1.Do you think this problem is caused by Version of the Gk-604D?
Which one need to updating Handheld no.1442814 or no.1442815?
2. I saw it.
3.we done open data file with excel and save new only.(Did not edit Data file )
Yes, We used Probe No.1500858 on both handheld Units.
but we not obtained the consistent results and A+ ,A- Results shift to Positive.(see attached)
Normally, The Data from A- should be is Negative if A+ is Positive .
We used value coefficients of Probe No.1500858 is Zero Shift A=-28.2,Gage Factor A=1.0026 on both handheld Units.
So we thought this problem is caused by Probe No.1500858.
Anyway, We will performing another survey ensuring by Probe No.1500858 on both handheld units.(should be updating versions of the GK-604D application on handheld devices before another survey?)
