Manual Overview
The B+K Precision Model 2190B oscilloscope manual provides detailed guidance on troubleshooting, diagnostics, and calibration. For troubleshooting, the manual emphasizes safety precautions due to the risk of electrical shock, especially when working with high voltage. It advises using isolation transformers for “hot chassis” equipment and stresses the importance of not working alone. The manual includes a section on error codes and diagnostics, although specifics are not detailed in the provided text. Calibration and adjustments are crucial for accurate measurements; the oscilloscope features calibrated voltage and time measurements with adjustable ranges. The manual outlines procedures for periodic adjustments and calibration checks to maintain accuracy. Board-level guidance is not explicitly mentioned, but the manual likely includes instructions for component-level troubleshooting and repair. The oscilloscope’s dual-trace capability allows for simultaneous waveform display, with features such as delayed sweep and X-Y operation enhancing its diagnostic utility.
Quick Issues Covered
- Diagnose power-up failures with initial starting procedure guidance.
- Calibrate voltage measurements using 10 calibrated ranges from 5 mV/div.
- Use schematics for circuit tracing and troubleshooting.
Overview
The BK Precision Model 2190B is a 100 MHz dual-trace oscilloscope known for being one of the most economical options on the market while still offering high-performance features. It includes a delayed time base, bandwidth limiter, and Y axis output. The oscilloscope is designed for high sensitivity with 5 mV/div sensitivity for full bandwidth and offers calibrated voltage and time measurements. It features a rectangular CRT with a large viewing area and dual trace capabilities, allowing for the display of two waveforms simultaneously. The oscilloscope also supports algebraic addition or subtraction of waveforms for differential voltage and distortion measurements. It has a wide bandwidth and fast rise time, with a maximum sweep speed of 2 ns/div. The manual covers various aspects such as test instrument safety, features, specifications, controls and indicators, operating instructions, maintenance, and an appendix with additional information.

Safety & Warnings
Normal use of test equipment like the oscilloscope exposes users to potential electrical shock hazards, especially when testing near 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 mitigate risks, the manual advises:
– Avoid unnecessary exposure to high voltage.
– Turn off equipment when making high-voltage connections and discharge capacitors after power removal.
– Familiarize yourself with the equipment and its high-voltage points.
– Use insulated materials for flooring and work surfaces, ensuring they are dry.
– Employ the “one hand in the pocket” technique to avoid creating a circuit through your body.
– Only touch the insulated parts of probes.
– Be aware that AC line voltage may be present even when equipment is off.
– Treat two-wire AC powered equipment as “hot chassis” and use an isolation transformer for measurements.
– Never work alone and have someone nearby for assistance. CPR training is recommended.
