Safety & Warnings
Normal use of test equipment, such as the Model 2522C oscilloscope, exposes users to electrical shock hazards, especially when testing in areas with high voltage. Electrical shock from as low as 35 volts can be dangerous and potentially lethal. To minimize risks, users should:
1. Avoid unnecessary exposure to high voltage and only remove equipment housings when necessary. Ensure equipment is turned off when making test connections in high-voltage circuits and discharge high-voltage capacitors after removing power.
2. Familiarize themselves with the equipment being tested, particularly the high voltage points, while being aware that high voltage may appear unexpectedly in defective equipment.
3. Use insulated floor materials or mats and work surfaces, ensuring they are dry.
4. Employ the “one hand in the pocket” technique to avoid creating a ground return path through the body.
5. Only touch the insulated portion of a probe, avoiding the exposed tip.
6. Be aware that ac line voltage may be present on 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 confirmed otherwise, and use an isolation transformer for measurements to avoid shock hazards and equipment damage.
8. Never work alone; someone should be nearby to provide aid if necessary. CPR and first aid training are recommended.

- Vertical sensitivity from 5 mV/div to 5 V/div
- Dual input channels with AC/DC coupling options
- Trigger modes: Auto, Normal, and Single Sweep
- Built-in calibration signal for probe compensation
- Compact and portable design with easy-to-read CRT display
Basic Usage and Operation Tips
To begin using the Bk-precision-2522c oscilloscope, connect the probe to the desired test point and select the appropriate input coupling (AC or DC). Adjust the vertical sensitivity and time base controls to properly scale the waveform on the screen. Use the trigger controls to stabilize repetitive signals for clear observation. Always start with higher voltage/div and slower time/div settings, then fine-tune for optimal waveform clarity.
Troubleshooting and Maintenance Notes
If the waveform is unstable or distorted, check the probe connections and ensure the calibration signal is properly compensated. Clean the device regularly with a dry cloth and avoid exposure to moisture or extreme temperatures. If the display remains blank, verify the power supply and fuse condition. For persistent issues, consult the detailed troubleshooting section in the manual.
Safety Reminder
Always ensure the oscilloscope and probes are properly grounded to prevent electric shock. Do not exceed the maximum input voltage ratings specified in the manual. When working with high voltages or sensitive circuits, take appropriate precautions and use insulated probes to ensure personal safety and protect the device.
