4in1 Digital voltmeter Ammeter Thermometer powermeter 33V/3A+Free shipping With Track Number Description Products features: This meter has the perfect function and put four function of measuring the voltage, current, temperature and power into this one meter. when the current is measured, the power is firom the measurement circuit and it don't need the isolated power. so the current is easy to be measured. It has high precison in voltage measurement and voltage compensation in measurment circuit. it can automatically compensate voltage drop according to current size on the wire. This meter only contain the meter header and don't contain 18B20 temperature sensor chip and 18B20 temperature sensor with wire you can choose to but what you need. Technical Parameters: Weight: 23g Display color: Red+Red Red+Green Red+Blue Display mode: Dual 0.28 LED digital 4 bit tube update rate: About 200 ms/time Physical size: 48 x 29 x 26 mm (L*W* H) Opening size: 45 x 26 mm (L*W) Supplyvoltage: 3.5-28V Lead wire length: 14 cm(Five wires) Measurement range: DC 0-999.9mA-3.000A(current) DC 0.00-33.00V(voltage) -55 °c ~ 110 °c(Temperature) DC 0.9-99.9W (Power) Measurement accuracy: ± (0.3% + 2words) Display discription: Voltage current meter mode:Boot default display voltage current meter mode The above digital tube display voltage; there are four fixed display precision. the measurement range is 0.00-33.00V; the mimimum resolusion is 10mV The below digital tube display current; there are four fixed display precision; the measurement range is 0-999.9mA-3.000A. When the measuring current is below 1A, it display***.*mA,the resolusion is 0.1mA; When the measuring current is higher than 1A, it display*.***A,the resolusion is 1mA; Temperature power meter mode:Press the button one time, the meter is switched totemperature power meter mode. The above digital tube display temperature; there are three fixed display precision. The fourth bit is sign bit, displaying 'C'. The measurement range is -55 °c ~ 110 °c; the mimimum resolusion is 0.1°c. The below digital tube display power; there are three fixed display precision. The fourth bit is sign bit, displaying 'P'. the measurement range is 0.0- 99.9W; the mimimum resolusion is 0.1W . When the 18B20 chip is not inserted into the meter, the above digital tube display"-N-C". When the temperature exceeds the measurement range, the above digital tube display "---C". When the power exceeds the measurement range, the below digital tube display "---P". The voltage compensation function discription: When the system load is bigger, there will be some certain voltage drop on the connecting wire. So the header will not display the right output voltage of the system supply power. Now the voltage compensation function can solve this problem by moderate compesation of the voltage loss on connecting wire. So the meter can measure the precise voltage of the system supply power. When you use this function, you must prepare a more than four and half digit multimeter. Please connect it with the output piont of the system supply power, and then shut down the power of the voltage current. Then keeping press the button on the back of the voltage current meter and give the meter power at the same time. Now the below digital tube will display [**]; ** indicate the storage compensation voltage level(when the meter was just produced, the level is 00, display [00], meaning no compensation). when you loose the button, the below tube display --** When it displays --**, it indicates the meter is going in the state of setting compensation voltage. Please connect the the bigger load in the circuit( we advise the current of the load should be higher than 2A, so the compensation will be more precise.) ,then see the voltage which the above tube show. Pess shortly the button one time, it will be automatically added one level (The maximum commpesation level is 99), until the voltage on the meter is the same to the voltage on the multimeter. Keeping press the button more than 2s to store the current compension voltage. so you will measure the volage by this compensation level. If you want to shunt down the compensation, please adjust level to 00. Instruction of wiring Red thin wire (VCC):Power input+ 3.5-28V(NOTE: If the measuring signal is lower than 28V and have abundant power supply, it can be used as power supply for the module [black wire and yellow wire are contacted together to use]) Black thin wire(GND):Power input- Measurement signal - 3.5-28V Yellow thin wire (VIN):Measurement signal+ (0-33.00V) Red thick wire (I+):Current input+ (connect with load negative) Black thin wire(I-):Currentinput-(in series in power supply negative) Note:the connection instruction of temperature sensor, please refer to the back of product picture Wiring instruction: Voltage current meter with isolated power supply Package include: 1 x meter If color required, please indicate the color, if not stated, we will randomly grant Payment Method We accept only Paypal for both domestic and international.
