THE MODEL 467 USES UNIQUE TRIDYNAMIC® APPROACH
The Model 467 CRT Restorer/Analyzer has been designed by B & K-Precision to evaluate
most television picture tubes, computer terminal displays, or other cathode ray tubes
with a high degree of accuracy. This professional quality CRT tester utilizes solid state
digital muliplexing circuits which provide new testing capabilities. This unique
TriDynamic® approach to CRT testing makes it possible to test all types of CRT's -
even Trinitrons and in-line types - by using just one simple test procedure.
SPECIAL FEATURES
Each test function has been designed to provide more rapid testing, in addition to
reducing human error. These features include;
1. A control panel which guides the user easily through the correct test sequence.
2. Three precision meters that display emission from all 3 guns simultaneously, to
minimize testing time.
3. Simultaneous leakage measurements between all important elements. No
controls to adjust. Even cathode-to-cathode leakage can be detected.
4. Heater voltage, G1 voltage, and line voltage are precisely and simultaneously
indicated on the three meters.
5. Continuously variable heater voltage, which can be precisely set on the meter.
All common CRT heater voltages are premarked on the meter scale. The
voltages to G1 and G2 are continuously variable, permitting the tube to be
checked under conditions simulating its actual use in the receiver.
6. New color tracking feature which greatly reduces time required for determining
proper color gun tracking.
7. A new, greatly improved rejuvenation capability is provided for each gun
independently. The entire process is automatically timed and operated by
simply depressing the RESTORE button. The rejuvenate feature provides
maximum cathode restoration while at the same time minimizing the
possibility of cathode destruction.
8. Simplified automatic life test.
9. Function switching between rejuvenation and emission test permits instant
evaluation of restoration effectiveness.
10. New, improved, more versatile adapter set is included. It provides capability to
directly test more CRT types with fewer adapters than any other currently
available tester.
11. Continuity to focus electrodes is quickly checked by the simple push of a
button.
12. Short indicator lamp shows instantly when Gl-K short has been successfully
removed.
