Precautions of multimeter

Some precautions of multimeter:

• When you have to use multimeter first check proper DC polarity when measuring DC.
• You have to always start with the highest voltage or current range.
• De-energize and discharge the circuit completely prior to connecting or disconnecting to a device called a multimeter.
• Be sure that the multimeter is switched during the to AC prior to trying to measure AC circuits.
• Choose the final range that enables a reading close to the middle of the scale.
• Set the ideal current range before measuring higher current or some else it will blow the digital multimeter fuse. 
• A resistor should be measured standalone or the connected parts in the circuit may affect to some of the reading.
• Never apply power to the circuit when you have to measure resistance with a multimeter.
• Be sure to read AC measurements on the AC voltage position.
• In case you want to verify the presence of dangerous voltage in a circuit with a digital multimeter, it is crucial to verify both the  AC as well as DC voltage.
• Make sure that change the 0 ohms reading after changing resistance ranges before creating a resistance measurement.

Applications of multimeter

We all know that a multimeter is extremely too important for electronics and electrical instruments and is extensively used for carrying out various tests and to measurements in electronics as well as electrical circuits. 

There are two types of multimeter basically analog multimeter and digital multimeter. they are many advantages of the analog multimeter as well as digital multimeters advantages. The applications are measuring accurately circuit and component parameters. They are different type of multimeter is used for the test, to adjust and troubleshoot electronic circuits, traditionally multimeter of either type measure three main parameters.

1. Current both AC and DC

2. Voltage both AC and DC

3. Resistance

The main Applications of multimeter are listed below:

• Voltage measurement: High and low value DC measurement and peak to peak and DC average measurement.
• It will use for temperature and environmental applications: Low-cost weather station, DMM internal temperature.
• Resistance measurement: Micro ohm meter, measuring with constant voltage and measuring resistance with constant current
• Time and frequency measurement: Fast frequency, and time measurement
• Current measurement: DC current measurement, true RMS AC current
