1. Preparation 1. Tools Wire stripper, electric pen (12V-24V), screwdriver (cross, straight), insulating tape, tool knife, double-sided tape, cable tie, and some other car removal tools (depending on the model). 2. Installation circuit diagram Read the installation circuit diagram and installation supplementary instructions carefully, and strictly follow the installation circuit diagram to ensure that after the installation is complete, the installation positions of the host, anti-theft host, antenna, and microphone in the car meet the requirements of the supplementary installation instructions. Second, the installation program 1. Confirm whether the original car has a central lock before installation If yes: determine which trigger form it is. When installing the anti-theft device, you can connect according to the "wiring diagram of the central control lock" in the "installation circuit diagram". Note: If the judgment is uncertain, connect according to the positive and negative trigger in the "Central Control Lock Wiring Diagram" to ensure that the central control lock works normally. If not: a central control lock is required. 2. Determine the installation location Remove the decorative panel at the lower end of the instrument panel to determine the installation position of the system host, anti-theft host, antenna and microphone in the car (be sure to meet the distance requirements of the installation supplementary instructions), pay attention to dust and waterproof. Lay a good foundation for distribution wiring. 3. Check the line, wiring, line layout Check the line: find out the required connection line in the installation circuit diagram Distribution line: When distributing the line, the wire should be concealed and beautiful as much as possible, and the distance between the contact and the host should be set a little longer. Wiring: Connect each one of the lines measured under the premise of ensuring no errors, to avoid wrong connection. Wiring requirements: The connectors are tightly connected to avoid virtual connection, and wrapped with insulating tape. This process is the most important step in the entire installation process. If the connection is wrong, the anti-theft device cannot be used at all, and the components in the car will be burned down, making the vehicle unusable or even causing a fire. 4. Method of line checking To connect this anti-theft device, you need to find out the following lines in the car: positive electricity, ACC, lock ON line, turn signal line, foot brake switch line, door side contact switch line, central control lock signal line. Positive electricity: Pull out the key, the electric pen is grounded at one end, and the other end is tested on the lock lead. The positive indicator light is always on when the indicator light of the electric pen is on. ACC line: Hit the lock key to the ACC and test it on the lead of the lock with an electric pen. The indicator light of the electric pen is on. After the key is turned off, the indicator light is off. This connection is the ACC line. Lock ON line: Turn the lock key to the ON position, test it with the electric pen on the lock lead, the indicator light of the electric pen lights, then start the engine, you will find that the indicator light of the electric pen will go out obviously, then light up again. Disconnect the following wire and the engine will stop. This wire is the ON wire. Turn signal line: Turn the key to the ON position and turn on a turn signal switch. Then use the electric pen to search on the harness under the turn signal switch (a small number of models need to be found near the fuse box). If the indicator light of the electric pen turns on and off with the turn on and off of the turn signal, this line is the turn signal line. Look for another turn signal wire. Foot brake switch line: This line is generally found at the contact switch above the foot brake. One is the normally-on positive electricity, and the other is that the electric wire that is only available after the foot brake is depressed is the foot brake switch wire. Door contact switch line: Open the door of the driver's seat and close the other doors. The clip of the electric pen is connected to the positive electricity in the car, and the other end is used to test the wiring harness of the door switch. Press and hold the contact on the side of the door with your hand to open and close. With the opening and closing of the contacts on the door, the indicator light of the electric pen and the lighting lamp in the car are turned on and off. This line is the door contact line. Central control lock signal line: The electric pen is grounded at one end, and the circuit in the wiring harness is tested at the other end (the wiring harness is generally near the door of the driver's seat). The test is repeated. The locks of the four doors are turned on and off as the electric pen instructions turn on and off. This is the signal line.
An aquarium thermometer, as the name implies, is a device used to check the temperature of the water in a fish tank or aquarium. This is important because fishes thrive in a certain environment, and this is easier to achieve with the help of a thermometer.
Using a digital thermometer is easy and doesn`t require many steps. Start by placing the probe that comes with the thermometer in the water and secure it with the suction cup. It is important to note that you shouldn`t put the monitor in the water, too, as this could damage it. Proceed to turn on the digital thermometer and apply it with the help of a suction cup.
