Product Description

Style: 3145

The Triplett 60 Ruggedized Volt-Ohm Milliammeter is a manual-ranging meter and has 28 ranges for measuring AC/DC voltage to 1,000V, DC current to 1,000mA, resistance to 10 megaohms, and decibel ranges from -20dB to +62dB. It employs three-fuse overload protection to prevent damage and keep the user safe with 1/8 and 1 Amp fuses for normal overload conditions (spares for each included) and a 2-amp fuse for high energy fault currents. The meter has a polarity-reversing switch, a mirrored scale to reduce parallax error, and confidence check to test batteries, fuses, leads, and meter accuracy. The meter comes in an orange case that helps protect it from 5' drops and rough handling. The meter measures 3-1/4 x 5 ¼ x 7 ¼ inches (H x W x D) and weighs 2 ½ lb. (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.)

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltage. Safety ratings are based on International Electrotechnical Commission (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.

Triplett manufactures test equipment for electricians, home security installers, and telecommunications technicians. The company, founded in 1904, is headquartered in Manchester, NH.

The Triplett 310 has for over 50 years been a good choice for those that need a compact analog VOM. The current model (type 7) uses a readily available (and cheap) 12 volt battery for the highest resistance measurement range, rather than the hard to find (and expensive) 15 volt battery used by previous versions of this meter. (see my review for the 15v battery)

Actually, this meter will (unlike a digital multimeter) make most measurements with no battery at all, batteries are only needed for the resistance ranges. (and they ARE included)

This is a well made, high quality meter!

The cats meow for a small, carry anywhere, always have it with you meter. I have a half a dozen top DMMs but sometimes you need an analog. Older units have EXPENSIVE batteries. Here's the solution to that:

310-5 VOM Battery requirements (2 different types)

1.5V "N" battery Available everywhere. Inexpensive - 8/2013 ≈$1.25
15V Battery Everyready 504 ZnC (L-15.1mm x H-49.9mm x W-15.9mm). Eveready hard to find and $$$. Replacement - Excell M504 ≈$11 still too expensive. Roll your own; works very well.

15V 504 replacement - "Button"cells, five CR1632 = 3V x 5 = 15V (16mm ø - no modification of compartment required), readily available 8/2013 ≈$0.25 x 5 = $1.25 Stack of 5 too short for battery compartment. Requires a spacer - make it - wood dowel (light weight) wrapped in copper foil.

I bought a Triplett 310 on the advice of some pros at a big power company where I worked as a summer intern while at college over 40 years ago. I have owned many many VOM meters since but my Triplett 310 is still THE BEST! Just gave it to my nephew and bought myself a new one (310C)!! After using this ANALOG wonder you will throw rocks at your digital meters.
(Just remember to leave the selector lever setting on High AC volts before touching it to anything -when certain of no Potential Energy then switch to Ohms).
Put the Triplett 310 on your bucket list!

I too am a technician who occasionally needs an analog VOM. I knew an older technician for a major fire alarm company who swore by his old, company-issued Triplett 310. About four years ago, I purchased an older, used one that worked great until I dropped it. It was reliable and felt like a very sturdy, well-built meter. I soon purchased a new 310 thinking it was of the same quality as the one I once had.

I was wrong! the very first thing I noticed is, the new 310s feel flimsy and weigh significantly less than the older models. Upon using it for a few weeks, I also noticed the needle is very difficult to zero, and the ohms adjustment knob doesn't even allow someone to zero the meter. You can never get it quite on the zero mark, it's so jumpy and unpredictable that this meter is almost unusable. This is probably because of the potentiometer used to zero it, much like an old radio knob that gets "scratchy" when you adjust the volume. That was three years ago. Today, the meter is still very difficult to use accurately. I'm very disappointed in how a product that's been around for so long can be built so poorly.

I just purchased an older 310 used, it feels sturdy and well-built just like the other, and is dead-on accurate in resistance and voltage readings when compared to my Fluke DMM. I'll be proud to carry the old one in my tool bag. It's not often that a technician needs an analog meter, but they still have their place in the trades, and they need to last. Especially at what these sell for new.

As an electrician for 32 years, I still favor these types of meters over digital meters in some situations. Checking relay contacts, setting up balanced magnetic switches, continuity, Ohms... the needle movement gives a nice quick visual indication. If i need precision ill use my digital meter but this old school type is my favorite for trouble shooting.

This was produced in China, not in the US. The range switch on this unit is not like the original. It is not as "clicky" - has a completely different tactile feel, and is also painted a sickly, dull red color. The switch does not feel as if it will last a long time. The mirror that is behind the scale to correct parallax errors actually makes the problem worse. This is because the reflective material is actually a piece of plastic which is not glued flat to the the back of the scale. You can actually see warps in it.

I did not want to find out what else was wrong with this unit so I returned mine to Amazon for a refund. I place the fair market value of this analog meter at around $150. Let's get it there.

This is a great little meter,it is very accurate and easy to use. I test some telephone cables and you can check for high resistance that can cause problems for digital meters.

I had a Triplett meter at my first tech job many years ago when I was still in my teens. Now years later I found that I needed a reliable analog meter that I could trust. Yes, there are $3.00 multi-meters that you can buy at a flea market but if you do any real technical work and need something smaller, the Triplett is the meter. I still use Fluke digital meters for precise measuring but for trending and quick troubleshooting, analog is still the way to go. The Triplett 3018 is a solid meter in a compact size. The sliding lever is exact and easy to use with one hand when changes are required.

Many commented that the meters of years ago were more solid and accurate. This meter is rather light so I guess they took some things out of it. My biggest concern is that I was measuring a voltage. I got a reading of both 10vdc and 10vac. How could it be both? I had to pull out my Fluke and determine the correct voltage. But that is an unforgivable error if you are doing a quick power supply check.
