DTA Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode
This article has also been viewedtimes. You can now compare your readings to the schematics. For example, in most occasions, resistance can be measured without the unit to be powered. No data is shared with Paypal unless you engage with this feature.
You can use a multimeter across the two poles to see if there is continuity. No data is shared unless you engage with this feature.
Include your email address to get a message when this question is answered. Turn the power on. Place the red probe on the positive side of the diode and the black probe on the negative side. Observe polarity when measuring DC voltage or millivoltage.
Let’s take for example a simple, 2 pin resistor: Hlw the multimeter to measure current. If you get a reading of less than digitall but more than mulfimeter, the forward bias is good. Call an electrician if you don’t know what you are doing. Multimefer software libraries such as jQuery are loaded at endpoints on the googleapis.
The current will run through the circuit, up the red probe and through the multimeter, then out the black probe and into the circuit. Some articles have Vimeo videos embedded in them.
If you are measuring a voltage of 22 V at the 20 V selection, the meter would either show “1” or some kind of indication for over-range. A reading of “OL” or 0 while testing forward bias, and 0 while testing reverse bias indicates that the diode is bad.
In its various positions, each kind of measurement is divided into many maximum values; for example, the resistance measurement area would include 5 different positions, one for Ohms, mhltimeter for 2 Kilo-Ohms, one for 20 KOhms, one for KOhms and one for 2 MOhms. This is a dangerous situation which could burn your house down if there is no earth leakage system in your house.
This allows for easy troubleshooting of damaged parts or for identifying the characteristics of an unknown part. Check the reading of your multimeter. Every single thing in the world has a resistance, be it zero, small, high or infinite.
DT9205A Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode
You can use the touch-hold feature if desired. Already answered Not a question Bad question Other. If you’re unsure of the current, start in the 10 amp terminal until you’re sure the current is less than milliamps.

In general, if the knob’s indicator shows towards DCV 20 V, then the user will measure the direct current voltage of a circuit which is less than 20 V. Plug the black cable on COM and the red cable on V socket of the multimeter.
Place the leads on either side of the section of circuit you’re testing. You can use this to streamline signing up for, or signing in to your Hubpages account. Twist the selector knob to set the multimeter to measure resistance.
