The manual for the BK Precision high voltage probe covers setup, operation, and troubleshooting by instructing users on safety precautions, proper connection to earth ground, and the use of interchangeable probe tips for accurate voltage measurements. It also details the probe's compatibility with external voltmeters, its internal voltage divider function, and the importance of maintaining a clean and dry probe to prevent voltage creep.
Manual Overview
The BK Precision high voltage probe is designed for measuring DC voltages up to 40 kV and AC voltages up to 28 kV. It requires connection to an external voltmeter with a 10 MΩ input impedance. The probe features a 1000:1 divider ratio, meaning a 30 V reading on the voltmeter corresponds to 30,000 V. The device is housed in a durable ABS plastic case and includes interchangeable probe tips for different applications. For operation, ensure the probe is clean and dry, connect the alligator clip to an earth ground, and plug the banana plugs into the voltmeter. Select the appropriate voltage type and range on the meter. During use, keep one hand behind your back to minimize risk of electrical shock. The manual emphasizes safety precautions, such as working in a dry area and avoiding contact with conductive parts. The warranty covers defects for one year, excluding misuse or unauthorized repairs. For service, contact an authorized BK Precision service center.

Installation / Setup
The source does not provide specific information on installation or setup highlights such as wiring, clearances, calibration, or prerequisites.
Operation
Before taking any measurements, first connect the alligator clip of the probe to earth ground and ensure the connection is electrically good. Examine the probe to make sure it is clean and dry, as dirt, moisture, and grease can provide a creep path for voltage. If in doubt, wipe with a clean, dry, lint-free cloth. Ensure the appropriate tip is installed in the probe for measurement; use the round needle tip for general applications and the flat tip for CRTs, tightening by hand without using pliers. Connect the alligator clip of the probe to earth ground, ensuring the electrical connection is good. Plug the red and black banana plug leads of the probe into your meter or instrument, ensuring the ground lead from the probe is connected to the common ground of your instrument or meter. Select the voltage function at the meter or instrument, the voltage type (DC or AC), and the voltage range, typically 20 or 200 volts. Note that the probe multiplies the reading by 1000, so a reading of 30 V is actually 30,000 volts. With your free hand in your back pocket, touch the probe to the high voltage point and note the reading at the external meter, avoiding contact with any exposed metal parts.

Safety & Warnings
These steps outline the minimum, basic safety precautions that must be followed when using this high voltage probe. Before you use this instrument, read and thoroughly understand this information. You must have a thorough understanding of the hazards that may occur when working with high voltages and when using this probe. Failure to follow good safety practices could cause you serious personal harm, even death. Remember, high voltage kills if safety precautions are not followed!
1. In addition to these safety instructions, follow those given by the manufacturer of the device being checked.
2. Examine probe, make sure it is clean and dry. Dirt, moisture and grease can provide a creep path for voltage. If in doubt, wipe with a clean, dry, lint-free cloth.
3. Check floor in the test area. It must be dry, clean and free of oil. Never stand on a wet or damp floor.
4. Always connect the alligator clip of this probe to earth ground before taking any measurements.
5. Examine the entry to your high voltage test point. Make sure that you are able to bring the probe in to the test point. Also, make sure the tip is clear of wires, metal supports and other nearby conductive surfaces.
6. Verify that you are able to remain clear and avoid contact with any exposed metal and/or other conductive parts of the device being checked.
7. Only use one hand to hold the handle of the probe. Keep your free hand behind you, preferably in your hip pocket. This position helps avoid a situation where the voltage could flow across your chest should a mishap occur. Current flow across your chest is very damaging as it disturbs the rhythm of the heart.
8. Always work within sight and hearing of another person. If an accident occurs, you will be able to get aid quickly.
9. When handling a CRT, avoid touching the conductive coating before it’s discharged. Remember, it can hold a dangerous charge long after the set is turned off.
