Recertification
The following will be provided with a recertified kit:
• a new calibration sticker affixed to the case
• a certificate of calibration
• a calibration report for each device in the kit listing measured values, specifications, and uncertainties
NOTE A list of NIST traceable numbers may be purchased upon request to be included in the
calibration report.
Keysight Technologies offers a Standard calibration for the recertification of the kit. For more information,
contact Keysight Technologies. Refer to “Contacting Keysight” on page 6-4 for a list of offices.
How Often to Recertify
The suggested initial interval for recertification is 12 months or sooner. The actual need for recertification
depends on the use of the kit. After reviewing the results of the initial recertification, you may establish a
different recertification interval that reflects the usage and wear of the kit.
NOTE The recertification interval should begin on the date the kit is first used after the
recertification date.
