This chapter explains how to perform the routine maintenance and calibration tasks
required to keep your calibrator in optimal operating condition. The tasks covered in this
chapter include the following.
• Replacing the fuse
• Cleaning the air filter and external surfaces
• Calibrating to external standards
• Calibrating the range
• Calibrating the wideband ac module
• Checking the calibration
For intensive maintenance tasks such as troubleshooting or repair, and for all procedures
that require opening the cover of the instrument, refer to the 5700A/5720A Series II

checking that traceability to national standards is being maintained by the normal
calibration procedure.
