Setting Numeric Values
The numeric values are set using the Right and Up-
Arrow buttons. Press Right-Arrow to select next digit
and Up-Arrow to increment digit value. The selected
digit will flash.
Press and hold Up-Arrow to auto-increment the
display value. If you have made a mistake or would
like to enter a new value, select the left-most digit and
press and hold the Right-Arrow button until all digits
reset to zero.
Press the Enter button at any time to accept a setting
or Menu button to exit without saving changes.
Note: the underscore in the graphic below is provided
to show which digit would be flashing.
Scaling the 4-20 mA Input (SCALE)
The 4-20 mA input can be scaled to the appropriate
values for a given application. The 4 mA input
(input 1) should have a corresponding display value
(display 1) which represents the low end of the pro-
cess value range being measured by the transmitter.
Likewise, the 20 mA input (input 2) should have a
display value (display 2) which represents the high
end of the process value range.
For example: If the meter is used to display the level
of a 100 foot tall tank, the transmitter will send a 4 mA
signal when the tank is empty and a 20 mA signal
when the tank is full. The meter should be scaled
such that 4 mA corresponds to a display of 0 and 20
mA to a display of 100. If the application required the
meter to display how much room was left in the tank,
the meter could be reversed scaled such that a 4 mA
input displays 100 and a 20 mA input displays 0.
Processes which require a non-linear scale can be
accommodated using the linear (LINEAR), exponent
(EXPONENT), square root (SQROOT), and round hori-
zontal tank (RH TANK) functions available in the
Advanced menu. See Signal Input Conditioning
Functions (FUNCTION) on page 30.
A signal source is not needed to scale the meter;
simply program the inputs and corresponding display
values.
