When you are an ordinary user, you probably don’t need the most advanced features. So, having a multimeter that you understand, you can get more out of it.

Level of Versatility and Accuracy

In this case, they are usually opposite characteristics but complementary. One of the most important aspects is the precision that can be obtained with this type of tool. On the other hand, the specific technicians in this area use their meters for diagnosis.

Therefore, the resistance to this type of situation should be acceptable. In turn, it is important to consider a certain level of versatility and basic functionality. Thus, this allows for proper testing of current, amps, ohms, and volts.

So, an Avometer that is more accurate than versatile will then be more convenient.

Digital Counting

HVAC Multimeter Digital Counting

In this case, a certain number of digits can be found on the display in numbers. So, it is the counting of the display that is done every certain specific number of digits. In addition to this, you can see another type of measurement that can be counted with only one digit.

Generally, the count always starts from 0. If 2,000 is displayed, then the highest number will be 1999. Besides, as the maximum number is higher, then the level of accuracy also increases.

Therefore, the vast majority of these accessories provide a maximum number of 6000 and therefore four digits on the display. 

Reliability and Security

There are many models of multimeters that have certain safety certificates. To do so, each particular model must pass certain key controls and tests. In this case, the most important thing is to have a good level of security in the operation of the voltage checker.

In turn, this is because electricity is used in this type of tool. So, you can find different types of safety certificates. One of the most important aspects of security is that you are protected against certain common pitfalls. 

Some of these drawbacks are grounding problems, excessive spikes, arcing, voltage, and current. There are about four major categories to know the best use of each.

Therefore, the higher the certificate rating (CAT II, CAT III, CAT IV), then the more protection you will have with the surge and transient spikes. Along with this, you should establish the distance of this tool from the power supply.

So, this will let you know which CAT certification you should get. You will need CAT I when the connected tools are in a circuit. CAT II is required for internal switches. You will also need CAT III to use the switch panel. Also, most multimeters require CAT II or III.

Secondary Factors

In this case, although not important features, these aspects can enhance the proper functioning of an HVAC system.

Temperature Test Mode

A few multimeters can provide a certain temperature gauge. This is one aspect that allows the overall operation of the HVAC system to be optimized. With this feature, you will not need other tools to monitor different temperatures. So, this is a highly desirable feature.

LED Display Type

As with other types of electronic tools, the screen is another aspect that can be important. You can find two main types of displays today. On the one hand, you can get a bright display that can be easily read.

At the same time, the Avometer may also provide a backlit display. So, having one of these types of displays will be much better than a multimeter without a display.

Voltage Measurement

It is possible to measure or detect the voltage without connecting the cables. For that, the tester should be able to provide this particular feature. In other words, it is an alternative technique with a good level of efficiency and speed. This way you can start working more easily before opening the system panel.

Automatic Shutdown Option

You can find some multimeters that provide between 50 and almost 100 hours of use. This is usually done by including 9 volts in a battery.  So, if you want to extend the life of the built-in battery you can use this feature.

Simply put, the Avometer will turn off when not in use. This also conserves battery power. 

Total cost

Finally, the total cost of your next HVAC multimeter should match the quality of the same accessory. Of course, having a voltage tester that is too low in cost could result in poor quality.

At the same time, a tool with too high a cost is not necessarily the best option. It is important to purchase a tool that suits your needs and has an intermediate cost.
