A multimeter is a fundamental apparatus for any individual who does anything utilizing hardware. Inside this guide we will share all the intricate details of utilizing a multimeter and you can likewise extend see specialized data about how the readings are taken. DC Voltage is one of the most widely recognized employments of a multimeter. This is utilized for anything from checking the voltage at a specific piece of a circuit to testing a battery. DC Voltage is shown a couple of various ways on multimeters yet for the most part either VDC or DCV is utilized.
Choosing a scale – The scale that you select will peruse up to the expressed voltage a size of 20V would peruse from – 20V to 20V. Most multimeters give you a selection of scales which you can utilize. A normal multimeter may contain the accompanying scales 200m, 2000m, 20, 200 and 1000. The scale that you decide for your perusing should cover the voltage run that you are utilizing yet the lower scales will give you a more elevated level of exactness. For instance on the off chance that you were trying a 1.5V AA battery you would be best utilizing the 2000m scale. This scale will peruse in mV mill volts so 1.5V would be shown as 1500. This scale will show a limit of 2000 which would be 2V. On the off chance that anyway you were trying a 9V PP3 battery you would need to utilize a higher scale. The 20 scale which would peruse up to 20V would be the scale to utilize. Extremity – The extremity is not generally the best issue with DC Voltage as though you get the test drives the incorrect path round all that will happen is that the screen will show a short image and the voltage.
Opposition is an extremely helpful capacity of a dong ho van nang for large number reasons. We regularly utilize a multimeter on the obstruction scale to check the estimation of a resistor or as a simple technique for checking congruity some multimeters have a progression work. Choosing a scale – The scale that you select for the obstruction will affect the precision of your readings. The scales will peruse from 0ohms to the estimation of the scale that you have chosen. You should plan to utilize a scale where the normal obstruction is between the scale underneath and the scale esteem.
Range – Use for resistors between
- 200ohm – 0-200ohm
- 2000ohm – 200ohm to 2000ohm
- 20k – 2k to 20k
- 200k – 20k to 200k
- 2000k – 200k to 2000k
Air conditioning Voltage is the estimation scale that you would utilize in the event that you are trying mains electrical gear and supplies.
