Instruments
Each SIGLENT product sold has passed quality and calibration testing prior to leaving the manufacturing floor. Each instrument comes with a Certificate of Calibration that is traceable to an NMI (NIST in the USA, NIM in China, etc..).
Here is a sample of our Certificate of Calibration:
In early 2020, we revised our calibration certificates to reflect an extension to the calibration interval to adjust for time spent in a warehouse/storage:
Here is the new statement:
SIGLENT has determined that the factory calibration of this instrument is not significantly affected by storage of up to 180 days before first-time use. Cal Interval should start at the time the unit is placed in service or 180 days past the “Date of Calibration” on the certificate received with the unit.
Here is an example of the full statement and calculations for determining the validity of the certificate:
