2-in-1 Multimeter High Precision LED Digital Volt Meter Panel, AC 100~300 V Dual Display Voltmeter Ammeter 0-100A (Red)

• Split type: easy to install, the transformer is separated from the instrument. The transformer can be installed according to the actual measurement position. The leads of the secondary end of the transformer can be extended to achieve the desired mounting position.
• No additional power supply required: a separate power supply is not required. If the red and the black cable are connected for voltage measurement, the meter can also be powered.
• Simple: no additional transformer is required for power testing. The instrument is equipped with a high-precision transformer. High quality.
• Calibratable: The type L trimmer potentiometer can calibrate the voltage and current errors yourself, making operation easier.
• Note: The use of the principle reduces the RC voltage. The higher the frequency, the smaller the impedance of the capacitor. Therefore, it is not suitable for high-frequency electronic speed control, non-urban electric sine wave frequency or other high frequency components, otherwise the gauge will burn.

Specification: The range of voltage measurement: AC100V-300V. Current measurement range: 100A (0.00 ~ 99.99A) Display mode: double 0.39 bright LED digital tube Display colour (optional): red + red / red + blue / blue + blue. Measuring accuracy: 1% ± 2 digits. Display: 0.39 inch LED tube display. Measuring speed: approx. 2 times per second. Dimensions: 70 x 40 x 30 mm. Installation dimensions: 68 x 38 mm. Mains module cable, test lead length: approx. 150 mm. Cable length of the "split" transformer: approx. 100 mm. Working temperature: -10 ~ + 50 °C. Working humidity: 10 ~ 80% (without condensation). Working pressure: 80 ~ 106 kPa. Sunshine: no direct exposure. Package contents: 1 x current voltmeter head. 1 x anti-inductance coil. 1 x adapter. Note: The wiring order of the instrument is: the circuit of the power loop is connected first, the 220V voltage is finally connected. After connecting the 220V power module, it cannot touch any parts and circuits behind the instrument to avoid the risk of electric shock. Split:Green terminal is connected to AC converter CT,two yellow wires are connected to measure AC voltage,do not connect incorrectly,connect incorrectly will cause device damage,the responsibility is yours. This meter is based on the principle of capacity reduction, as the impedance of the capacitor is the smaller the higher the frequency. Therefore, it is not suitable for use in high-frequency electronic speed controls for non-urban electric sine waves. Frequency or other situations where high frequency components are present, otherwise it can easily burn down! When selecting the range, the error is the larger the range. It is recommended to meet 1.5 times the actual test value.
