4.1 Explanation of Display Prompts
(continued)
fr#
: (frequency for point #) This prompt will only appear when 20 point selected. It sets the frequency for each of
the 20 points (#). Press the
↑
key to increment each digit. Press the
←
key to step to the next digit to the left.
Press the
E
key to enter the desired frequency for point #.
faC#
: (factor for point #) This prompt will only appear when 20 point selected. It sets the factor for each of the 20
points (#). Press the
↑
key to increment each digit. Press the
←
key to step to the next digit to the left. Press
the
E
key to enter the desired factor for point #.
NOTE:
The display will advance to the next point (Fr#) after each entry of the Fr & Fac until all 20 points are com-
plete. entering a 0 in the Fr or fac setting will advance the display to the next menu prompt (tdec).
tdeC
: (totalizer decimal) Sets the decimal location for the totalizer. The totalizer decimal is not a dummy decimal
and will scale the totalizer display accordingly. (i.e. if the tdec is set in the tenths position (1234567.8), 100 will be
displayed as 100.0). The location of the decimal point allows for greater resolution of both the totalizer display
and the pulse output. The pulse output advances at a rate dependent on the least signifi cant digit of the total-
izer. The totalizer decimal location is restricted to a maximum of 4 places (1234.5678). However, the number
of totalizer decimal locations allowable is reduced with each decimal place added to the factor decimal. Press
the
←
key to move the decimal. Press the
E
key to enter the displayed decimal location.
Note:
The selection of the factor decimal point limits the available selections for the number of decimal
points available for the totalizer. This is automatic. Enter your selection of the Factor’s decimal point
before entering the totalizer decimal point to assure the proper selection of the totalizer decimal
point has been made.
tot desC
: (totalizer descriptor) This allows you to illuminate one of the available descriptors on the display (STD:
GAL, LIT, FT3, M3 or "blank"; "D" option: GAL, BBL, MCF, M3, "blank"). Press the
↑
key to select the descrip-
tor. Press the
E
key to enter the selected descriptor.
r sCale
: (ratemeter scaling) Sets the rate readout. Choose rate per hour (
Hrs
), minutes (
nnIn
) or seconds (
seC
).
(Days will appear on units ordered with the "D" (rate per day) option.) The scale setting is shown on the main
(upper) display. Press the
↑
key to step to the desired choice. Press the
E
key to enter the displayed scale
setting.
Note:
A rate descriptor corresponding to the above choice will be illuminated on the display.
r deCloC
: (ratemeter decimal location) Sets the decimal location for the ratemeter. The ratemeter decimal is not
a dummy decimal and will scale the rate display accordingly. (i.e. if the r decloc is set in the tenths position
(123.4), 100 will be displayed as 100.0). The ratemeter decimal location is restricted to a maximum of 4 places
(.1234). However, the number of ratemeter decimal locations allowable is reduced with each decimal place
added to the factor decimal. Press the
←
key to move the decimal. Press the
E
key to enter the displayed
decimal location.
Note:
The fl ow rate indicator will fl ash “99999” if the computed fl ow rate exceeds the 99999
display capability of the indicator. Choose a new decimal point location to avoid this.
NOR#
NORMALIZING FACTOR - Normalizes (averages) the data being received. Enter a value from 0 to 9.
Higher settings provide more normalizing (averaging) for a more stable display. Derived from the equation:
(Old Data x "NOR" + New Data)
(Old Data x "NOR" + New Data)
("NOR" + 1)
delay
: (delay) Sets the amount of time (0.1 to 99.9 seconds) that the unit will "look" for valid input data. If pulses
are not detected within this "window", the rate will display 0. The display will update once every second as
long as the unit receives valid data within a second. Some internal mathematics may delay this update.
Press the
↑
key to increment each digit. Press the
←
key to step to the next digit to the left. Press the
E
key
to enter the displayed delay value.
oUt lo
: (out low) Sets the low setting for the 4-20 mA analog output. Key in the low rate value at which the unit will
output 4mA. Press the
↑
key to increment each digit. Press the
←
key to step to the next digit to the left. Press
the
E
key to enter the displayed out lo value.
