Operation
This section of the manual describes the basic operation of the unit. Configuration of the
parameters such as duct area, analog output range, correction factors, meter
identification or tags, etc. are covered elsewhere.
When the unit powers ON, various start up screens display the progress of the meter's
start up initialization before finally displaying the Run Mode display. The default Run
Mode display will show the meter's Tag Name and the Flow. The Run Mode display can
be configured to display other meter variables
(see section
below).
If the cover is removed, as shown in the picture, the optional keypad is accessible to
view/change the flow meter's parameters. The Keypad/LCD are shown here with the
flow body on the bottom and power/signal conduit ports on the top left and right. The
display will mount on any 90 ° angle within the enclosure. Local user input is done by
pressing the center of the keys on the membrane keypad. Kurz Instruments,
recommends using a pencil eraser. The P, D, L, E, and H keys provide the primary
navigation functions of the onboard menu system. The following sections describe this
