CHAPTER 3 - OPERATION FLUID COMPONENTS INTL
3. Operation
Alert:
Introduction
The instrument has been configured and calibrated to customer specifications. Each instrument contains distinct
operating limits and units of measurement. This chapter will show how to determine and manipulate the
configuration of the instrument.
Start Up
Verify the wiring before applying power. Verify the correct power connections have been made to the flow
transmitter. If the instrument does not have a display, plug in an FC88 Hand Held Communication unit or other
compatible communication device into P1 of the customer connection board.
1. Apply power.
2. When operating power is applied to the instrument the following messages will be displayed:
The flow transmitter contains electrostatic discharge (ESD) sensitive devices. Use standard ESD
precautions when handling the flow transmitter. See Chapter 2, Installation for ESD details.
"FCI ST98",
"Initialization!",
"Heater On!"
3. Wait 5 minutes for the instrument to warm-up and stabilize.
4. The instrument automatically enters the flow metering mode. The instrument's display (if present), and /or
the FC88 display will show the normal operation.
Note: If the FC88 does not display the monitored results properly, press [P] to re-configure the FC88 to the
operation of the ST98.
The flow meter displays an output signal that is representative of the calculated current process media flow.
If the display does not appear, or is out-of-range for the expected values, turn the power off and proceed to
Chapter 5 -Troubleshooting.
Using an FC88 Communicator
An FC88 is a hand held communicator that is plugged into the flow meter which controls the various functions of
the ST98. Plug in the FC88 to P1 of the customer connection board. See Figure 2-4 for details.
This instrument is convenient, compact, and obtains its operating power from the flow transmitter. It provides a
keypad for operator input and a display for system output.
Menu Control and Organization
Most entries require at least two key strokes; a letter and the [ENTER] key, or one or more numbers and the
[ENTER] key. All user entries begin at the Input Mode?< prompt except when the instrument is in the Main
Function Mode (just press the letter and [ENTER] to make an entry).
Doc. No. 06EN003291 Rev. A 3 - 1 Model ST98 Flow Meter
FLUID COMPONENTS INTL CHAPTER 3 - OPERATION
A user entry is indicated by brackets [ ] being placed around the entry. Y/N refers to Yes (Y), save or change
parameter or No (N) do not save or change parameter unless otherwise specified.
Backspaces are made using the backspace [BKSP] key.
Some entries are case sensitive between numbers and letters. Be sure the SHIFT key is pressed to indicate the
correct case. A square after the prompt caret indicates the FC88 is in lower case. A slightly raised rectangle in the
same spot indicates the FC88 is in the upper case.
It is recommended that the FC88 be plugged into the instrument before power is applied. If the FC88 is plugged in
while the instrument power is on and the FC88 does not respond, press [ENTER], if there is no response press [P],
if there is still no response Press [N].
Note: Some entries require a pass code (942) to continue programming the instrument. The instrument will
prompt the user when this is necessary. Do not change any parameters that require this code unless there
is an absolute understanding of the instrument's operation. Incorrect changes can cause an inaccurate or
a non-operational instrument. The figures in the "Delta "R" Table would need to be re-input.
The user can not exit some routines unless all entries are completed or the power is recycled.

Detailed Menu Description
This section describes the menu of commands. The commands are listed in alphabetical order with no order of
priority.
Note: Menu Commands are initiated by pressing the appropriate character key followed by the ENTER key.
COMMAND:
A. Analog Input
Summary:
Permits the user to display the Analog To Digital (A/D number) of the eight analog input channels. The A/D
number has a span of 0-4096 counts which is proportional to 0-4 V at the input to the A/D converter. Channels 0
through 3 receive a signal voltage that has been amplified by a factor of nine. Channels 4 through 7 are not
amplified.
These numbers can help a technician determine the cause of a problem with the installation or operation of the
flowmeter. FCI recommends making a note of these readings.
Description:
When command [A] [ENTER] is pressed, the instrument will respond by displaying the signal for Channel 0.
Continually pressing the [ENTER] key displays the rest of the channels and will rotate back to channel 0 following
the Channel 7 selection. This command is useful in trouble shooting incorrectly wired instruments and open flow
elements. This is a view only selection, the user has no other input commands.
Channel Signal Name
Number
0 ACT_SEN - REF_SEN Raw Delta-R x Gain (»9) Raw flow signal with a gain of 9, used for high flow rate.
1 -8 Volt Supply Monitor Check for -8 Volt Supply limits.
2 Sensed mA Output Load Monitor Used in calculating the output load in ohms.
3 +20 Volt Supply Monitor Check for +20 Volt Supply limits.
4 ACT_SEN - REF_SEN Raw Delta-R Raw flow signal with gain of 1, used for lower flow rate.
5 HTR_SEN - GND Sensed Heater Voltage Check the condition of the heater.
6 Circuit Board Temperature Monitor Check for Circuit Board Temperature limits.
7 REF_SEN - GND_SEN Sensed Ref-R Used to measure the reference sensor for process temp.
Purpose and Symptom
Example:
Pressing [A] [Enter] displays “Ch(0): xxxx”
[Enter] displays “Ch(1): xxxx”
[Enter] displays “Ch(2): xxxx”
[Enter] displays “Ch(3): xxxx”
[Enter] displays “Ch(4): xxxx”
[Enter] displays “Ch(5): xxxx”
[Enter] displays “Ch(6): xxxx”
[Enter] displays “Ch(7): xxxx”
[Enter] displays “Ch(0): xxxx”
Note:

Pressing [Q] [ENTER] at any time will exit this menu item and display “Input mode ?<”.
CHAPTER 3 - OPERATION FLUID COMPONENTS INTL
COMMAND:
B. Sensor Balance
Summary:
Permits the instrument's flow element to be balanced or rebalanced. A passcode must be entered. This function
has already been performed at the factory. This function should only be performed if there is a new flow element
installed or a re-calibration is necessary.
Description:
For the instrument to function properly, the flow element and electronics need to be balanced. Balancing means
that at the same temperature, the RTD's in the flow element should be at the same resistance. Due to physical
differences in the RTD's, the current needs to be adjusted for one of the RTD's so that they will both have the same
voltage. The differential should be as close to zero as possible. A passcode is necessary to enable this command.
The instrument will either balance itself or it can be done manually.
Note:
Use M (Manual) command when the circuit board or flow element has been replaced and where the
balance value representing the digitized current used for balancing has been written down.
If the Heater was ON prior to sensor balancing, be sure to turn the Heater back ON after the RTD's have
been balanced.
Example:
Pressing [B] [ENTER] will display “Enter Code #”
Press in the passcode [ENTER]. “Enter temp. #” will be displayed.
After the temperature is entered, “Auto or Manual?” and “Enter A or M<” are displayed.
Pressing [A] [ENTER] will display “xxx xxxx Balancing”. Then “Balanced!” will appear on line 1 and
“Saved! xxx” will appear on line 2.
If [M] [ENTER] is pressed instead of [A] [ENTER], the prompt “Enter Balance #” will be displayed. Once
the balance value [xxx] is entered, the balanced value entered appears on line 1 and “Saved!” is displayed on
line 2. After a couple of seconds "Saved! xxx" will be displayed on line 1 and "Input mode?<" will be
displayed on line 2. (Typical Balance values are; 234-237. Factory Balance # is on in the Delta R Table.)
COMMAND:
C. Calibrate Display
Summary:
Displays A/D Delta-R and Ref-R. Data values are useful for calibration. The instrument is calibrated at the
factory. This function does not need to be performed unless the instrument has been repaired or needs to be recalibrated.
Description:
The flow element RTD's need to be interpreted by the electronics as a function of flow-rate. This is done by
recording the raw signal A/D values at certain flow points and then curve-fitting the points using an equation to
linearize the output at the calibrated flow-rate. This command makes it possible to view both the raw A/D Delta-R
value, which is the difference between the Active and Reference RTD, and the Ref-R value, which is for the
Reference RTD. This is a view only selection, the user has no other input commands.
Example:
Pressing [C] [ENTER] will display “d= xxxx R= xxxx”. The display is updated continuously.
Note:
Doc. No. 06EN003291 Rev. A 3 - 5 Model ST98 Flow Meter

COMMAND:
K. Constants Setup
Summary:
Permits the instrument to be placed in setup mode. A passcode must be entered.
Description:
In order for the instrument to function properly, certain constant values and curve fitting parameters must be
supplied to be able to compute a verifiable flow rate for display. This command consists of four sections and is
password protected. Section (1) is available whenever default constant values need to be reloaded into the
EEPROM (the default data is automatically loaded at boot-up if a new or “cleared” EEPROM is detected). Section
(2) consists of selecting the best curve fit equation in order to linearize the input signal. The two Curve Fit
selections are: 0 = 2nd order polynomial and 2 = two 2nd order polynomials. Section (3) consists of making
available the temperature compensation factors for modification. (Section 4) allows for the maximum flow and
minimum flow parameters to be modified along with the standard density of the medium of calibration.
Example:
Pressing [K] [Enter] will display “Enter Code #”. Press in the passcode. Pressing [Enter] will display
“Defaults? <“. Pressing ‘Y’ [Enter] will setup the required initial values, pressing an ‘N’ or [Enter] will skip
to the next prompt , “Curve Fit = x”, “Change it ?<“. Pressing a ‘Y’ will display “0=Poly, 1=Log” on first

COMMAND:
L. Calibrate Outputs
Summary:
Permits user to calibrate the outputs - 4 mA level, 20 mA level and heater current. A passcode must be entered.
The instrument is calibrated at the factory. This command does not need to be done unless the instrument needs a
re-calibration.
Description:
In order for the user to calibrate the output currents, a digital-to-analog converter (DAC) is set to the correct values
so that on power-up, all the currents are reset properly each time. This is accomplished by monitoring the output
currents while adjusting input to the DAC until the correct output values are reached. Both course and fine
adjustment controls are available for calibration.

FLUID COMPONENTS INTL CHAPTER 3 - OPERATION
Example:
Pressing [L] [ENTER] will display “Enter Code #”. Press in the passcode. Press [ENTER]. "L, U, H, Q
(quit) or D (done)> will be displayed. "L" is for the 4 mA adjustment, "U" is for the 20 mA adjustment, ‘H’ is
for the heater current adjustment, "Q" is for exiting the menu at any time, and "D" is for exiting the menu
when the user is finished entering parameters. After making a selection, “[ENTER] to save” is displayed on
line 1, and “(U)up (P)down” is displayed on line 2. If [ENTER] is pressed, “L, U, H or D (Done)>” is
displayed. If [U] or [P] is pressed, “(F)fast/slow” is displayed on line 1 and “DAC: xxxxx” is displayed on
line 2, where ‘xxxxx’ is an increasing or decreasing DAC count. Pressing [U] or [P] will increase or decrease
the DAC count in the fast mode. Repeated pressing of [U] or [P] in the slow mode will increase or decrease
the DAC count in increments. To change to from fast action to slow action, press the [F] key - repeated key
presses will toggle from fast to slow to fast etc. To accept the DAC value for the selected output current, press
[ENTER]. When all outputs have been calibrated, press [D] (done) - the final DAC count values will be
displayed and a Reset command will be invoked.
Note: ADJUSTMENT of the HEATER will affect the CALIBRATION. Notify FCI Customer Service
for assistance. It is necessary to use precision instruments to perform this calibration.
Pressing [Q] [ENTER] at any time will exit this menu item and display "Input mode?<.
COMMAND:
M. Min/Max A/D Limits
Summary:
Permits minimum and maximum limits to be imposed on the A/D output data when calculating flow rate. A
passcode must be entered.
Description:
Depending on the raw A/D input, there may be instances when the linearization of the data produces what is
known as a ‘fishhook’ at either end of the flow rate spectrum. This effect may make the displayed flow to appear
increasing or decreasing opposite to the actual flow rate. The correct selection of constraint values will eliminate
the undesired effect.
Example:
Pressing [M] [ENTER] will display “Enter Code #”
Press in the passcode. Press [Enter] “Max A/D: xxxx” and “Change it ?<” will be displayed. If [Y]
[ENTER] is pressed, “Enter Max A/D #” will be displayed. Entering new the maximum A/D calibrated will
remove the high end ‘fishhook’. After the value is entered or [N] [ENTER] is pressed, “Min A/D: xxxx” and
“Change it ?<” will be displayed. If [Y] [ENTER] is pressed, “Enter Min A/D #” will be displayed.
Entering the new minimum A/D number calibrated will remove the low end ‘fishhook’.
Note:
Pressing Q [ENTER] at any time will exit this menu item and display "Input mode?<".
COMMAND:
N. Software Reset
Summary:
Permits the instrument to be initialized without removing power.
Description:
Sometimes it becomes necessary to initialize the instrument. (i.e. when entering new constants, troubleshooting, or
when power interruption is not practical.)
Example:
Pressing [N] [ENTER] will display "Restart - Wait!" followed by the initialization display: "FCI ST98",
"Initialization!", "Heater ON!", "Version x.xx" and "Scale = 1.00000".
Finally, "Input mode<", is displayed.

COMMAND:
O. Select Sensor Heater Current
Summary:
Permits the user to select the correct flow element heater current. A passcode must be entered.
Description:
The user must select the correct heater current for the flow element in use. After entering the Passcode, the current
value is displayed followed by "Change it?". If [N] [ENTER] is pressed, "Input mode?<" will be displayed, if [Y]
[ENTER] is pressed, "2 = 90mA LO#" followed by "3 = 75mA LO", followed by "4 = 90mA MD" followed by
"5 = 75mA MD" are displayed. After a choice is made, the heater will be turned ON and "Input mode?<" will be
displayed.
If a display with LO is chosen, software flags are set to inform the user if temperature values are over range (below
-50 or above 350 °F). If a display with MD is chosen, the higher temperature range software flags set.
The "LO" and "MD" designation refers to the temperature range of the sensing element. "LO" is the standard
