Exceptional, versitile
There is so much to say. This tool is a great size and made with the highest quality materials. Anyone can use it. It is ergonomically designed, compact, works flawlessly with extremely accurate results. That it can be used for multiple purposes helps reduce the tools that get carried around. With the extra large clamps, we can get it around the largest wires. And the temperature sensor is an added plus. You can’t go wrong providing your crew with this tool. If you have a team of electricians working together, buy one for each team, and don’t forget yourself.
✔ Yes, I recommend this product.

Easy to read LCD screen show a accurate reading every time.
I have used Amprobe products for about 20 years now. They were first offered through my local hardware store. I will not buy any other brand. These units are accurate and very easy to use and have saved my bacon from getting zapped a few times when working in a hot environment. Thanks for the great service and would recommend to all of my fellow DYI friends.
✔ Yes, I recommend this product.

This is great service tool for frontline troubleshooting
Amprobe ACD-51NAV CAT IV Navigator™ Clamp On Meter 600A with Temperature
This Navigator Clamp Meter is now one of my daily use meters. I have been using a competitors meter for my HVAC troubleshooting calls years and now I’ve returned to the Amprobe brand. I have worked in the HVAC / Electrical trade for almost 30 years, as a field technician, and using electrical meters is a daily event. I am a HVAC / Electrical Service Instructor at the Union so buying and using meters is a very important part of my career.
Pros:
I found this meter is easy to handle and fits great into your hand.
The selection dial is easy to read with clear selection points.
I found the hold button strategically placed so you can use your thumb to press it.
Display light is clear white and lights up the entire display.
I found the display easy to understand with large numbers to ready in a tight location.
The navigation joystick allows you to make specific menu function selection changes and I found it easy to figure it out make menu changes on the go.
The LED work, light below the clamp jaws, is great when you are trying to see into a dark panel or box.
The battery indicator helps me to know the battery life that is remaining.
Capacitor testing is really easy with this meter.
Meter allows measurement of VFD’s with low pass filter
Cons:
The non-contact voltage detector is very sensitive and sometimes gives false readings.
The test leads do not allow for interchangeable lead tips
The piercing tips on the test leads don’t pierce the wiring insulation very well.
I would like the meter care to be more water resistant; our Northwest weather requires a better waterproof case.
✔ Yes, I recommend this product.

Excellent meter for doing hvac maintenance
Has many of the features an hvac technician needs volts, amps, resistance, capacitance and microamps. If you want to do air conditioning or motor efficiency this meter is the one to get. If you need to determine harmonics or phase rotation this is a plus feature.
✔ Yes, I recommend this product.

Great multimeter
Very good meter the large screen makes reading the meter easy and the inrush and wattage features are great to have. I have used the phase rotation function more times then I thought I would.
✔ Yes, I recommend this product.

ACD51NAV-In-Rush Current
I have had the ACD-51NAV for over a year and I enjoy being able to take LRA readings on compressor motors. This meter will also calculate watt readings-it has a selection on the meter. Very well built and at an affordable price.
Definitely recommend this meter.
✔ Yes, I recommend this product.

AWESOME
I use to use only fieldpiece, but after i got my first amprobe, i will never go back to anything but Amprobe.
i bought this meter after i got my swivel head clamp one, and let me tell you, you cant find anything better then this. Im a HVAC tech, and this meter has served me well and its got everything you need. The inrush feature on this is perfect for capturing the start up on compressors. Along with the 3 phrase testing too.
I reccommend this meter to anyone in the HVAC industry, its everything you need in a compact size, and the price cant be beat.
Thank you amprobe for the great meters, keep up the work. the industry needs it!
✔ Yes, I recommend this product.
