5.4 Programming and function of keys
Function of keys in measurement mode :
After power - on, the signal converter enters the normal measuring mode. Display shows the actual measured
value of the parameter, units and arrow markers to identify parameter. A steady (non - blinking) display indicates
that there are no errors in measuring mode. Use the
é
key to get the next parameter on display. If display is in
cyclic mode (
Fct. 1.2.7 CYCLE DISP
as
YES
) the next parameter is displayed after every 6 seconds and
é
has no
function.
Use the
è
key to go to the programming mode. If
Fct. 3.2.2 ENTRY.CODE.1
is
YES
then converter will ask for
the code 1 password. Password is the sequence of 9 keys as given under
Fct. 3.2.3 CODE 1.
A wrong password
generates a set of unfamiliar characters on display. Press
E
key to go back to normal display.
Using the
E
key results in prompt for Code 2 password when converter is in measuring mode. Code 2 password is
predefined and reserved for KHRONE MARSHALL service person. Operator should not use
E
key at normal
display. If used by accident then give any arbitrary key sequence to Code 2 prompt until display gets back to
normal.

In cyclic mode the key has no function.

Function of keys in programming mode :
Programming and other functions are grouped in a menu tree structure. To navigate in the menu tree use keys as
follows :
è
To go into the branch i.e. from main menu level to submenu level or submenu level to function level. If you
were already at function level then that function will be executed.
é
Selects other options/branches at the same level.
E
Takes you one level back. If you were already at main menu level then this key takes you back to
measurement mode.
Programming functions involve one or more of the following types of data.
1.
Selecting an option from option list - initially present option is displayed in second line of display and
display blinks to indicate that there are other choices. Use the
é
key to scroll through all options one by one.
Using
E
will cause that option to be selected and also completes selection process.
2.
Entering a numeric value-Entering numeric data is very flexible in VFM 5090(I). You can enter +ve or -ve
number in floating point with /without exponent notation.
Formats
:
ddd.ddddd
floating point e.g.
1.2345678, -12.34567
dd. dddEdd
exponent e.g.
1.00000E6, -1.2345E-3
Method of entry : Initially the present value is displayed (in floating point format as far as possible) in the
first line of display. A flashing digit will change by using
é
key.
è
selects next digit position in sequence
and
E
terminates entry of the number.
