The BK Precision Model 510A Transistor Tester manual provides detailed instructions for setting up and operating the device, including in-circuit and out-of-circuit testing of transistors, FETs, and SCRs, as well as identifying device leads and determining device polarity. It also offers troubleshooting tips, such as recognizing limitations in testing certain semiconductor devices and understanding the significance of test results in different drive modes.
Manual Overview
The BK Precision Model 510A Transistor Tester manual provides detailed guidance on testing transistors, FETs, and SCRs both in-circuit and out-of-circuit. The device uses a high current, low duty-cycle pulse technique for in-circuit testing and a low current drive system for out-of-circuit checks. The manual emphasizes troubleshooting through a simple control interface with only two switches, minimizing the need for manual reference. The tester identifies device terminals automatically, indicating NPN or PNP polarity and distinguishing between device types. The manual outlines the use of the OFF/LO/HI switch, which powers the device and selects the testing mode. Error diagnostics are facilitated by the TEST LAMP and NPN/PNP lamps, which indicate device status. The manual also provides specifications for valid GOOD/BAD tests, including limiting shunt values and applied test currents. Calibration and adjustments are not required due to the device’s design, which includes a patented limited-energy pulse circuit for safe testing. The manual also includes board-level guidance for identifying and testing various semiconductor packages, emphasizing the importance of understanding device characteristics for accurate testing.
Quick Issues Covered
- Diagnose power-up failures with OFF/LO/HI switch settings.
- Identify lead faults using color-coded lead identification indicator.
- Use schematics for circuit tracing and device connection verification.
Overview

Controls & Indicators
OFF/LO/HI SWITCH: Applies power to the 510 when switched to the LO or HI positions. In the LO position, the 510 will identify all leads of a good transistor out-of-circuit, and in-circuit, if not heavily shunted. In the HI position, the 510 will test transistors in-circuit; FET’s and SCR’s both in and out-of-circuit. TEST LAMP: Flashes when 510 is ready to test. Turns off when either the NPN or PNP lamp indicates a good device. TEST SWITCH: Selects proper device connection for testing and lead identification. LEAD IDENTIFICATION INDICATOR: Identifies leads by color. NPN and PNP LAMPS: Indicate polarity of good devices.
