NorthTree Associates Announces New OWON XDM Series Benchtop Digital Multimeters

NorthTree Associates introduces the OWON XDM Series of Benchtop Multimeters. These powerful OWON multimeters come in two versions: XDM3041 which has a 4.5 digital resolution and the XDM3051 which has a 5.5 digital resolution. Both are designed for when a simple handheld multimeter doesn’t have enough capabilities for a user to view a reading in enough detail. (CLICK HERE to see specifications)

The OWON XDM series benchtop multimeters have a 4 inches LCD screen display, 480*320 pixels high resolution, 4.5 or 5.5 digit display accuracy (200000 counts in max). To add to the strength of these units, each XDM multimeter has up to 150 readings per second measurement speed. Also included are True RMS AC voltage/current measurement, smart voice-reading accessibility where the value can be read out, and support for Wi-Fi control through the use of a smart phone.

Operational modes include a data-logger mode which provides a user the ability to record, view, and analyze trends in readings. Users can set up the record interval (5ms in minimum) and max number of readings (1M points for internal storage, 10M points for USB Flash Disk). Data measured by the OWON XDM benchtop multimeter will be recorded and gathered into a trend chart, which makes it easy for users to view data statistics. Readings available are: bar meter, trend chart, and a histogram display for a convenient view. The OWON XDM benchtop multimeters have a dual display capability, 1GB internal memory, and support for external Flash Disk storage. Interfaces include USB Device, USB host, and LAN. A SCPI programming manual is provided, which enables remote control and is compatible with popular multimeter commands list.

In addition to representing the OWON XDM Series Benchtop Multimeters, NorthTree Associates also represents other product lines from OWON. These product lines include the customizable XDS Series n-in-1 Multi-Function Oscilloscopes, MSO Series Mixed Signal Oscilloscopes, HDS Series Handheld Oscilloscopes, Multimeters, AG-S Arbitrary Waveform Generators, and DC Power Supplies.

Multimeter: The Swiss Knife of Electronic Test & Measurement Tools

Main View

Recently, there has been a move towards increasing the functionality of many Electronic Test & Measurement tools that engineers use. The supposition is if one tool can do multiple tasks, engineers will need fewer tools, which can mean fewer tools on the workbench and fewer tools to calibrate. However, it has been indicated additional functions may limit the effectiveness of a tool to complete its primary task and any secondary features may not perform as well as a single-purpose product.

A multimeter is a multipurpose tester that has been a commonly used test tool that has been around a long time. Although analog multimeters are still being used, most multimeters now are digital. For engineers, it is a must have portable tool.

The latest DMM models have increased capabilities along with wireless functionality, and virtually limitless options. A single multimeter can meet varying needs.
Engineers may be more interested in fast go/no-go (noncontact) testing for voltage presence, and low-impedance modes for preventing false readings caused by ghost voltage.

Instead of searching for a digital multimeter that has 20 or 30 dial positions to cover every possible measurement, engineers should look for a DMM with measurement capabilities that fit their most common tasks. Wireless communications is a common feature of digital multimeters. These units take a single, momentary measurement and stores it in a database. Having the capability to store readings can prove helpful when conducting a series of readings that need to be logged. Taking it a step further, advanced DMMs offer Bluetooth capabilities to stream readings to a mobile device which would display readings remotely. Using a smartphone or tablet for remote viewing can help improve safety and also make it easier to operate equipment not immediately adjacent to the point of measurement.

Current multimeters are more versatile beyond the scope of standard multiple measurement modes. For example, a low-pass filter can ensure precision readings even when signals are noisy. It would be useful for working on variable frequency drives [VFDs]. Low Z mode does not allow so-called ‘ghost voltage’ to affect readings. Point-and-shoot infrared surface temperature measurement is a popular option on multimeters.

Also, richer, higher quality color displays has increased the usability of multimeters. High-contrast, dot-matrix LCDs are easier to read and brings the multimeter display beyond numerical values and labels and to a more advanced graphical reading displays for better testing results. A side benefit of being able to incorporate mobile capabilities is connectivity with other tools like infrared cameras. A multimeter can transmit electrical readings to an infrared camera, which can imprint those readings on related thermal images for effective testing and documentation.

There are now two distinct types of multimeters: units with high display count and accuracy for electronics engineers and units with high CAT safety ratings (IEC 61010) with acceptable functions for the electrical engineer or field engineer. If portable durability is needed, a user should check to see durability specifications.
