Purkeys’ new product, the Multimeter Training Unit (MTU), helps fleets train technicians on a heavy-duty vehicle’s electrical system. The MTU allows technicians to practice their skills with a multimeter in a controlled environment before testing on a vehicle.

Purkeys Chief Engineer Dale Henningson said one of the main benefits of using the MTU is the unit’s portability and ease of use. The MTU allows technicians to practice at home or at a desk instead of tying up a truck for training purposes. This training unit also allows technicians to easily test different variables to see how they are measured by a multimeter.

“If a technician goes out and measures a battery, they’re going to get one reading,” Dale said. “With the board, they can experiment with different states of charge and see how they correspond on a multimeter.” The ability to change what is being measured makes it easier for technicians to fully understand the numbers and how they relate to a vehicle’s electrical system.

With the MTU, not only can a technician vary individual aspects such as state of charge, they can also easily change the component that is being measured. The MTU has various sections including battery, alternator and pulse width modulator simulation. Each of these different areas correspond to functions on a multimeter. This allows technicians to practice with every function and to test situations that could not be easily produced on a vehicle.

Understanding how to use a multimeter is essential for diagnosing and repairing electrical systems and components within a truck. According to Dale, “When you’re dealing with electrical circuits, you can’t necessarily see what’s going on. You can’t look at a battery and see if it’s charged or not. Multimeters can measure these values and help us understand what’s going on with the electrical system.” When technicians are properly trained on how to use a multimeter they can quickly diagnose and repair electrical problems. This allows fleets to save time and money by minimizing down time.
