D. DIAGNOSTIC Menu Function.
Single Poly Fit The polynomial equation used by the electronics to interpret the signal from
the flow element.
Two Poly Fit The equation used by the electronics to interpret the signal from the flow element.
Brkpt This is the break point (Delta-R) between the two poly fit equations.
Poly Segment 1 The first group of polynomial equations used to detect flow.
Poly Segment 2 The second group of polynomial equations used to detect flow.
C1 - C5 Calibration equation coefficients.
Balance A number used to balance or match the active and reference RTD's when the heater
is off.
Outz An A/D number representing 4 mA. This is set during calibration.
Outf An A/D number representing 20 mA. This is set during calibration.
Heater I An A/D number representing heater current. This is set during calibration.
Factor This is a conversion factor that is multiplied by SFPS to convert to customer units.
Eu The ASCII code for engineering units are as follows:
Tot A 1 after the Tot indicates the Totalizer is turned on. A 0 after the Tot indicates the
Totalizer is turned off.
Tottemp A 1 after the Tottemp indicates the Totalizer Temperature display is turned on.
A 0 after Tottemp indicates the Totalizer Temperature display is turned off.
Tflow This is the totalized flow in volumetric or mass units, it will change as the
instrument totalizes flow.
Rollover The place where the totalizer will roll over to zero. (1E9)
Roll cnt Counts the number of times the Totalizer has rolled over to zero.
Outmode The output mode is symbolized as follows:
Max A/D High end cut-off A/D number. Prevents false low flow readings.
Min A/D Low end cut-off A/D number. Prevents false high flow readings.
Kfactor User programmable correction factor. The corrected output equals K times
the output.
Zero An adjustment that establishes at what flow rate the flow transmitter's
output is at its minimum (4 mA, 0 VDC). 0.00 is for zero based
