A portable instrument that operates as a current and voltage source and a multi-purpose loop calibrator. High performance and simple operation make it suitable for R&D, service, process control engineers, and calibration technicians. As a versatile handheld calibrator, the source and measure capabilities with 0.02 % accuracy mean the 1048 is a compact solution for most simulation and test applications.
The 1048 combines the advantages of digital accuracy with analog control. Based on the popular functionality of the 1044 calibrator, the 1048 offers higher voltage and current across the three ranges, and improved accuracy. The additional features of transmitter simulation, sink loop control, output stepping and ramping, and incremental fine adjustment make the instrument ideal for use in the process industry.
The large, easy to read 4.5 digit LCD display shows the actual output, even when the connected load exceeds the specifications. This important feature eliminates the risk of large errors when connecting to unknown loads. The display also indicates if the battery becomes critically low.
