Dual Led 0.28 ” Display for DC0-100V Voltage and Current Test Digital Instrument Digital Meter Panel Amplifier Red Blue 10A
Introducing the Dual LED 0.28” Display for DC 0-100V 10A Voltage and Current Test Digital Instrument, a versatile and accurate digital meter designed for voltage and current measurements across a range of applications. The panel features dual LED displays—red for voltage and blue for current—allowing for clear, simultaneous readings for easy and efficient monitoring.
This digital voltmeter operates by converting an analog signal into a series of pulses, with the pulse count corresponding to the magnitude of the input signal. Using A/D conversion, it ensures precise and reliable voltage readings. The digital voltage display works on a binary principle, showing either 0V (off) or a peak voltage (on), such as 5V, for accurate measurement of electrical parameters.
Features:
- Dual LED display: Red for voltage, Blue for current (measured in the negative rail)
- Requires external power supply with reversed connection protection
- Ground wire of the testing end and power supply terminal is the same wire, ensuring quick refresh of about 500 MS/time
- Built-in shunt with voltage and current calibration potentiometers
- Suitable for automotive/electric cars/motorcycles battery monitoring and other voltage/current measurement applications
- Rapid response recovery characteristics
- Long life and reliable stability
- High precision, four-digit display
- Measures voltage: DC 0 ~ 100V
- Operating voltage: DC 4.5 ~ 30V
- Minimum resolution for voltage: 0.1V
- Minimum resolution for current: 10A
- Operating current: 20mA
- Display: Three 0.28″ LED digital tubes
- Mounting cutout: 45.5 x 26.5mm
- Refresh rate: Approximately 500mS / times
