The Amprobe 37XR-A Digital Multimeter is a robust and versatile tool designed for professional troubleshooting, whether at the bench or on the job site. It offers true RMS (root mean square) measurement for accurate readings of non-linear loads, making it a reliable choice for complex electrical diagnostics.

This model is packed with advanced features to enhance productivity and safety. It includes a bright backlight for low-light conditions and provides an input warning tone to alert you if test leads are placed in the wrong jack. For component-level work, it features integrated component and logic testing capabilities.

Key Functions and Performance

The multimeter provides a comprehensive suite of measurement functions, including AC/DC voltage up to 1000V DC and 750V AC, AC/DC current up to 10A, resistance, capacitance, and frequency. The 10A current inputs are fully safety fused for user protection. A continuity beeper with an audible tone allows for quick circuit checks without needing to look at the display.

Data recording and analysis are made easy with min/max, average, relative, and peak hold functions, alongside a standard data hold button. The auto-ranging feature and a high-contrast 4-3/4 digit LCD display with 10,000 counts and a 41-segment analogue bar graph provide clear, detailed readings. The display updates at a nominal rate of 2 times per second.

Design and Usability

Designed for durability and convenience, the 37XR-A features a separate compartment door for easy access to the 9V battery and fuses, facilitating quick replacements. An auto power-off function helps conserve battery life during extended periods of non-use. The included Magne-Grip™ holder with a hanging strap offers versatile hands-free placement on metallic surfaces.
