Variable speed measurement


The Extech MN62 is optimized for electrical installations and repairs in residential or commercial wiring, HVAC/R work, and plant maintenance. It delivers full-size DMM capabilities such as True RMS accuracy and a low pass filter mode to manage noisy signals. On HVAC/R equipment or at manufacturing plant sites, where equipment like motors, pumps and blowers are regulated by variable frequency controls or drives, a low pass filter can be activated to reduce high‐frequency noise that can result in inaccurate measurements.
