Activate FtS and
FtE with setup
program
Ex-factory, both parameters are not visible at the device and have to be activated first.
h Connect the device to the PC and start the setup program
h Establisch a connection to the device
h Make a double click on Undocumented parameters
h Click on check box at Parameter 17 (a tick shall appear)
h Save the setup file and execute Data transfer to device
Now the parameters FtS and FtE are visible in the Configuration level.
Principle The customised fine tuning (= fine adjustment) is used to correct the values displayed
by the device. This may be necessary, for example, after a system validation, if the
displayed values no longer coincide with the actual values at the point where the
measurement is taken.
Using a reference measuring instrument, two measured values are determined which
should be as far apart as possible (start value, end value). Ensure that the measuring
conditions are stable. Enter the reference value found as the start value (FtS) or end
value (FtE) on the device to be adjusted.
