More often than not, the calibration of a process control loop requires simultaneous measurement with a DMM and signal generation. The new Keysight (formerly Agilent) U1401A gives you a two-in-one meter for just that.
It comes with a full compliment of DMM measurement functions including AC and DC volts, current, temperature, frequency and continuity tests. It also provides recording functions such as Hold, Min, Max, Average and data logging to a PC via the optional IR to USB cable.
In addition to mA, the calibrator can also output voltage and a square wave at various frequencies.
