Amprobe 38XR-A [2727824] True RMS Digital Multimeter. The Amprobe 38XR-A digital multimeter is a True RMS auto ranging multimeter with an optical PC interface. Created primarily for engineers designing and troubleshooting industrial automation and control systems, the 38XR-A is a versatile instrument with the features and functions needed for a wide range of applications. Amprobe 38XR-A digital multimeters provide all basic multimeter functions and then some. The meter measures AC voltage to 750 V, DC voltage to 1000 V, AC/DC current to 10 A, resistance to 40 MΩ, temperature to 2372 °F, capacitance to 400 μF, and frequency to 10 MHz. The 38XR-A also has measures duty cycle, dBm, and has a 4 to 20mA loop current test and continuity beeper. In addition to the wide measurement ranges, the meter features high accuracy and resolution. Test results are displayed on the 4-3/4 digit LCD with 41-segment analog bar graph. The Amprobe 38XR-A includes an RS232 IR communication port for downloading measurement data (value, function, and range) to a PC. The optional 38SW-A Accessory Kit (software and cable) provides a graphical user interface for the PC to collect, store, and display measurement data. Other features of the meter include Min/Max, Average, Relative, Peak and Data Hold functions; input lead warning; and auto power off to save battery life. The multimeter has a separate door for easy battery and fuse access and is CAT IV 600 V safety rated.
