Definition: Any closed circuit consists of three components voltage, electric current and resistance. Of these, the voltage is measured in the voltage, in the Ampere and in the Ohm. Of course, if you want to test the pressure, flow and current in a circle, you will need several different ranges of different types and capacities.
However, in practice, different types of readings are carried out using a single measuring device. This tool is also known as Multimeter. There are various types of multimeters available in the market and the PAN model of the SANWA company is particularly popular. There are several scales available in this meter to measure the resistance, DC flow, DC and AC pressure using this meter.
In this meter, to calculate resistance,DC current,DC or AC voltage.
1. First of all make sure that any pressure or flow is to be calculated. Also, estimate the general proportion.
2. If measuring pressure or flow, if its quantity is not estimated, then it should always be calculated from high range to low range. E.g. If calculating DC voltage is not shown using the first 1000v range, then accurate reading should be obtained using the descending range such as 500V, 250V, 50V or 10V respectively, while using low range without any prediction, the meter will be burned.
3. When measuring the resistance or voltage, the meter connected in Parallel, but for measuring the current, the meter is connected in series.
It is necessary to have at least 80% of the electrical supply while checking the electronic device, but it is necessary to turn off this supply while calculating the opposition. If the measurement of the opposition is not closed, then the device should not be able to touch the proof of the master, not measure any of the other miracles of the meter, and then measure the plumb one of the opposite positions of the suspected position.
