Multimeter Safety Tips and Precautions

Multimeter Safety Tips and Precautions

Multimeters are widely used to measure Current, Voltage, and Resistance and as technology progresses more features and measurements are being added to Multimeters for easy use in a single compact device.

Digital Multimeters or Analog Multimeters both are very important for Electricians as they use it to diagnose faults as this can be a risky task, so this requires to be safe and use precautions before getting ourselves into serious trouble.

multimeter safety precautions

Here is a list of thing to do.

  1. Before testing electrical equipment be sure to check the Multimeter to see if there is any physical damage to the device. Check the accessories, cords, cracks, and breakages because working with electrical wiring and currents can be a huge risk as it can be fatal if not dealt properly.
  2. Be sure to understand what you want to measure and how to measure it properly to avoid using multimeter the wrong way.
  3. Make sure the Multimeter you are using is of good quality and has been tested before for safe use.
  4. Check the Probe for any faults or damages. Do not touch the probe Tips with one another when they are still connected on the electrical circuit and after using the Multimeter carefully put the multimeter and all of its accessories in a safety box to avoid potential damage in any case.
  5. When using the multimeter try to use Gloves to avoid accidental electric shock.
  6. Be specific on what you want to test and what Multimeter will be suitable. Multimeter certification and standards are divided into categories from CAT 1 to CAT 4 depending upon the Danger level, protection level, and electrical environments. The more close you are to the power source the more the CAT level and the higher the CAT level the more resistance is in the multimeter for protection.
  • CAT 1 devices are used for minimal out voltage such as Low level and limited electrical equipment.
  • CAT 2 is used for Appliances and household products such as Refrigerators,
  • CAT 3 is Mostly used in commercial equipment, fixed electrical panels, bus and feeders in Industries, motors, etc.
  • CAT 4 is used to check the outside wire coming directly from poles to meters and distribution panels or primary current protection equipment.

So be very careful while testing equipment according to the CAT level as a Lightening strike or any electrical spike could potentially harm you. The greater the short circuit current the greater the CAT category must be used and if you are buying a digital multimeter or an analog multimeter keep these CAT ratings in mind as well as what are you going to use it for.
