InP
View or change the filter (set F), jitter (set J), enable
reed mode. Use the filter setting if the display is jumping
excessively due to flow conditions. Use the jitter setting to
enter a time delay to handle start up conditions. Jitter units
are seconds.
Protected Features
To enter the protected features use the left/right arrow
keys to navigate to the Pcode tab, found in the secondary
menu. Press the enter key and then enter the passcode. The
protected menu, shown below, will now be displayed. The
tabs have the following functions:
Set CD
Enter a user created numerical passcode.
Lock
Lock menu functions to prevent unauthorized
changes.
E/D R
Disable or enable the total volume reset function.
PCNT
Keeps a running tally of the number of times the
passcode has been used.
OutP
Enters the menu where the default output functions are
selected.
The P/A tab changes the function of the outputs. Default
is scaled pulse out for both outputs. Either output can be
changed to alarm high or alarm low. If alarm options are
selected menu tabs for setting the alarms will be displayed
on the main menu (alarm 1) or the secondary menu (alarm
2) If the alarm options are selected a Set H (hysteresis) tab
is available. The hysteresis entry is a % value. The value
defines the % change required for a change in alarm state to
occur.
The factory setting will show Set P2 which allows one to
view or change the volume of flow totalized per pulse sent to
pulse out 2. The units for Set P2 follow the units selected for
the rate display. If P2 is selected as an alarm the menus will
change to Set A2 and a Set H (hysteresis) tab is available.
The hysteresis entry is a % value. The value defines the %
change required for a change in alarm state to occur.
Set 4 input the flow rate at which 4 mA (min) output is de
-
sired.
ADJ L allows the adjustment of the 4 mA and 20 mA values
so that one can tune performance of the RTI2 to match the
installed system values. The adjustment units range for
0-32? Positive values adjust the setting incrementally larger
and negative values adjust the setting incrementally lower.
