Buying a Digital Multimeter: What Do Engineers Need to Consider?

Those that have been operating in the HVAC industry for some time will know the importance of having the right type of multimeter on hand.

However, those who are approaching the industry for the first time may be unsure of what to look for in relation to a multimeter.

Having the most features doesn’t necessarily mean a multimeter will be suitable for an engineer. As such, engineers need to look at what applications they work with and then decide based on this.

As well as considering the application an engineer works with now, it can also be a good idea to consider whether what potential applications could be worked on in the future.

There’s no problem in upgrading at a later date, but in some instances, it can be more cost-effective if an engineer knows in advance.

The following is an overview of the factors that need to be considered when investing in a digital multimeter or upgrading an existing one.

Why Choose a Digital Multimeter?

Although some may have used a digital multimeter throughout their career, others may be more familiar with the analogue equivalent.

These types of multimeters can be appealing because of their cheap price, but the savings could pale in comparison to the things that could potentially go wrong when using one out in the field.

One of the main reasons digital multimeters have become so popular is because of the accuracy they can offer engineers.

Trying to capture an accurate reading was difficult because of the dial, and in some instances, the needles would often fluctuate so much that a reading was impossible.

In many instances, an engineer will be using a digital multimeter, but those still using an analogue equivalent are advised to upgrade as soon as possible.

Considering the Features

There are plenty of digital multimeters that are more than up the task ay hand, but it’s still important to ensure that it has the right features.

For example, some digital multimeters can measure voltage, current and resistance, whereas others may only be able to do one or two of the three.

There’s also the ranging to consider. A digital multimeter can offer auto-ranging, but the engineer needs to ensure that the digital multimeter comes with this as standard.

However, it’s important not to purchase a cheap digital multimeter with this feature, as engineers could find it unreliable in the field.

The importance of manual and auto-ranging can be subjective, but there’s enough choice on the market that can cater to both camps, so it’s simply a case of the engineer deciding what works for them best.

Many also find that the data-logging features are beneficial so the engineer will need to consider what form of setup works for them best i.e. a Bluetooth dongle.

Buying a Professional Digital Multimeter

Although it’s beneficial to have a digital multimeter, this doesn’t mean that any digital multimeter will do, especially when being used in the field.

Cheap digital multimeters may be fine for hobbyist, but those operating in the field need to ensure that the digital multimeter is reliable and safe.

Fortunately, finding the right type of digital multimeter is much easier once you have found the right supplier.

HVACTOOLS has been supplying the HVAC industry with reliable tools and devices for several years and ensures that all its stock has been put through rigorous checks.

The following is an overview of some of the digital multimeters popular with HVAC engineers

The Importance of Using the Right Supplier

When choosing a digital multimeter it’s important to concentrate on the value of the digital multimeter as opposed to the price alone.

In some instances, this can be a difficult process but dealing with a supplier that has knowledge and expertise in the sector can be of great benefit, especially for the HVAC industry.

As well as ensuring the equipment is safe, an engineer must also ensure that the devices they purchase are suitable for them.

In this regard, it can be beneficial to use a supplier that not only offers warranties on many of its goods, but also a satisfaction guarantee.

Not only does HVACTOOLS offer warranties on its digital multimeters, but also reinforces a satisfaction guarantee that allows engineers to return their purchase for a full refund.

Auto-Ranging UT61C Digital Multimeter

Not only is the UT61C affordable, but it also offers several features that no HVAC engineer should go without.

The multimeter can measure AC/DC current and voltage, diode, continuity, resistance, hFE and temperature.

As always, the UT61C conforms to CAT.III 1000V, CAT.IV 600V and has been used in many different settings including labs the HVAC industry and the automotive sector.

Findings can also be uploaded via the included software for further analysis.

Flex Clamp True RMS

The Flex Clamp True RMS showcases just how diverse a digital multimeter can be. Despite its unique design, the Flex Clamp can still offer the everyday HVAC engineer several features at the touch of a button.

This digital multimeter is designed using Rogowski flex coil, making it the ideal for awkward spaces. It can test up to 3000A AC current and has additional features that include a backlight, a data hold option and auto power-off.

600A True RMS Digital Clamp Meter

True RMS has become a desired feature in many digital multimeters as it contributes towards more accurate readings.

The True RMS Digital Clamp Meter not only offers True RMS, but also a data hold feature and LCD backlight that makes reading measurements less of a chore in darkened conditions.

No digital multimeter will be suitable for each and every engineer, but knowing what the multimeter has to contend with can ensure that the right choice is made in the first instance.
