Area Cross-sectional area of pipe or duct
Diameter Inner diameter of pipe
Temp. Unit Unit of temperature
Tcal Add A value that is added to measured temperature (default is 0)
Tcal Mult A value that is multiplied by the measured temperature (default is 1)
Relay 1 Current status of Relay 1, energized or de-energized
Above, Below, See Chapter 4 Relays, for the explanation
Inside or Outside
H: Hysteresis value (in flow rate units such as 50 SCFM etc.)
D: Delay in seconds
Relay 2 Current status of Relay 2, energized or de-energized
Port 1 Channel 1 output signal
Mode Current (4 - 20 mA) or Volts (0 - 5, 0 - 10, etc.) output
F.S. Full Scale: 100% of flow rate
Zero 0.00 for zero based and Min flow for non-zero based
Port 2 Channel 2 output signal
Corr1 through Corr4 Correction Factors: Default is Corr 2 = 1 and Corr1, 3, 4 = 0
(Flow) = Corr1 + Corr2(Flow) + Corr3(Flow)2 + Corr4(Flow)3
Menu 5.8 Menu Function
dR gain Digital representation of A/D# for DR value - derived
during front-end set-up: R = dR Gain X A/D# + dR Off
R gain Digital representation of A/D# for REF RTD value - derived
during front-end setup: REF R = R Gain X A/D# + R Off
dR Off Offset value of equation: R = dR Gain X A/D# + dR Off
Ref off Offset/constant value for REF RTD derived
during front-end set-up: REF R = R Gain X A/D/# + R Off
Offset 1 Offset for equation: REF R = R Gain X A/D# + R Off
Slope 1 Slope for equation: D/A# = current X Slope 1 + Off 1.
Corresponding to current or voltage output
Offset 2 Offset for equation: REF R = R Gain X A/D# + R Off
