Operating Basics To obtain the best performance from the P6339A probe, compensate the probe as needed, observe the maximum input voltage and make appropriate probe connections. Probe Compensation Due to variations in oscilloscope input characteristics, probe low-frequency compensation may need adjustment after moving the probe from one oscilloscope to another.

WARNING The following servicing instructions are for use only by qualified personnel. To avoid injury, do not perform any servicing other than that stated in the operating instructions unless you are qualified to do so. Refer to all safety summaries before performing any service.
Adjustment and Verification Procedures Use the following procedures to adjust and verify the P6339A Buffered Passive Probe to warranted specifications. Before beginning these procedures, photocopy the test record on pages 27 through 29 and use it to record test results. The recommended adjustment and verification interval is one year.
5. Set the offset button to the off position (button not illuminated). 6. Allow at least 20 minutes for the equipment to warm up. NOTE. Ambient temperature must be within 20_ C to 30_ C when you adjust the probe. P6339A Instruction Manual...
