Who can specifically describe the automatic conversion range function, and some automatic?
Diode test: shows the forward conduction voltage of an approximate diode. Used to measure the transistor characteristics of diodes and transistors. Diode measurements: test current digital multimeter resistance profile provided is very small, in the positive resistance measuring diode, transistors and other nonlinear components, several times higher than even a few times measuring pointer multimeter resistance profile values, this is a normal phenomenon. It is recommended to use the digital diode meter of diode meter to measure the positive and reverse voltage drop of diode PN junction to judge the unidirectional conductivity of diode.
Maximum / minimum: the maximum / minimum value per unit time of an operation. Such as the rate of 3 seconds / times. The maximum value is the maximum value within 3 seconds.
On pass test: on line test means that when the resistance of the line under test is lower than that of the buzzer, the buzzer will alarm. The utility model has the advantages of an operator does not need to observe the display of LCD value, just stare at the measured line and pen, voice alone can judge the on-off circuit. Not only the operation is simple, but also can greatly shorten the detection time, improve work efficiency!
