Calibration certificate

Dear Tektronix team,

I have faced with an issue regarding calibration certificate for our equipment. 
For some of the reason the certificate was lost.
Do you store all certificates in your database?
If yes, can i ask to send me the calibration certificate via e-mail? 

Our equipment is 
Model: 2281S-20-6 Precision DC Supply & Battery Simulator
ID number: 4479479

Thank you in advance,
Serhii

Thanks,
Chuck

Many thanks!
