Microhmmeter Microhmmeter index microhmmeter Microhmmeter Microhmmeter action (DC resistance rapid tester) Model: OMT2A a. Overview OMT2A DC resistance tester (Microhmmeter) is to replace the DC single, high-precision arms bridge replacement. The instrument uses an advanced switching power supply technology, the four and a half LCD display measurement results, three semi-LCD display ambient temperature or test current value, to overcome the shortcomings of other similar products from the LED displays the value of reading in the sun inconvenient, while the ability to automatically arc function. This instrument has a fast speed, high precision, intuitive display, anti-interference capability, small size, low power consumption, stable and reliable test data, without human factors and so on. Is a measure of power transformers and other inductive load resistance and low pressure switch contact resistance, cable or connector resistance weld the ideal instrument, the measurement bridge faster than a hundred times. Instrument built-in rechargeable battery pack (12V), AC, DC, easy on-site and field testing. II. The working principle of the instrument has a DC current to produce a constant current source. When measuring resistance, constant current from I +, I- terminal to be fed into the sample constant, the current value of the corresponding voltage generated in the test object, the voltage value at V +, V- terminal to retrieve the machine, After amplification, the direct use of four and a half LCD digital display of the resistance value of the test product. III. Features 1, rechargeable battery pack included field testing without AC power, easy to use. 2, the output charge current up to 2A, the test speed. 3, the resistance measurement range is 1μΩ ~ 2KΩ, wide range. 4, the use of imported high-quality components, software design multiple interference procedures, measurement accuracy and good reproducibility. 5, a liquid crystal display, adapt to different working environment. Four. Specifications 1, the use of conditions: Ambient temperature: 0 ℃ ~ 40 ℃ Relative humidity: ≤85% RH 2, measuring range: 1mΩ ~ 20mΩ; 20 ~ 200mΩ; 0.2 ~ 2Ω; 2 ~ 20Ω; 20 ~ 200Ω; 200Ω ~ 2kΩ . 3, measurement accuracy: 0.2 4, Resolution: 1μΩ 5, the constant current source: 2A (1uΩ ~ 2Ω); 0.2A (2Ω ~ 200Ω); 0.02A (20Ω ~ 2000Ω). 6, the working voltage of the DC 11V ~ 14V; AC 220V. 7, power consumption: ≤15W 8, Dimensions: 335 × 275 × 175mm Weight: 2.8kg Microhmmeter, DC resistance tester, DC resistance rapid tester selection Description: a constant current source 1A (Model: OMT1A); constant current source 2A (Model: OMT2A); constant current source 3A (Model: OMT3A).
