Can you direct the direct current with the pliers jaw (not measuring pen)?
- Fluke 317/319 clamp tableDC range 40 A, 600 AResolution 0.01 A, 0.1 AThe accuracy is 1.6% + 6 words (40 A)1.5% + 5 words (600 A)s
How does the multimeter measure Ann?
- AC current clamp type meter, direct measuring or current transformer.DC high current; you can design a "shunt", that is, the design of a shunt circuit, take the voltage samples on the resistance, and then calculate the circuit current.s
What is the cause of the tripping of the two phase motor?
- Leakage of electricity, turn on the motor - coil some varnish, and then dry, will solve the problem. If you do not have this process, let the maintenance master help you solve.s
What's the caliper watch for?
- Measuring alternating current, the range is very large, generally can be measured thousands of ANN current, and the principle of the same current transformer. It also has the auxiliary functions of measuring voltage and resistance.s
How to distinguish stealing from electricity
- 1, carefully check the internal wiring of this new watch, whether or not the connection is off or short circuited.2, check the line of the meter to see if the user has other circuitry to bypass the meter.3, check the line, we must ensure that the entire line intact, there is no "private", "random" phenomenon.s
How to maintain and maintain the communication and power room?
- 1, multimeter. As one of the necessary testing tools in the daily maintenance, the multimeter is mainly used for testing voltage, current, frequency and other related parameters, requiring the resolution of at least 41/2 bits (10000 words). At present, the maintenance personnel is usually used by the American FLUKE company F80, F180 series of high precision digital multimeter, the multimeter resolution can reach 44/5 (50000 words), can fully meet the "Regulations" on the accuracy of the measurement requirements. At the same time, this kind of multimeter with anti dropping, anti burning, antimagnetic, anti sputtering, intelligent alarm and good maintenance, very suitable for field use.s
How to accurately measure the Ma level current
- Try a Fluke 77X Ma level process caliper table. Simple and clear.If you are going to elaborate on the principles and processes, that's a thesis.s
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.s
