Heayzoki Volt Amp Meter, Digital Voltmeter Ammeter, Dual Display Integrated Voltage Ampere Meter DC 0~100V 20A, Voltage Amperage Tester
Specification: Voltage Measuring Range 0~99.9V Resolution 0.01V(<10v)/0.1v(10~100V) Ampere Measuring Range 0-9.99-20A Resoluction 0.01A(<10A)/0.1A(>10A) Measurement rate 500mS/ times Measurement accuracy 1% (± 1 word) Minimum supply voltage +3.5V Maximum supply voltage + 30V Operating temperature -10 ~ + 65 Working humidity 10 ~ 80% (without condensation) Working pressure 80 ~ 106 kPa Sunlight exposure no direct exposure Note: Power supply voltage (non-isolation meter): DC3.5 ~ 30V (wide range), note: maximum input voltage should not exceed 30V, otherwise there is risk of burning The watch head of 20A _ built-in shunt Since a 24V battery may have a floating voltage of more than 30V after it is filled, it is recommended that the "no" supply it directly with 24V batteries In the following cases, it is strongly recommended that: isolation meter (isolation power supply meter) When two or more meters are installed in a device, they cannot be alone, independent, or isolated when power is supplied
Product Features
- instrumentos design: The meter head is a common design, i. e. the ground wire at the measuring end is interlinked with the ground wire at the power supply end (except the isolation meter).Esta mesa doble es compacta, pero tambien, la misma pantalla de visualizacion de pantalla, corriente
- With voltage calibration potentiometer: The meter head is equipped with voltage calibration potentiometer, current calibration potentiometer, if there is any error, you can calibrate it, because the error is absolute present.
- Ampere Meter Voltmeter: The voltage meter adopts the design of automatic movement of the decimal point.
- Performance: This meter has strong anti-interference ability and fast display refresh rate.
- The meter head uses a wide power supply range: DC3.5 ~ 30V (except the isolation meter), the power supply reverse connection will not burn.
