The 78L/79L series regulator tester can test the output voltage, output voltage linear regulation rate, output voltage load regulation rate, static current, static current linear change rate, static current load change rate, input output voltage difference and other parameters of the 78L, 79L series three-terminal regulators.
The Kangsheng 78L/79L series regulator tester measures output voltage, linear regulation, load regulation, static current, and input‑output voltage difference of 78L and 79L three‑terminal regulators. It supports both manual testing with a test box and automatic testing via a robotic sorting system.
The device includes programmable precision voltage source, programmable electronic load, high‑speed test chip, indicator LEDs, a three‑section LCD, and a full set of switches and keyboard functions for selecting test items, modes, and parameters. Connections for the test unit, common bus, and robotic hand interface are provided. This manual is written in Chinese.

The tester can evaluate 78L and 79L series three‑terminal voltage regulators.
A programmable voltage source sets a voltage, the electronic load draws a current, and the difference between the input voltage and the measured output voltage is calculated.
The front panel includes LEDs for COUNT, RESULT, CONDITION, LIMIT, OFF, SETUP, TESTING, AUTO, MANUAL, CALIBRATION, and others to display status of the test and parameters.
