Product Description

The Voltmeter is a compact and reliable device designed for accurately measuring DC voltage in various applications. With its user-friendly design and clear LED display, it provides instant voltage readings for quick diagnostics and monitoring. Here's a detailed description:

  • Physical Dimensions: The voltmeter features a compact size of 48 x 29 x 22 mm (LWH), making it suitable for installation in tight spaces. The opening size is 45 x 26 mm (L*W), allowing for easy mounting.

  • LED Display: Equipped with three 0.56-inch LED digital tubes, the voltmeter offers a clear and bright red display for easy viewing of voltage readings. The display color enhances visibility even in low-light conditions.

  • Measurement Range: The voltmeter has an input range of 7V to 100V, allowing it to accurately measure DC voltage within this range. It is capable of displaying voltages from 7.0V to 100V with a measurement accuracy of ± (1% + 1 Digit).

  • Update Rate: The device has a fast update rate of about 500 ms per measurement, ensuring real-time monitoring of voltage fluctuations.

  • Power Supply: The voltmeter does not require an external power supply for operation. It draws power directly from the circuit being measured, simplifying installation and reducing wiring complexity.

  • Temperature Range: Designed to withstand varying environmental conditions, the voltmeter operates within a temperature range of -10°C to 65°C, making it suitable for use in a wide range of applications.

  • Wiring: The voltmeter features two lead wires with a length of 14 cm each. The red wire is connected to the positive terminal (+) of the power supply and the voltage being measured, while the black wire is connected to the negative terminal (-) of the power supply.

The Voltmeter operates by utilizing the principles of voltage measurement to provide accurate readings of DC voltage levels. Here's how it works:

How the Voltmeter Works ?

  1. Voltage Sensing: The Voltmeter is equipped with sensing components, typically voltage-sensing circuits or voltage dividers, that are connected to the input terminals of the device. When voltage is applied across these input terminals, the sensing circuitry detects and measures the voltage level.

  2. Signal Processing: Once the voltage is sensed, the measured voltage signal is processed by internal electronic circuitry. This circuitry may include amplifiers, filters, and analog-to-digital converters (ADCs) to condition the voltage signal and convert it into a digital format suitable for display.

  3. Digital Display: The processed digital voltage signal is then displayed on the Voltmeter's digital display. The display usually consists of LED or LCD segments that illuminate to represent the measured voltage value. The display may also include additional indicators or symbols to convey information about voltage polarity, measurement units, or device status.

  4. Calibration and Accuracy: Before deployment, Voltmeters are typically calibrated to ensure accuracy and reliability of voltage measurements. Calibration involves adjusting the internal circuitry or applying correction factors to compensate for any inaccuracies or deviations in voltage readings.

  5. Power Supply: In some cases, Voltmeters may require an external power supply to operate. However, many modern Voltmeter designs, especially those designed for portable or low-power applications, are self-powered and do not require an external power source. They draw power directly from the voltage being measured or incorporate internal power sources such as batteries or supercapacitors.

Frequently asked questions (FAQ):

  1. Q: What is the input voltage range of the Voltmeter?

    • A: The Voltmeter has an input voltage range of 7 to 100 volts for accurate measurement. It is important not to exceed the maximum input voltage to prevent damage to the device.
  2. Q: Is the Voltmeter suitable for automotive applications?

    • A: Yes, the Voltmeter is commonly used in automotive systems to monitor battery voltage, electrical circuits, and charging systems. Its wide input voltage range and compact design make it ideal for automotive use.
  3. Q: Can I use the Voltmeter to measure AC voltage?

    • A: No, the Voltmeter is specifically designed to measure DC voltage levels. Attempting to measure AC voltage with this device may result in inaccurate readings or damage to the device.
  4. Q: How accurate is the Voltmeter's measurement?

    • A: The Voltmeter has a measurement accuracy of ± (1% + 1 Digit), ensuring reliable and precise voltage readings within the specified range.
  5. Q: Does the Voltmeter require an external power supply?

    • A: No, the Voltmeter does not require an external power supply as it draws power directly from the voltage being measured. However, it is important to ensure that the minimum input voltage requirement of 7 volts is met for accurate operation.
