digital voltage gauge boat
The boat voltage gauge , we have both needle type and digital type . Also we have boat gauge panel , which include the voltage gauge . The boat voltmeter is useful. Just connect the voltmeter in parallel with the consumer (12 V or 24 V). It is the voltage of the battery. Don't connect firmly before connecting. Try the direction of the voltmeter number with the connecting wire first. Just go up high and fix it. If you don't turn the two wire ends upside down. Be careful to move quickly, or you'll burn the boat digital voltage gauge. Determine the connection position according to whether you want to measure the battery voltage or part of the voltage, select the range and model of the boat digital voltage gauge , and select the appropriate position to fix the voltage gauge . The positive pole of the boat digital voltage gauge is connected to the positive pole of the line, and the negative pole of the voltmeter is connected to the negative pole of the line.
What is the range of the boat voltmeter? Are 12V and 24V universal? The installation size is the same, 24V can replace 12V . However, 12V cannot replace 24V, otherwise the meter will be broken . The boat digital voltage gauge can not only judge whether the voltage of the battery is normal , but also judge whether your acceleration dosage is appropriate (it is better not to accelerate too much) and how much energy the battery stores according to the voltage when driving. Especially when it is empty , the acid lead battery should be charged in time when the voltage is lower than the specified value , otherwise the battery life will be affected.
The zener diode in the boat digital voltage gauge has a protective effect, such as static electricity, thunder, etc., causing damage to other components. Its principle is overvoltage conduction discharge. If the voltage is normal, it will recover. If it is too high, it will be broken down and scrapped. It mainly tests the electromotive force of a power supply, while the ammeter cannot be directly connected to both sides of the power supply. If the ammeter is connected to both sides of the power supply, it is likely that the circuit will burn out and short circuit, which will also bring certain harm to people.
