The manual for the B&K Precision 10 MHz Oscilloscope models 1466A and 1476A provides detailed instructions for setup, operation, and troubleshooting, including safety precautions, initial starting procedures, and various measurement techniques such as voltage, time, and frequency measurements. It also covers dual-trace applications, optional accessories, periodic adjustments, and calibration checks to ensure accurate and safe use of the oscilloscope.
Manual Overview
The B&K Precision Models 1466A and 1476A oscilloscopes are designed for single and dual trace applications with a 10 MHz bandwidth. The manual emphasizes safety precautions to prevent electrical shock, especially when working with high voltage equipment. It advises using isolation transformers for “hot chassis” equipment and recommends never working alone. Troubleshooting guidance includes understanding error codes and diagnostics, with a focus on calibration and adjustments. The oscilloscopes offer features such as selectable internal, line, or external triggering, and a high sensitivity of 2 mV/div for the full bandwidth. Calibration checks and periodic adjustments are essential for maintaining accuracy, with a built-in probe adjust square wave generator for probe compensation. The manual provides board-level guidance for repair and servicing, ensuring technicians can effectively diagnose and resolve issues.
Quick Issues Covered
- Diagnose power-up failures with initial starting procedure guidance.
- Resolve calibration issues with periodic adjustments and calibration check.
- Utilize schematics for effective circuit tracing and troubleshooting.

Safety & Warnings
Normal use of test equipment, such as oscilloscopes, exposes users to electrical shock hazards, especially when testing in areas with exposed high voltage. A current of 10 milliamps passing through the heart can be fatal, and voltages as low as 35 volts can be dangerous. To minimize risks, follow these precautions:
1. Avoid unnecessary exposure to high voltage. Remove housings and covers only when necessary and turn off equipment when making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power.
2. Familiarize yourself with the equipment being tested and locate high voltage points. Be aware that high voltage may appear unexpectedly in defective equipment.
3. Use insulated floor material or a large, insulated floor mat to stand on, and ensure work surfaces are not damp or wet.
4. Use the “one hand in the pocket” technique while handling an instrument probe to avoid providing a ground return path.
5. Touch only the insulated portion of a probe, never the exposed tip.
6. Remember that ac line voltage is usually present on some power input circuits whenever equipment is connected to an ac outlet, even if turned off.
7. Treat all two-wire ac powered equipment as “hot chassis” unless certain it has an isolated or earth ground chassis. Use an isolation transformer for measurements in “hot chassis” equipment.
8. Never work alone. Have someone nearby to render aid if necessary. CPR training is recommended.
