What is basic test equipment?

Test instruments or meters are the most common pieces of electrical equipment that measure these values. Voltmeters are used to measure voltage;ammetersare used to measure current; ohmmeters are used to measure resistance; and watt meters are used to measure power.

Why do we need to test equipment?

Testing helps identify the components that undergo timely degradation due to the device's exposure to external disturbances such as heat, shocks, vibrations and fluctuating environmental conditions. This analysis further helps predict equipment failure and perform calibration before any considerable damage.
