The multimeter is a great tool for any technician who needs to test and diagnose electrical systems.

These handy devices combine multiple functions into one portable unit. Technicians can use this tool for a variety of applications, including voltage drop, continuity checks, diode checks, capacity checks, and more.

Before technicians use a multimeter, there are several pre-checks they should run through first. These include checking the leads and making sure the amp fuses are good. In the video above, Purkeys National Truck & Fleet Sales Representative, Larry Rambeaux, demonstrates how to properly pre-check a multimeter.

Performing the right pre-checks is important, because all service manuals and technical bulletins are based off of two presumptions: that a technician knows how to use a multimeter and that the multimeter is in proper working order.

When a multimeter is not calibrated correctly, has bad leads, or is not on the right setting, technicians can waste a lot of time or misdiagnose important issues. Ensuring the proper use of a multimeter with the right pre-checks can help a fleet save time and money.
