Enter Display and Output Values
To scale the analog output, enter display value 1 and
a corresponding analog output value for this display,
and enter display value 2 and a corresponding analog
output value for this display value. This will provide a
linearly scaled analog output.
On decimal display models, enter the output value in
mA. On feet and inches display models, enter the
output value in µA.
The following diagram details setting the analog out-
put when the source is configured to display on the
top display of a decimal display model.
The following diagram details setting the analog out-
put when the source is configured to display on the
top display of a feet and inches display model.
The following diagram details setting the analog out-
put when the source is configured to display on the
bottom display.
See
on page
information on programming the display and output
values.
Note 1: On decimal display models, enter the output
value in mA. On feet and inches display models, enter
the output value in µA.
Note 2:The hundreds digit on the feet display does
not display 0 as a seven-segment
0
; instead 0 is
represented with three horizontal bars as shown.
•
Please note that when power is removed from the
scanner, the analog output will drop below 1 mA.
•
Consider this effect when designing any system
using the 4-20 mA output.
Math Channel (CV1 to CV4)
Programming (
MATH
)
The scanner includes four math channels, CV1 to
CV4. Each math channel is constructed by selecting a
math function and the desired parameters.
Note 1: The current math function selection will dis-
play as this menu item.
Note 2: Parameter 1, 2, and 3 will appear in the menu
structure based on their use in the selected math
function. See the table below for information on what
parameters are necessary for each math function. If
Constant is selected as the math function, the value
will be immediately entered.
