off. Shock values range from 2 to 25. For example, when shock=10 and shock continues for 10 seconds, the electric stimulus in the lane is turned off.

When one of the above two condition occurs, the animal is considered fatigue, the lane animal state on the left screen becomes “Alert”.

6. Training

Necessary training may be required for animal to be familiar with the treadmill. The training method can be as follows:

  1. Power on treadmill, set speed 5m/min, 10m/min, 15m/min respectively, and trial time 3-5 minutes. Electric stimulus is set to 1.0-2.5mA for Rats and 0.8-1.5mA for mice. Then start experiment and turn on electric stimulus.
  2. After step 1 training, put animal in the lane and press the button of each lane to start counting
  3. Observe the movement of experimental animals, according to the need for repeated training or speed training.

7. Precautions for experiment

  • In case the animals stay in the electrical stimulation area and does not exercise, it may be the animal in which the electric rod with the same polarity stimulus.

Through the sound stimulation or artificial drive, the animal can be forced to move to achieve the stimulus effect.

  • In the course of the experiment, if it occurs that the animal tail is tangled in the individual animals exercise capacity, or the spacing between the cover and the treadmill belt clip, the experimenter can terminate the running of the treadmill by pausing or stopping the experiment.
  • Regular cleaning of equipment, including belts and electrical stimulation areas, is needed to achieve the best experimental results.

Warning: Please power off before cleaning the equipment.

  • Due to the mechanical structure and motor component, noise may appear during operation, which is a normal noise. The noise can be eliminated by maintenance, or contact the manufacturer.
  • We recommend, after running 200 hours, to have a maintenance – cleaning the transmission parts plus lubricating oil.
