The 571 is a curve tracer. It can show the characteristic curves of PNP and NPN bipolar transistors, both N- and P-channel FETs, diodes (including Zener types), and SCRs. It is a microprocessor-controlled device, and user interaction is done through navigation keys. A typical sweep run takes about five seconds. It has a parallel printer output that can print graphics on Epson-protocol dot-matrix printers. | {{Oscilloscope Sidebar | | ||

One nice feature of the 571 is its ability to store a set of ''reference'' curves, which are displayed as a background for subsequent measurement runs. This makes comparison and matching between devices easy. | One nice feature of the 571 is its ability to store a set of ''reference'' curves, which are displayed as a background for subsequent measurement runs.

Because the nature of electronic component testing involves exposing components to sometimes hazardous voltages and operating conditions, at certain settings the 571 will refuse to start a measurement cycle until the user lowers the built-in hinged plastic shield over the socket area. This is to protect the user from both high voltage and high-velocity flying debris in the event of a catastrophic component failure during a test run. The shield is made of a thick high-impact plastic, and the 571 has an internal microswitch so its firmware knows if the shield is in the up or down position. | Because the nature of electronic component testing involves exposing components to sometimes hazardous voltages and operating conditions, at certain settings the 571 will refuse to start a measurement cycle until the user lowers the built-in hinged plastic shield over the socket area.
