The Gardner Bender Multimeter Tester GMT-319 is designed for electricians and DIY enthusiasts who need a reliable tool for basic electrical measurements. Its key benefit is the clear, analog display with a mirrored and color-coded scale for easy reading of 19 ranges and 7 functions, including an audible continuity tester. A potential caveat is its manual range selection, which requires user input for setting the correct measurement range.

The mirrored scale on the analog display is designed to reduce parallax error, allowing for more accurate readings by ensuring the user's line of sight is directly perpendicular to the needle.
Refer to the product's operating instructions or electrical testing guides to determine the expected voltage, current, or resistance of the circuit you are testing. Then, turn the 20-position rotary dial to the corresponding range on the multimeter.
Yes, the Gardner Bender GMT-319 can be used for many basic automotive electrical tests, such as checking battery voltage or continuity of circuits, provided the ranges and functions are appropriate for the automotive system.
An audible continuity tester is a feature that beeps when a complete electrical path (low resistance) is detected between the test leads, indicating that two points are connected.
Always select the correct range before taking a measurement. Avoid exceeding the maximum voltage or current ratings. Utilize the fuse overload protection by ensuring it is functional. Keep the meter clean and dry.
Yes, the GMT-319 comes with replaceable test leads, allowing you to easily swap them out if they become worn or damaged.
Analog multimeters use a needle to display readings on a scale, which can be better for observing trends. Digital multimeters display numerical values, often offering higher precision and auto-ranging capabilities.
Verify test leads are securely connected to the meter and the circuit. Ensure the correct function and range are selected. Check the fuse and replace if blown.
Confirm the dial is set to the continuity function. Check that the test leads are making good contact with a conductive path. Ensure the leads themselves are not damaged.
Ensure the correct range is selected for the measurement. Check for loose connections at the test points. Verify test leads are not damaged. For analog meters, ensure you are reading perpendicular to the scale to avoid parallax error.
Check and replace the battery if the unit uses one. Ensure the battery is installed correctly.
