7.3 USER DEFINED SCREEN FORMAT
This screen format allows the user to set up and save a custom designed for- mat for a specific application. This routine is initialised by pressing the "E" key. The FTU will then prompt the user to enter in:
Offset,
Bytes
this is to select the chosen memory byte to be displayed or altered. Up to 12 bytes can be displayed on the
screen at one time.
If an offset larger than 11 is chosen then previous bytes must be removed to make room for the chosen
byte. This feature allows the user to skip over cer- tain bytes and yet display others.
this entry is used with certain instruments which require a 2 bytes to send all data to the logger, (i.e.

If formulas RYVS have been selected then the FTU will respond with a prompt for the user to enter the value of the reference resistor used with the transducer.
If the formulas FH have been selected then the FTU will prompt with a line “Min value?”. The minimum desired vaIue for the scaling should then be
