DM3068 (6 1/2 digit, basic accuracy 0.0035%) and DM2958E (5 1/2 digit, basic accuracy 0.015%) are two high-precision digital multimeters (DMMs) from RIGOL Technologies Inc., a leading manufacturer of electronic measurement instruments. These two models are designed for professional and industrial use, providing users with accurate and reliable measurements for their various applications.
DM3068 and DM2958E share some similarities in terms of features and design, but they also have distinct differences that make them suitable for different types of measurements. In this article, we will take a closer look at the key features of these two DMMs and compare their performance to help you choose the right one for your needs.
First, let’s take a look at DM3068, the higher-end model of the two. With a 6 1/2 digit display, it offers a higher resolution compared to the DM2958E, which has a 5 1/2 digit display. This means that DM3068 can read smaller changes in the measurement value, making it suitable for more precise measurements. The basic accuracy of DM3068 is also better at 0.0035%, compared to DM2958E’s 0.015%. This ensures that the readings from DM3068 are more reliable and closer to the true value of the measured quantity.
In addition to its high accuracy, DM3068 also offers a wide measurement range, making it versatile for various applications. It can measure DC voltage up to 1000V, AC voltage up to 750V, DC current up to 10A, AC current up to 10A, resistance up to 100MΩ, and frequency up to 100kHz. It also has a diode test function and can measure temperature using a thermocouple probe. These features make DM3068 suitable for use in electronics, research and development, and industrial maintenance.
DM2958E, on the other hand, is a more budget-friendly option for those who don’t require the high precision and wide measurement range of DM3068. It still offers a basic accuracy of 0.015%, which is suitable for most general-purpose applications. It has a slightly smaller measurement range compared to DM3068, with a maximum DC voltage of 600V, AC voltage of 600V, DC current of 10A, AC current of 10A, and resistance of 100MΩ. It also has a diode test function and can measure frequency up to 100kHz.
One notable feature of DM2958E is its built-in data logging function, which allows users to record and save measurement data for later analysis. This is especially useful for long-term monitoring and troubleshooting. DM3068 does not have this feature, but it can be added with the purchase of an optional data acquisition module.
Both DM3068 and DM2958E have a large 4.3-inch color LCD display, making it easy to read measurements and access various settings and functions. They also have a USB interface for data transfer and remote control, as well as a LAN interface for remote control and monitoring. These features make them suitable for use in automated testing systems.
In terms of design, both DMMs have a compact and rugged build, making them suitable for use in harsh industrial environments. They come with a protective holster and a magnetic hanger for hands-free operation. The buttons and rotary switch are also well-positioned for easy operation.
In conclusion, DM3068 and DM2958E are both high-quality and reliable DMMs that offer accurate and versatile measurements. DM3068 is the more advanced and higher-priced option, suitable for professional and industrial use, while DM2958E is a more affordable option for general-purpose applications. Whichever model you choose, you can be sure of getting precise and reliable measurements for your various needs.
