37XR-A True RMS Digital Multimeter with Component Logic Test

Feature packed, rugged and reliable

The Amprobe 37XR-A Digital Multimeter is a feature packed, rugged and reliable multimeter. It displays true-rms measurement on a low-light backlit LCD screen. Component and logic testing is used for troubleshooting electronics at the bench or on the job site. This multimeter features auto and manual ranging for measuring current, voltage, resistance, capacitance, frequency, inductance, duty cycles, logic states, and dBm function.

The meter comes with a set of detachable test leads with two alligator clips for measuring measure alternating current (AC) and direct current (DC) to 10 amp, AC voltage to 750 volts (V), DC voltage to 1,000V, resistance to 40 megaohms, capacitance to 400 microfarads, frequency to 10 megahertz (MHz), inductance to 40 henrys (H), duty cycles to 90%, and power to 50 decibels relative to miliwatts (dBm).

It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category II installations up to 1,000V (which covers large household appliances and devices connected to a fixed power supply, such as refrigerators and air conditioners), and category III installations up to 600V (which covers items used with enclosed building circuit installations, such as service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply). The meter comes with a magnetic strap that can be used to hang the meter on metal doors or fixtures.

Features:

The meter offers two ranging modes, auto or manual. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the measurement being taken. It can be switched to manual-ranging mode for applications where an instantaneous meter response is needed. True-rms sensing provides accurate reading when measuring both linear and non-linear loads.

The logic test reports the logic state of transistor-to-transistor (TTL) or complementary metal-oxide-semiconductor (CMOS) digital circuits in electronics. The maximum or minimum reading mode displays the highest or lowest reading in a session to track a sudden increase or decrease in readings, and the average function displays the average of the recorded maximum or minimum values.

The peak + or - function records peak positive or negative values for AC current and AC voltage. The relative zero mode stores a reading in memory to use as a zero point for subsequent readings, allowing for quick comparison of readings. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects whether the circuit's diodes work properly. The hold function keeps a reading on the display, even after the meter is disconnected. An auto power-off mode turns off the unit after 30 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced.

Style Name: 37XR-A: TRMS DMM w/Logic Test Verified Purchase
I purchased this DMM because it was the only one I found for a reasonable price that would measure both inductance and capacitance. I have been using it for a couple of weeks and have been very happy with it. I have not used all its features yet, but thus far, I have been more happy with it than the Fluke it replaced. It is easy to read and easy to use. All my probes fit and the readings have been as expected. Overall, very happy.

Style Name: 34XR-A: TRMS DMM w/Temp + Backlight Verified Purchase
I am an aircraft mechanic and needed a reliable meter that can perform all the functions this meter has. It was between this and a much more expensive Fluke meter. After using this meter extensively I must say it does everything it supposed to and works as well as the more expensive Fluke's. The meter is rated to 1000v and 10 amps which makes it useful for just about any application. I personally like the the dial selector more then the multifunction buttons found on the Fluke meters.

The problem I have found with this meter is high interference when measuring without the covers on the leads. The leads come with 2 unscrewable covers over the ends of the leads for, I asumme, more accurate readings since in areas where other voltage sources are close by, inaccurate readings can occur. These ends prevent from measuring something inside a hole and must be removed if you need a longer tip. The meter comes with alligator clips for the end of the leads and a temperature probe.

One other problem I had is with the temperature probe. It is a straightforward design of a small box that plugs into the probe receptacles of the meter. My probe arrived broken but I dismantled the box by simply popping the box apart, it comes apart in halves, and reattaching the wires that had come off their proper positions.

The meter comes with an extra fuse located under the panel of the rear of the meter. There is a small fuse and a large fuse. The large fuse is only accessible by completely removing the outer case and taking the back panel of the meter off. The smaller fuse is the only one that includes a replacement. The small fuses are the ones likely to go if measuring basic currents/voltages. I've found replacements for under 5 dollars.

Style Name: 37XR-A: TRMS DMM w/Logic Test Verified Purchase
This is a great digital multimeter for the price, and it's almost comparable to my fluke 179 DMM at work. It has way more features than most people will even need for home repairs. I think it's response time is a bit slow compared to my fluke, but it's better than most DMM's. It's lay out is pretty good, and it's been pretty easy to use so far. A great purchase for a home DIY or even a DIY field tech. It just falls a little short of my fluke 179 work meter.

I do like the leads that came with the unit but could not use the alligator clips with them.This meter is supposed to come with test leads that screw into the alligator clips, but they don't. I of course needed to use the alligator clips immediately so I had to order the correct leads.

I use meters for many purposes in my highly technical job. This is one of the best because it measure analog signal levels in addition to all the usual stuff. I have recommended this model and brand to my stuidents, colleagues and I even bought one for my home. There are too many cool features to list on this rugged meter so I will just say that I love it.

Style Name: 33XR-A: TRMS DMM w/Temp + Capacitance
Dudes I am not gonna lie. I own way to many multimeters. I own Fluke models 177,179, 8060a, 376,37,23 series II, 187, 863a and also Amprobe 34xra and 33xra. The amprobe 33XR-A is a sturdy safe basic manual ranging meter with a solid build, good battery life, and a complete set of features. I use mine in a testing jig measuring dc millivolts and it works wonderfully. This would make a great meter for a student or as a secondary meter for a professional when you want to monitor current and voltage at the same time or something like that. It comes with nice sturdy test leads, a manual written by someone who speaks english well, alligator clips, and a nice rubber holster with a magnet hanger that works very well. This is certainly a better meter than any of the offshore brands such as Mastech and UNI-T. I also have a drawer full of those chinese things and I never even consider using them.(I keep getting them for free from one of my suppliers).
The case is very solid and the range switch clicks into place nicely. The screen has decent contrast and the characters are large and easy to read. It holds it's own in accuracy against any of my Flukes, and It is pretty cool looking too.
If you are looking for a good budget meter this is a good one.

Style Name: 38XR-A: TRMS DMM w/PC Interface Verified Purchase
This is a durable multimeter that's accurate and works as advertised.

That said, the 38SW-A RS232 Software/Cable that this interfaces with (sold separately) is kind of clunky, so you may want to consider the Amprobe 37XR-A, which lacks the serial interfaces but can measure inductances -- a useful feature.

Although I don't have any major complaints, the device still has room for improvement. E.g. the continuity check is really slow (even if you touch the probes together, it takes a while before it beeps) and the selector switch is kind of mushy. In other words, it shares many of the shortcomings of the Amprobe 34XR-A that Dave Jones reviews in his $100 multimeter shootout (search youtube). That said, the innards of the 38XR-A are better than the innards of the 34XR-A. (E.g the 38XR-A dosen't have its piezoelectric buzzer poorly attached.)
