The manual for the B&K Precision Model 570 Handheld Linear IC Tester covers the setup and operation of the device, including powering it with batteries or a battery eliminator, switching it on, and selecting various test modes to evaluate linear ICs. It also provides troubleshooting guidance, such as performing a self-diagnosis test and interpreting error messages when the device encounters issues during testing.
Manual Overview
The BK Precision Model 570 Handheld Linear IC Tester manual provides detailed instructions for technicians on testing linear ICs. The device applies analog signals to IC inputs, measuring output voltages and comparing them with expected values. Discrepancies result in a FAIL indication, with faulty pins displayed on the LCD. For troubleshooting, the tester performs a self-diagnosis upon startup, displaying error codes if faults are detected. The manual emphasizes ensuring the test socket is empty during self-tests to avoid interference. The tester supports various operating modes, including single, loop, pass-loop, fail-loop, and search mode for unknown ICs. Technicians enter test numbers without manufacturer prefixes or suffixes, with the tester automatically selecting the correct test for ICs with similar numbers. The IC is inserted into a 16-pin ZIF socket, and the test is initiated by pressing the TEST/EXEC key. If the IC type is unsupported, an “Unknown” message appears. The manual includes an IC support list and notes any special requirements for specific ICs. Calibration and adjustments are implied through the test sequence, which checks IC functionality against predefined parameters.
Quick Issues Covered
- Self test diagnostics identify faults with error codes displayed.
- Low battery warning affects test result consistency.
- Battery eliminator recommended for prolonged use to prevent leakage.
Overview
The Model 570 Handheld Linear IC Tester is designed to test linear integrated circuits (ICs) for correct operation by applying necessary analogue signals and measuring output voltages, comparing them with expected values. It features an integral LCD display to indicate any discrepancies and faulty pins. The tester includes various facilities such as test loops for inspection, detecting intermittent faults, and a SEARCH function for identifying unknown ICs. It is powered by two 9V batteries or an external battery eliminator. The manual covers topics such as DC input, battery eliminator usage, switching on the device, operating modes, entering test numbers, testing ICs, and interpreting test results.

Installation / Setup
The Model 570 Handheld Linear IC Tester requires two 9V batteries for power or can be used with an external battery eliminator. Nickel-Cadmium batteries are permissible but must be removed for recharging. Batteries should be inserted correctly to avoid damage, and a low battery warning will display if the voltage is insufficient. The battery eliminator is recommended for prolonged use, and batteries should be removed during long periods of non-use to prevent leakage. To switch on the unit, press the ‘ON’ key, ensuring the test socket is empty to allow the self-diagnosis test to run without interference. The unit will power off after three minutes of inactivity to conserve battery life.
Operation
The Model 570 Handheld Linear IC Tester operates in several modes, selectable via the MODE/CLEAR key from the initial screen. The modes include SINGLE for executing a single test, LOOP for repeated testing regardless of result, PLOOP for repeated testing if the result is PASS, FLOOP for repeated testing if the result is FAIL, SEARCH for identifying unknown ICs, and DIAGS for executing a diagnostic self-test.
To enter test numbers, the desired test mode is selected, and the IC number is inputted. Mistakes can be cleared with the MODE/CLEAR key. Only numeric information is entered, excluding manufacturer prefixes, suffixes, and IC family information. The tester automatically determines the correct test for ICs with different pinouts or package types, but if the IC is faulty, a warning message will appear, allowing manual selection of the correct part number.
Testing involves inserting the IC into a 16-pin Zero Insertion Force (ZIF) socket, ensuring the lever is up before insertion and down after to secure the IC. The TEST/EXEC key initiates the test sequence, displaying “BUSY” during the process. If an invalid IC type number is entered, “Unknown” will be displayed, which can be cleared by entering another IC type number.

Basic Usage and Operation Tips
Before starting measurements, ensure the device is properly calibrated and the test leads are securely connected. Select the appropriate measurement mode using the rotary switch. For voltage measurements, connect the probes in parallel with the circuit; for current, connect them in series. Use the data hold button to freeze the displayed value when needed. Always start with the highest range if unsure of the expected measurement to prevent damage.
Troubleshooting and Maintenance
If the device displays erratic readings or fails to power on, check the battery status and replace it if necessary. Inspect test leads for any signs of wear or damage and replace them if compromised. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. For persistent issues, consult the full manual or contact authorized service centers.
Safety Reminder
Always observe proper safety precautions when using the Bk-precision-570. Avoid measuring voltages or currents beyond the device’s specified limits. Disconnect power before changing test leads or measurement settings. Use insulated gloves and tools when working with high voltages, and never operate the device in wet or explosive environments. Following these guidelines ensures safe and effective operation.
