Hi, I have some CS616 that in the same soil are giving different periods in the same soil, a collegue told me to check if they are giving the referce period if I put them in air and water. I found the reference period in air into the manual but i can't find the reference period in water, someone can help me,please?
CS616 Manual, Page 4, Section 5
14 microseconds in air, 42 microseconds in tap water.
thank you so much
