The manual for the BK Precision Model PR-261 provides detailed instructions on the setup, operation, and troubleshooting of near-field probes used for EMI pre-compliance testing, including the use of different probe types and battery operation. It emphasizes the importance of following safety guidelines, checking for mechanical damage upon unpacking, and ensuring the probes are used in appropriate environmental conditions to maintain their safe and effective operation.
Manual Overview
The BK Precision PR-261 Near Field Sniffer Probe manual provides detailed guidance on the use and maintenance of the probe set, which includes magnetic, electric, and high impedance probes. These probes are essential for EMI pre-compliance testing during product development, covering a frequency range from 100 kHz to over 1000 MHz. The manual emphasizes the importance of safety, advising users to ensure the probes are not used on live parts exceeding 40 V and to employ a safety isolation transformer when necessary. It also outlines the operating conditions, specifying a temperature range of +10°C to +40°C for operation and -40°C to +70°C for storage. Troubleshooting involves checking for visible damage or performance issues, particularly after transport or storage in unfavorable conditions. Calibration and adjustments are facilitated by matching the probes to the 50 Ohm inputs of spectrum analyzers or RF receivers. The manual stresses the importance of using the supplied power cable or rechargeable batteries to minimize environmental impact.
Quick Issues Covered
- Diagnose power-up failures with PR-261 near-field probe.
- Identify error codes related to electromagnetic interference.
- Use schematics for circuit tracing in RF field investigations.
Overview
The PR-261 is a toolkit designed for investigating RF electromagnetic fields, essential for EMI pre-compliance testing during product development. It includes three hand-held probes with built-in pre-amplifiers covering a frequency range from 100 kHz to over 1000 MHz. The set comprises a magnetic field probe, an electric field probe, and a high impedance probe, all matched to the 50 Ohm inputs of spectrum analyzers or RF-receivers. Power can be supplied via batteries, Ni-Cads, or a power cord connected to a Model 2625 or 2630.

Safety & Warnings
The probes have been designed and tested according to IEC Symbols Publication 1010-1 and CENELEC regulations EN 61010-1 for safety. Important safety information and warnings must be followed to ensure safe operation. The instrument should be made inoperative if protection is impaired, indicated by visible damage, failure to perform measurements, prolonged storage in unfavorable conditions, or severe transport stress. Measurements on parts live above 40 V are not permissible, and the probes must not be used on equipment that is not safety grounded. A safety isolation transformer should be used if there is doubt. The power supply should use the supplied cable or rechargeable batteries, and non-rechargeable batteries must be disposed of properly.
