Which device is NOT listed as a programming device for configuring VFDs?

• A. Drive-mounted programming interface
• B. Handheld programmer
• C. External laptop computer
• D. Multimeter

Answer: (D)

Configuring VFDs requires tools that can communicate with the drive and write parameter settings. A drive-mounted programming interface lets you change settings directly on the device, a handheld programmer provides a portable way to enter parameters near the drive, and an external laptop computer with the vendor’s software enables more advanced or bulk configuration. A multimeter, by contrast, is a measurement tool used to verify voltages, currents, and resistance. It doesn’t have the capability to program or configure the drive’s parameters, so it isn’t listed as a programming device. It’s useful for installation and troubleshooting checks, but not for configuring VFDs.
