Ideal for calibration purposes, this DC current source can be used to source and measure current for testing and calibrating transducers, semiconductors, relays, switches and much more.

The 1021 is capable of outputting current from 0 to 100mA in 3 ranges: 0 to 99mA in 10μA steps, 0 to 9.999mA in 1μA steps and 0 to 999.9μA in 0.1μA steps. The tester's output voltage is adjustable from 14 to 40V with maximum output power of 2.4 watts. All generated results are accurate within 0.02% for added levels of precision.

For user protection, the 1021 is short circuit and overload protected. It also includes an LED voltage limit indicator. The tester's safety terminals are fully compatible with 4mm shrouded plugs plus standard plugs, bare wires and spade terminals.
