3-type 50 m running test instrument infrared test wide screen lcd display voice reading

1 Function Introduction: Determines the development level of the subject's speed endurance, agility, and the flexibility of the nervous system.

2 仪器 features: can test 2 people at the same time, using infrared testing method, measuring the time from the starting point to the finish line, accurate and convenient

3 Preparations Before Use
 A host is placed on the starting line, extends the antenna, and the host requires an external power supply.
 Before the B test, place three test poles in the location, with two infrared transmission poles on both sides and an infrared reception pole in the middle (the test involves pulling out the antenna). The distance between the two poles should be 1-1.2 meters.
 Open the power switch for the test rod and the firing rod, and aim the infrared transmitting box's transmitting window at the receiving window of the infrared receiving box (Note: when aligned, the light goes out, cover the receiving window with your hand, and the light tube inside should flash for a moment. If not, adjust the position of both until the light tube flashes. Similarly, adjust the position of the transmitting box on the other side. When the two rods are within 1 meter of each other, if the light tube in the receiving window does not light up when you cover it with your hand, it may be due to the battery running out. In this case, you should replace the battery in time).
 Pull out the antenna of the launch box
4 Usage Instructions
 A operation should be carried out as much as possible according to the voice prompt.
 Subjects should wear athletic shoes or flat cloth shoes for running, and they are not allowed to wear spiked shoes, leather or plastic sandals.
 If C discovers a runner who has started before the start signal, the runner should be recalled and the race restarted. If there is a wind, all runners should run into the wind, and when running, they should be careful not to hit the test poles on either side.
 Please remember to turn off the D infrared transmitter and receiver at any time to save electricity (usually about 2 hours with new batteries).
 When the remote control distance is less than 50 meters, it is necessary to replace the remote control battery in the receiver box (the 9V battery is visible when opening the front cover of the receiver box).

Technical specifications: Measurement range: 0 to 999.9 seconds, resolution: 0.1 seconds, accuracy: 1.5%, with synchronous voice prompt function. Remote control distance greater than or equal to 50 meters.

Features: Determines the time taken to reach the finish line from the start, to assess the test subject's speed, endurance, agility, and the development level of their nervous system's flexibility.

Function: The single machine has the functions of query, anti-deletion, and student number increment. It is equipped with synchronous voice prompt, wide screen, Chinese LCD display, and uses infrared measurement methods for accurate and convenient testing.
