Manual Overview
The Bk Precision COND.-INSTRUCTIONS-MANUAL for models 480, 490, 467, and 470 provides detailed procedures for testing and rejuvenating CRTs. It emphasizes safety by instructing technicians to discharge the CRT’s high voltage supply before testing. The manual outlines specific G1 voltage settings based on CRT markings, with variations for different models. It includes a troubleshooting flow for emission, tracking, life, and focus tests. If emission is poor, the manual advises using the RESTORE function. For tracking issues, the TRACKING button and control are used to adjust readings. The LIFE test assesses emission stability, with poor results leading to restoration steps. Focus is checked via a dedicated test button. The manual also provides guidance on removing shorts and balancing, with multiple operations sometimes required. For persistent issues, the REJUVENATE function is recommended. The manual includes a setup chart for adapter and heater voltage selection, ensuring proper initial configuration.
Quick Issues Covered
- Diagnose CRT emission issues with emission test procedure.
- Identify and remove G1-K shorts using REMOVE SHORTS button.
- Adjust G2 controls for proper cutoff settings.

Installation / Setup
The setup highlights for the CRT Tester/Rejuvenator models 480, 490, 467, and 470 include the following key points:
1. Ensure the CRT’s high voltage (anode) supply is completely discharged before connecting to the tester, and do not apply power to the chassis during testing.
2. Set G1 voltage to 50V unless specified otherwise in the setup chart. Adjustments are required for CRTs marked with specific symbols, indicating different G1 voltage settings.
3. Red and Green or Red and Blue guns may need to be interchanged for testing, as indicated by specific markings.
4. Adapters not supplied with the tester can be ordered separately.
5. Prefix and suffix letters are generally omitted from CRT types unless specified.
6. Monochrome CRTs should be tested on the RED/B&W position unless noted otherwise.
7. The setup includes over 100 new CRT types with specific adapters.
The simplified test procedure involves setting controls, selecting the appropriate adapter and heater voltage, and conducting various tests such as emission, tracking, life, and focus. If issues are detected, steps for restoring the picture tube, including removing shorts and rejuvenating, are provided.
Operation
The operation of the CRT Tester/Rejuvenator involves several steps. First, ensure that power is not applied to the chassis during testing and discharge the high voltage supply of the CRT before connecting it to the tester. Set the G1 voltage according to specific CRT markings, and note any gun interchanges required for testing. Adapters for different CRT types may be needed and are available separately. For monochrome CRTs, use the RED/B&W position. The setup involves setting all controls counterclockwise, selecting the proper adapter and heater voltage, and adjusting the SET HTR to the specified volts. The function switch is used to test emission, tracking, life, and focus. If issues are found, steps for restoring the picture tube, such as removing shorts, cleaning, balancing, and rejuvenating, are provided.
