DISPLAY 0-50.00 RATE FROM 1-10 kHz INPUT, COORDINATES OF 2 POINTS METHOD
Application: Display 0-50.00 (with two
decimal places) for 1-10 kHz input. Use
coordinates of 2 points scaling method.
Solution: Set Input to “Rate A O
nly.”
Select “coordinates of 2 points” scaling
method under Setup. This is easier than
scale and offset. Set DecPt1 to two places.
Then enter the low input and desired low
reading, and high input and desired high
reading, as shown.
DISPLAY RATE IN GPM FROM 36.67 PULSE/GALLON TURBINE FLOW METER
Application: Display rate in GPM to two
decimal places from flow meter calibrated
to 36.67 pulses/gallon.
Solution: Set Input to “Rate A Only. Un-
der Setup, select “coordinates of 2 points”
scaling method. Set DecPt1 to two places.
Then enter the low input and desired low
reading, and high input and desired high
reading, as shown. In this example, we
want to display 60.00 (GPM) from an input
of 36.67 Hz. Note that the meter’s native
rate measurements are in Hz. There will be
60 times more gallons per minute than per
second.
Rate in engineering units is displayed from measured frequency by applying an appro-
priate scale factor and setting the decimal point. The scale factor consists of a scale value
from 0.00000 to 9.99999 (fixed decimal point and settable digits) and a scale multiplier from
0.00001 to 100000 (in decade steps). When using the coordinates of 2 points method to
scale the meter, the low input and high input frequencies are entered in Hz.
• RATE A ONLY (A_OnLy) displays rate or frequency for Channel A. The latter utilizes
SCALE1, OFFSt1 and dECPt1. Channel B is not used.
• RATE A B (A__b__) displays rate or frequency for Channel A as Item #1 or for Channel
B as Item #2. The latter utilizes SCALE2, OFFSt2 and dECPt2.
• RATE A, TOTAL A (A_Atot) (Extended counter) displays Rate for Channel A as Item #1
and Total for Channel A as Item #2 since last reset. Total may count down from an offset
by entering a negative scale factor. Only used for non-linear inputs.
