The Time 1048 is 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.

Common use of the 1048 is to simulate a transducer or measure the current flow in a transducer loop. As a process calibrator it can be used to check a 4 to 20 mA system in either source or measure modes of operation. The 24 V compliance voltage powering the loop when current source mode is selected.

In source mode the Time 1048 can test and calibrate meters, thermocouple indicators, data loggers. It can also be used for signal injection, semiconductor characterisation, or as a backing off source. In measure mode it can operate as a multimeter, accurately checking DC voltages and currents over 3 ranges.
