When should I “zero adjust” the system

Kett Support asked 7 years ago

Do I need to do the zero adjustment every time I switch on the moisture meter? Sometimes it will sleep automatically after not using for a while, do I need to zero again after I turn it on

It’s recommended that you zero when
1.  You power up (to at least check)
2.  The instrument has run for at least two weeks straight (not normal on the handheld… more for our online/inline systems)
3.  You have a reason to doubt the moisture measurement
4.  You are going to calibrate (you want the system in a common baseline so you can combine values).
