Analog multimeter is also called analog multitester due to test the electrical instruments to measure the current, frequency, voltage, resistance, and the signals power. Analog multitester has a needle with the scale. Analog multimeters with the switch range are cheap, but the beginner users find difficult to read the measurement accurately, especially, for the resistance. There are many types of analog multitesters are available in the market and every type has its advantages and disadvantages. The digital multimeter is better due to its high resistance as 1M to 10M against the analog multimeter for the same range to use as voltmeter. Otherwise, analog multitester is better due to its display for looking to the voltage, which moves slowly.
Basically, the analog meter is used to measures the electrical potential in volts, current in amps, and resistance in ohms. Analog multimeter used to test the electric short-circuits and electronic problems. Analog meters are best for the measuring of AC current, DC current, frequency range for the AC currents, DC voltage, AC voltage and the decibel measurements. Many new analog multitester comes with the advanced features of IC, Diode, capacitors testing. It is important to check for the measurement range for a specific value, before purchasing the analog multitester. Analog meters are normally small in size to keep in hand or little big to put on a table to test of the different devices as a mobile technician.
The entire analog multimeter shows the result with the movement of a needle around the printed scale of many types on top. Analog meters have many keys to select the functions due to need manually. You must have knowledge to operate and read the measurements, some time you need to multiply the reading to check the final value. There are many analog multitesters in the market with different facilities such as hang on wall, come with stand in order to hand free work. Many of the analog meters come with the necessary parts, but you can buy the extra parts to facilitate your job such as jumper wires and alligator clips. Alligator clips hold firmly the wires or the contacts to get the hands free and accurate readings while on job. The most common features of the analog multitester are such as overload protection, mirrored scale, diode testing, temperature compensated, and the battery test. Many devices come with batteries and can be operated without plug in power.
The entire analog multitester comes with the overload protection having a fuse to protect the meter from damage. Temperature sensitive appliances come with the programming or the electric components made to counteract the common errors due to the temperature changes. The analog multitester can easily read the instrument as to provide accuracy with the help of mirrored scale to avoid the parallax errors. You can adjust the range switch to select the desired range to measure the appropriate unit in the analog multimeter. There is a diode testing methods to test the device with the diode problem. The operating temperature is an important environmental parameter to observe before purchasing any analog multitester.
Finally, you can buy these analog multitesters from any big electric store for a price range from $15 to $5000 according to the functions are provided on the analog multimeter due to the importance of your work type and technical needs.
