Overview
The FR MT40 is a versatile and compact digital multimeter designed for troubleshooting electrical problems in automotive, domestic, and industrial applications. It is the go-to choice for engineering students and DIY makers because it covers all the “bread and butter” measurements: Voltage, Current, and Resistance. Unlike basic entry-level meters, the MT40 includes a loud continuity buzzer (crucial for finding short circuits) and a backlight, so you can work in dimly lit corners of your project or engine bay.
Key Features
Large Backlit LCD: Easy-to-read 3.5-digit display with a bright backlight for nighttime or dark workspace use.
Continuity Buzzer: Instantly identifies short circuits and broken wires with an audible “beep.”
Data Hold Function: Freeze the reading on the screen so you can record it without losing the measurement.
Rugged Protection: Comes with a thick, removable yellow rubber holster that protects the meter from drops and bumps.
Integrated Kickstand: Built-in stand for hands-free operation on your workbench.

Why choose FR MT40 over generic meters?
The “Buzzer” Factor: Many cheap meters don’t have a continuity beep. The MT40 does, which saves hours of troubleshooting.
Safety: Features internal fuses to protect the meter and the user from accidental over-current.
Build Quality: The test leads are thicker and the selector switch feels “clicky” and secure, not mushy.
