UEi Multimeters: The Importance of a Quality Meter

HVAC contractors know that a digital amp multimeter can be very important while out in the field.

Technology for meters has come a long way in the last 20 years. Modern multimeters are an example of just that, meters with multiple applications for day-to-day issues you’ll run into in the field.

Today we’re going to dissect UEi’s extensive line of multimeters and talk through the pros and cons of each while explaining some of the more unique applications available.

Specifically, we’ll focus on the UEi DL 379B, UEi DL 389B, UEi DL429B, UEi DL479, and the UEi DM393. These are all wonderful test instruments but sometimes it can be hard to tell which one is the right fit for the job. So, let’s dive into these 5 multimeters and give each the love they deserve!

This is one of the most popular and trusted meters for contractors nationwide. It comes with test leads, alligator clips, and the very sought-after dual display for viewing amperage and settings at the same time. It also includes a very handy lead holder attachment on the clamp making it easy to test multiple areas with your read lead. The functions on this meter are fit for any general HVAC contractor, appliance/handyman, technician, or electrician.

The UEi DL 389B is very similar to the UEi DL 379B across the board. The major differences have to do with the addition of True RMS technology . The UEi DL 379B widely works for most linear electrical load situations but the DL 389B allows the user to read nonlinear modulations. It accurately measures imperfect, non-sinusoidal waves. This is useful for advanced HVAC technicians looking to troubleshoot or test newer HVAC units or computerized control boards.

The biggest buying factor for the 400 series UEi clamp meter is a new Bluetooth feature. The UEi DL 429B allows users to connect their multimeter to their phones for readings without looking directly at the digital multimeter display. This comes in handy when your meter must reach tight, dark spaces out of the operator’s line of sight. It comes with a free app download that connects easily to the meter. This is a great option for anyone working on mini splits regularly.

The UEi DL 479 meter is a great, affordable option for beginner technicians in the HVAC world. As far as True RMS ready multimeters, this is one of the less expensive models available from UEi. One thing that sets it apart is the 1000V CAT 3 and 600V CAT 4 options. That’s a perfect range for anyone doing light commercial or residential work. There’s also a handy flashlight on the top of the device that runs when using the backlit display.
