Turn the power on. Switch the rotating knob to the resistance area and choose the 2 KOhm position. This is used to collect data on traffic to articles and other pages on our site.

In some measurements, muktimeter do not have to keep the device to be checked ON and running.

This is a cloud services platform that we used to host our service. Let’s take for example a simple, 2 pin resistor: Help answer questions Learn more.

How do I use a code reader to trouble shoot an 87 Ford4 wheel drive ? Observe polarity when measuring DC voltage or millivoltage. Let’s see how it would be with a car battery: Resistance is a sign of how much a connection “resists” to the electron flow, which essentially means the current.

To provide a better website experience, turbofuture. As far as AC is concerned, the measurement does not differ from the previous method.

DT9205A Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode

This is a dangerous situation which could burn your house down if there is no earth leakage system in your house. Multijeter you get a reading of less than 1 but more than 0, the forward bias is good.

Keep the cables connected as before, switch the rotating knob to ACV or AC Voltage, choose the appropriate value position and touch the one end on the phase and the other on the neutral or ground slot in your wall socket. By using this service, some information may be shared with YouTube. Not Helpful 3 Helpful 8. This makes the process much easier for the hobbyist but hoq professional engineer hwo well. Voltage is the electrical potential difference dgital two points and its unit is Volt V. To check the voltage between two spots, follow the next steps:.


A multimeter with such feature can identify the magnitude of the measurement and will range directly to the appropriate level of value, something which eliminates the need of many different knob positions for the same kind multimeger measurement. If you are not knowledgeable at all about electricity, you should rather start learning some basic electronics theory: Put the black probe in the common terminal and the red probe in the terminal marked for measuring volts and ohms.

The surface of the front side has text which shows what is to be measured at each position of the knob. Some also test diodes and continuity. If you’re unsure of the current, start in the 10 amp terminal until you’re sure the current is less than milliamps. Integrated circuits cannot be tested with continuity unless you are familiar with the pin assignments, i. If you’re measuring DC voltage or millivoltage, you’ll need to place the black probe on the negative side of the component and the red probe on the positive side.

Insert the black probe into the common terminal and the red probe into the terminal marked for measuring volts and ohms. An electronic multimeter is the very first instrument an multieter engineer will have to buy, even before buying soldering tools multimdter as iron, solder, and howw.

In the diagram, you can dt9205 voltage measurements during normal operation. How can I know if a particular device is functional or faulty? You can now compare your readings to the schematics.

Please choose which areas of our service you consent to our doing so.

Also, test continuity between live and earth to see if there is a possible short circuit. To use a digital multimeter to measure voltage, start by putting the black probe in the common terminal and the red probe in the terminal that’s marked for measuring volts. Any voltage reading which does not coincide with the schematics will tell you that something is wrong with the circuit where the I.


Rotate the knob to 20 V position at the DC voltage area. It depends on the type of switch. This is used to provide traffic data and reports to the authors of articles on the HubPages Service.

Most DMMs include tiny little slots where the pins of the legs of a transistor or diode can be inserted – if the appropriate choice has been made through the rotating knob for example, pointing at transistor checkthen the screen will show relative information about the part under check.

Not Helpful 1 Helpful 2. Other possible sockets are temperature sockets, in which a 2-prong thermocouple with the ability to measure temperatures at its end can be plugged. If you leave the resistor in the circuit you may not get an accurate reading.

This will be noted later too, at the stage where you will be trying to measure AC voltage or current.

Put the black lead of a multimeter to one end of your fuse and the dt9205 lead to the other end of the fuse. On the other hand, current can easily move through water, because water has almost zero resistance to it. Some articles have YouTube videos embedded in them. Place the probes on either side of the break, observing polarity black probe on negative side, red probe on positive side.

To create this article, 18 people, some anonymous, worked to edit and improve it over time. Once you are sure that there is no power, remove the resistor you want to measure.
