setting is now complete.
ATTENTION
For CUSTOM unit in
transmitter with LINEAR output, you must set
both lower and upper display limits for values
to take effect. If you let either the lower or
upper display limit time out (after 30 seconds),
the meter discards both newly set values and
reverts back to the previously set values.
Display goes blank for a 1/2 second and
returns to display readout equal to 50%
output.
In this example, readout is 9, 990,000
CUSTOM unit for 50% display range of 0 to
19,990,000 CUSTOM for transmitter with
LINEAR output.

• If you have not yet set the lower display limit value for CUSTOM unit in a transmitter configured for
LINEAR output mode, the meter automatically enters the lower display setting function after it
displays previously set value, if applicable. Go to Table A-7, Step 3.
• If you have already set the lower display limit value, this completes the lower and upper display limits
setting function for CUSTOM unit in a transmitter configured for LINEAR output mode. Meter returns
to normal operation.
• If you have just set the upper display limit for Flow unit or CUSTOM unit in a transmitter configured
for SQUARE ROOT output mode, this completes the limit setting function. Meter returns to normal
operation.
