China Wholesale Nonlinear Circuit Chaotic Pricelist – LEEM-11 Measurement of V-I Characteristics of Nonlinear Components – Labor
China Wholesale Nonlinear Circuit Chaotic Pricelist – LEEM-11 Measurement of V-I Characteristics of Nonlinear Components – Labor Detail:
Traditional digital voltmeters generally have an internal resistance of only 10MΩ, which introduces a large error when measuring high resistance components. The tester innovatively uses ultra-high internal resistance voltmeter which is much larger than 1000MΩ, greatly reducing the system error. For conventional resistors less than 1MΩ, the system error caused by the internal resistance of the voltmeter can be ignored, regardless of the voltmeter internal and external; for high resistance, phototube and other components greater than 1MΩ can also be measured accurately. Thus, the traditional basic experiments to expand the content of new experiments.
Main experimental content
1, ordinary resistor voltammetric characteristics measurement; diode and voltage regulator diode voltammetric characteristics curve measurement.
2, volt-ampere characteristics measurement of light-emitting diodes, tungsten bulbs.
3, innovative experiments: measurement of volt-ampere characteristics of high resistance and capacitance.
4、Exploration experiment: the study of the influence of the internal resistance of the meter on the measurement of volt-ampere characteristics.
Main technical parameters
1, by the regulated power supply, variable resistor, ammeter, high-resistance voltmeter and components under test, etc.
2, DC regulated power supply: 0 ~ 15V, 0.2A, divided into two grades of coarse and fine tuning, can be continuously adjusted.
3, ultra-high internal resistance voltmeter : four and a half digit display, range 2V, 20V, equivalent input impedance > 1000MΩ, resolution: 0.1mV, 1mV; 4 additional ranges: internal resistance 1 MΩ, 10MΩ.
4, ammeter: four and a half digit display meter head, four ranges 0 ~ 200μA, 0 ~ 2mA, 0 ~ 20mA, 0 ~ 200mA, internal resistance, respectively.
0 ~ 200mA, internal resistance of: 1kΩ, 100Ω, 10Ω, 1Ω, respectively.
5, variable resistance box: 0 ~ 11200Ω, with a perfect current-limiting protection circuit, will not burn out the components.
6, the measured components: resistors, diodes, voltage regulators, light-emitting diodes, small light bulbs, etc.
