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,
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.
Bytes
this entry is used with certain instruments which require a 2
bytes to send
all
data to the logger, (i.e. Hi-Res In-
terface, Water Level Instrument). Most raw data in-
struments require only one byte. To display time in
the format a 4 byte input is required.
Formula
this entry allows the user to select a defined formula
from a list of pre defined formulas or to display the
raw logger value.
Select the appropriate formula for your application from the list below

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
