2. Press the left and right configuration buttons simultaneously and release
them immediately.
3. To move the decimal point to the desired location, press the left
configuration button. Note that the decimal point wraps around.
4. To scroll through the mode options, press the right configuration button
repeatedly until the desired mode is displayed. See Table 6-1.
Store the Information 5. Press both configuration buttons simultaneously for two seconds. Note
that the meter displays “----” for approximately 7.5 seconds while the
information is being stored.

6. Press t he left button for two seconds.
7. To decrement the display numbers, press the left configuration button and
to increment the numbers, press the right configuration button. Set the
numbers between –999 and 1000.
8. To store the information, press both configuratio n buttons simultaneously

9. Press the right button for two seconds.
10. To decrement the display numbers, press the left configuration button on
the display and to increment the numbers, press the right configuration
button. Set the numbers between –999 and 9999. The sum of the 4 mA
point and the span must not exceed 9999.
11. To store the information, press both configuration buttons simultane ously
for two seconds. The LCD meter is now configured.
Replace the Cover 12. Make sure the rubb er gasket is seated properly, replace the transparent

Square root with five-second filter
Square root function only relatesto the digital display.
The bargraph output remains linear with the current signal.
Square root response
Thedigital display will be proportional to the square root of the input curr entwher e 4 mA=0
and 20 mA=1.0, scaled per the calibrationprocedure. The transition point from linear to
square root is at 25% of full scale flow.
Filter response operatesupon “present input” and “input received in the previous fivesecond
interval”in the following manner:
Display= (0.75 3previous input) + (0.25 3present input)
Thisrelationship is maintained provided that the previous reading minus the present readingis
less than 25% of full scale.
