Amprobe Am-520 Detailed Review
Most multimeter makers are currently obsessed with the safety of the user. That could perhaps explain why they have additional safety features such as the noncontact testing of voltage.
Safety has much to do with the design of the multimeter as with the safety rating.Amprobe AM-520 adds versatility to its already burgeoning reputation and can help you test different electrical properties.
Most appliances you will be working on might have electrical conductivity. We all know the dangers of electricity. It, therefore, follows that all multimeters need to be as safe as possible.
Noncontact testing is whereby a multimeter tests conductivity or any other electrical property without the user touching the circuit or component. This multimeter gives the ability to do noncontact testing of voltage, which means you cut down on the chances of getting any accidents.
Apart from the fact that you can use this multimeter in different environments, you can also use it for various tests. You can use it to test for capacitance, duty cycle, temperature, current, and voltage.
It can test voltage that is up to 600V in addition to AC and DC. Additionally, you can also use it to test resistance and microamps. It has flame sensors that make it possible to test for the microamps. The diode test also helps you to troubleshoot applications easily.
This multimeter comes with a large LCD screen that makes it easier for you to read the results. Additionally, the screen has a backlight that enables you to read it in low light.
The backlight also increases the contrast for when you need to use the multimeter in the daytime. The LCD also has an analog graph the makes it easier to read. Apart from that, it also shows you dual readings.
The data hold feature is an essential convenience feature in a multimeter. It enables you to freeze the results on the screen until you are ready to use them. That means it also stops the multimeter from switching itself if it has the auto-shutoff feature. This feature adds some convenience to using this multimeter.
Relative Zero, Maximum and Minimum Mode
These three modes make it easier for you to use the multimeter the next time. These modes remember the last reading and enable the multimeter to rest itself the next time you start it. The maximum and minimum mode readings ensure you don’t go below or surpass a specific reading value. Talk of convenience!
Safety should be a central feature of any instrument that has to deal with electrical power. This multimeter is relatively safe and has undergone numerous tests to ensure it is as safe as possible.
It is UL and CSA certified for safety. You can thus be sure you will be working with an instrument that won’t put your safety at risk. Furthermore, noncontact testing adds a layer of safety to the testing process.
The design of a specific tool comes into play when considering the ease of use or durability. With this multimeter, you won’t have to worry about such concerns since it has a rugged design that makes it quite durable.
The design is also simple enough for anyone to use it. It lacks much of the fancy features typical in other multimeters that make it harder to use them.
Who is This Multimeter Best for?
If you are an HVAC professional, you shouldn’t have trouble using this multimeter. However, it doesn’t mean it would be hard for any other person to use it. The simple design has a lot to do with why it is easy to use.
Convenience features such as the data hold also play a significant role in its being easy to use. Beginners won’t have too many problems using it.
- Easy to use
- Sturdy and durable
- Affordable and Versatile
- The auto-ranging isn’t that efficient
What We Didn’t Like
This multimeter, although exceptional, we have to admit the auto-ranging feature needs some work.
That’s because it at times isn’t that efficient and gives out inconsistent ranges that might lead to inaccurate results. Although the auto-ranging issues aren’t that common, we still feel it’s something we should mention. Related Article: Multimeter buying guide
We hope you’ve now made up your mind on whether you should choose this multimeter or not. As you can see, it has several features that should delight any HVAC professional.
- Voltage up too 600V AC/DC, AC/DC current and resistance, frequency
- Capacitance for checking startup capacitors, temperature and microamps for flame sensors
- Non-contact voltage detection and audible continuity
- Diode test and duty cycle for troubleshooting applications
