Calibration/Maintenance  

 

Yoyo loggers are factory calibrated using dedicated equipment which is calibrated ac-
cording  to  ISO/IEC17025,  by  comparison  against  natural  standards,  natural  physical 
constraints or by ratio type measurements, using self-calibration techniques. 
 
To  ensure  that  measurements  are  reliable  and  correct  we  recommend  calibrating  the 
logger´s sensors within 12 months of purchase 
 
The logger itself only requires a minimum of maintenance. Verify O-Rings are clean and 
non-damaged and remove any dirt.
