8550-3 Flow Transmitter Instructions

‡ SIGNET

Adjust the LCD contrast for best viewing.  A setting of 1 is lower contrast, 5 is higher.
Select lower contrast if the display is in warmer ambient surroundings.

Set the decimal to the best resolution for your application.  The display will automatically
scale up to this restriction.
Select *****., ****.*, ***.**, **.***   or *.****

Set the totalizer decimal to the best resolution for your application.
Select ********., *******.*, or ******.**

OFF provides the quickest output response to changes in flow.
LOW averaging  = 4 seconds, HIGH averaging = 8 seconds of input signal.
Longer averaging produces more stable display and output response.

Lock Off : No key code required to reset the resettable totalizer.
Lock On : The Key Code must be entered to reset the resettable totalizer.

Adjust the minimum and maximum current output. The display value represents the
precise current output.
Adjustment limits:
•  3.80 mA < 4.00 mA > 5.00 mA
•  19.00 mA < 20.00 mA > 21.00 mA
Use this setting to match the system output to any external device.

Active HIGH: This setting is used to turn a device (pump, valve) ON at the setpoint.
Active LOW:  This setting is used to turn a device OFF at the setpoint.

Press UP or DOWN keys to manually order any output current value from 3.6 mA to
21.00 mA to test current loop output  #1.

Press UP or DOWN keys to manually toggle the state of open collector output #1.
