Choosing the proper meter and leads are very important to the success and safety of the HVACR technician. Always choose a meter that has the highest category rating that you can afford. This is preferably a CAT 4, 600v rating. Make sure that the test leads carry the same for your personal safety.
For more of this information on choosing the proper test equipment, obtain the series of the Technical Institute Manuals, available at the ONLINE STORE at RSES.
