KAAYEE Ohm Resistance Meter 10Ω OLED Four-wire Digital Micro-ohm Milliohm Tester

الوصف

Ultra-low test current, effectively prevent the measured resistance temperature drift caused erratic readings Built-in polymer battery, MicroUSB rechargeable design, no external power supply A key to zero, auto range, no need to open the cover to calibrate Precision ADC precision reference resistor + LED dot matrix display, AVR microcontroller Automatically shut down when not in use, if the measurement automatically maintain power Typical applications: Measuring electrical resistance between chip rectifier Measuring electric brush bit Motor winding resistance measurements Survey vessel, vehicle, aircraft and other metal riveted resistance Measure the contact resistance of the circuit breaker Measure the resistance of the ground wire welding points Bolted wire contact resistance measurements Transformer winding resistance measurements Ground wire resistance measurement Grounding wire resistance measurement line Measuring inductance coil resistance MOS on-resistance measurement Measuring trace current sampling resistor Test lead resistance: a large current model mobile power Han, well aware of how much wear and tear Maintenance of high-power motor generator winding resistance Check the metal rivet firm level Measurement of high-power MOS-resistance: only then with a 4.5V or 10V power supply to provide gate voltage, true and false judgments immediately mos Measuring range: 10Ω Measurement error: ± (0.5% reading + 5 digits) Resolution: 1μΩ Test current :0-100mA Test voltage :0-3 .5 V Dimensions: 85 * 50 * 21mm Reading cycle: about 1 per second Continuous use of time: more than 15 hours
