Manual Overview

The B&K Precision 1998 manual provides detailed procedures for testing and rejuvenating CRTs using models 467, 470, 480, and 490. It emphasizes safety by instructing users to discharge the high voltage anode supply before connecting the CRT tester. The manual outlines a step-by-step process for setting up the tester, including selecting the appropriate adapter and heater voltage, and adjusting controls to specified settings. Troubleshooting involves checking for excessive leakage and addressing issues like G1-K shorts, which can be resolved using the REMOVE SHORTS function. For emission issues, the CLEAN-BALANCE and REJUVENATE functions are used to restore CRT performance. The manual also details specific G1 voltage settings based on CRT markings and provides guidance on testing emission, tracking, life, and focus. For board-level guidance, it suggests using isolation transformers for unrepairable H-K leakage. The manual includes contact information for major CRT manufacturers for additional support and specifies that new setup charts are published biannually.

Quick Issues Covered

• Diagnose excessive H-K leakage; use isolation transformer if needed.
• Adjust G1 voltage based on CRT type for accurate testing.
• Restore emission levels if guns read BAD during tests.

Overview

BK Precision’s Setup Chart from September 1998 provides guidelines for testing and rejuvenating CRTs using B&K Precision CRT Tester/Rejuvenators. It includes general notes applicable to all tube types and specific instructions for models 467, 470, 480, and 490. The manual emphasizes safety precautions, such as discharging the high voltage anode supply before testing. It outlines steps for setup, testing, and restoring CRTs, including procedures for removing shorts, cleaning, balancing, and rejuvenating the picture tube. The chart also provides contact information for major CRT manufacturers for additional support.

Installation / Setup

Do not apply power to the CRT chassis during testing. Discharge the High Voltage Anode supply before connecting to the CRT tester. The 490B model uses CA adapters, but CR adapters can be used with a CR-MX cable adapter if CA adapters are unavailable. Set G1 voltage to 50V unless specified otherwise in the setup chart. For CRTs marked with special symbols, adjust G1 voltage accordingly. Prefix and suffix letters are generally omitted from CRT types unless specified. Monochrome CRTs should be tested in the RED/B&W position. For unlisted CRTs, contact the manufacturer for pin-outs or a compatible tube type.

Operation

The operation of B&K Precision CRT Tester/Rejuvenators involves several steps:

1. Set-Up:
– Ensure all controls are set fully counterclockwise and the G2 switch is set to NORM.
– Find the proper adapter and heater voltage from the SET-UP chart.
– Select the HTR RANGE, plug in the tube and power cord, and rotate the FUNCTION switch to SET-UP.
– Adjust the SET HTR to read the specified HTR VOLTS and set G1 voltage to 50 volts unless otherwise specified.
– Check LEAKAGE lamps; if they glow, it indicates excessive leakage.

2. Set Cutoff:
– Rotate the FUNCTION switch to SET CUTOFF position and adjust each G2 control to add one division to the meter reading.

3. Test:
– Rotate the FUNCTION switch to TEST position to check emission, tracking, life, and focus.
– For emission, all guns should read in the good region; if not, proceed to restoration steps.
– Tracking is checked by holding the TRACKING button and adjusting the control.
– Life expectancy is determined by observing emission levels while holding the LIFE button.
– Focus is tested by pressing the FOCUS test button.

4. Restore:
– If issues are detected, follow specific restoration steps such as REMOVE SHORTS, CLEAN BALANCE, or REJUVENATE depending on the problem identified during testing.

For models 470 and 480, the procedure is similar with slight variations in the steps for leakage checks and setting G1 bias.

Safety & Warnings

Do not apply power to the CRT chassis at any time during the test of any CRT. Completely discharge the High Voltage Anode supply of the CRT before connecting it to the CRT tester.
