Description: Feature:1. 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).2. 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.3. The voltage meter adopts the design of automatic movement of the decimal point.4. This meter has strong anti-interference ability and fast display refresh rate.5. The meter head uses a wide power supply range: DC3.5 ~ 30V (except the isolation meter), the power supply reverse connection will not burn. Specification:Features: 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). 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. The voltage meter adopts the design of automatic movement of the decimal point. 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. The meter head is equipped with five wiring, the connection is convenient, it is used to monitor the voltage of the battery, to grasp the voltage state of the battery in time, and to measure the voltage and current of other products. Specification: Voltage Measuring Range 0~99.9V Resolution 0.01V(<10v)/0.1v(10~100V) 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 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 Connection method: This meter is equipped with five lines, please find professionals strictly according to the following wiring diagram, if any questions, please feel to contact customer service: Meter head power supply: two-wire socket Fine _ black line: meter head power supply Fine _ red line: power supply to watch head is positive (note, the voltage between fine red and black line cannot exceed 30V) Isolation meter (isolated power supply): The meter head power supply end and the test end are completely insulated and isolated from each other, can share one power source in multiple meters, "no need" is worried about all kinds of interference problems caused by sharing the power supply, suitable for the factory aging test stand, test stand, or other equipment requiring more than one meter head Power supply voltage: DC8-18V Test end: COM: Test Common End V +: Test positive voltage input A +: Test "positive" current input end;Because the meter head adopts the common ground design, that is, the ground wire at the measuring end is connected with the ground wire at the power supply end, so it can only be connected between the negative and the negative power supply of the equipment under test, as shown in the following figure, the connection error will burn, (if only do voltmeter use, it is recommended to connect the yellow line with the black line, Prevent the digital flicker of ammeter caused by external interference) Non-shunt _ connection method: suitable for "below 20A" without external connection.
