How to use an Analog Multimeter
…it’s simpler than you think!
Multimeters are inexpensive and easy to operate, making them very popular. They are very commonly used as devices for electronics circuits testing. Multimeters are categorized into two different types – analog and digital. While the internal circuitry and operation of both are very different, their usage is more or less similar.
Analog multimeters have been in use for a long time and are very flexible in their operation. An analog multimeter can be used for testing a number of electronic components and parameters such as resistance, voltage, current, to name a few.
If you are using an analog multimeter, the first step is to switch the multimeter on. Next, the probes (or the leads) need to be inserted in to their correct positions. There can be a number of connections that can be made, and depending upon what is to be connected, the right positions should be determined. Care should be taken to not insert the leads in to a low current position, if high current is to be measured.
Next step is to set the center switch or knob to the required measurement type and the proper range. The range selected should be higher than the anticipated value. If the value is not known then the multimeter should be set to maximum and the range accordingly decreased afterwards. This ensures that the meter does not get overloaded. The range should be optimized for getting the best reading possible.
Once the reading has been taken, it is good practice to place the multimeter probes in to the voltage measurements sockets with the range set to maximum voltage. This ensures that even if the multimeter is accidentally connected, there is no damage to the multimeter or other electronic components of the circuit. Or if the reading is complete, then the multimeter can be switched off.
