Product Description

This multifunctional analog multimeter was designed for the homeowner, hobbyist, or professional needing to make electrical and electronic equipment measurements. Capable of measuring 6 functions on 14 ranges on it's easy-to-read color-coded analog display you'll find yourself reaching for this handy unit almost every time. Unit tests AC and DC voltage, DC Current of Resistance, and common household batteries from 1.5V thru 9V. Unit includes built-in Zero Ohms adjustment dial allowing you to reset prior to resistance testing and to perform internal battery test function. Unit incorporates fuse overload protection circuitry to protect the user and a mirror scale is provided to reduce the possibility of parallax errors. Common measurements with this unit include: testing household batteries for charge level, troubleshooting various low voltage circuits, testing wall receptacles for proper voltage and grounding, and troubleshooting electrical cords, strings of lights, fuses, and switches to determine if they are operating properly or if a break in the circuit exists and the item in question needs to be repaired or replaced. The decibel feature of this multimeter is used for transistor gain measurement in electronic circuits and should not be confused with audio decibels. If you are looking for an all-around electrical tester you've found an excellent choice.

This is a great tester for home maintenance. I like the fact that it uses a regular meter instead of a digital display. It is a great compact analog Volt/Ohm/Amp meter.

This Gardner Bender GMT-318 Analog Multimeter, 6 Function, 14 Range, AC / DC Volt, 500V testing meter is the type I have always used to build and test motor circuits and lead wires in mineral processing operations. This meter works perfect replacing one of my older and cracked meters and to me- the analogue type of function is much better than 50 different settings on digital meters. Very well- made and functions perfectly and is exactly the right size for me. Excellent find at a good price.

Extreme difficulty inserting the AA cell. It required plastic meltology to clear plastic lands near the battery contacts before it would accept the battery So far it's a usable meter.

The finish and easy to read gauge was real nice , HOWEVER ,it was totally non-functioning. The battery compartment( a battery was needed ) was too short. The standard AA battery is 1.908". the compartment was 1.863". That is .045" or 1.14mm to short to allow battery installation. This prevented its use. A very POOR example of a Plastic injected port . And a Great Example of Terrible Quality control

About The Details
Reviewed in the United States on August 24, 2023
Sometimes it is handy to load down a circuit with a meter rather than adding a resistor, such as when checking voltage on a floating wire running past other wires which can measure 90VAC with a high impedance meter. Unfortunately, the battery holder is sized too short, so the battery has to be forced into the holder. Perhaps in China AA batteries are shorter. It doesn't matter. Otherwise, it seems OK. Normally I use a Fluke True RMS meter. I have no way of measuring accuracy other than to compare meters. The resistance zero on the left side worked. For now, it will be a good garage meter.

The female test lead ports on this meter are smaller than the standard test leads found on any other meter and they are low quality. Good for hobbyists not suitable for field work.

Gone are the days when you could buy a high-quality, low-price Micronta (Radio Shack of yoore) analog VOM.In line with general dumbing-down in our society, analog meters were long ago replaced by digital. Digital meters are the stupidest idea since the Edsel. They work only if the voltage is steady unless they feature filtering in which case the response is slow. And you still get unsteady readings. On top of that, digital meters are subject to aliasing error. Never mind what that means, it can be a disaster if there is noise on top of dc voltages you're tryhing to measure.So today your choice is a $400, 30-year-old, used, beat-up, in doubtful condition Simpson or a new cheapie like this one. (I noticed practically none of the former offered on amazon even promise operability!)I recently bought a similar-looking cheapie which however was vastly inferior to this one. Interior had jury-rigged wiring like some grade-school kid had wired it up; revealing the need for ad-hoc rewiring of an incomplete design, easily recognizable by an electrical engineer such as I. It sure enough crapped out in no time.This unit has no such garbage hookups, is fused, a really nice thing to have, and the battery compartment lid fits so snugly you really don't need the mounting screw.Some advice:1. the instruction manual (on-line) says "ALWAYS REMEMBER THATCONTINUITY CHECKS ARE TO BE MADEWITH THE POWER TO THE CIRCUIT ". Be sure to do just the opposite! Kind of obvious.2. Comes without an AA battery. Actually, wisely so. Saves on shipping cost and potential ravages caused by a leaking battery.3. I will be ordering spare fuses for those inevitable screw-ups like trying to measure resistance across a 250-volt line.Other than that, a happy acquisition without even a dent in my pocketbook. Go for it.
