RS232 / FC88
Menu Control and Organization
Most entries require at least two key strokes; a Capital 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 desired
function letter and [ENTER] to make an entry).
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 still no response Press [N] or cycle the power.
Note: The Zero and Span may be changed from the original calibration, provided the new values are within the original calibrated
range. i.e. If the original calibration was 1 to 100 SCFM (4-20mA), the new zero (4mA) must be equal to or greater than 1
SCFM, the new span (20mA) must be equal to or less than 100 SCFM.
Some entries require a Factory pass code. If this occurs contact FCI Field Service 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. The user can not exit some routines unless all entries are completed or the power is
recycled.
The top level of the menu is shown in Appendix B - Table 5. Enter the large letter in the tables below to activate a command. The user
may exit a command at any time entering “Q” [ENTER] in the menus: D, K, V, W, or Z.
Units
Select E=English M=Metric
Select 0= SFPS 5 = SMPS
or 1 = SCFM 6 = NCMH
or 2 = SCFH 7 = NCMM
or 3 = LBS/H 8 = KG/H
or 4 = GPM 9 = LPM
For Volumetric or Mass Flow
Select R = Round pipe or duct
or S = Square duct
Set Diameter or Wide X High (in inches or mm)
Set CMaxflow = Maximum flow rate (span)
Set CMinflow = Minimum flow rate (zero)
Table 2. “Z” Flow Units Set-Up and Scaling
Note: Changing units requires rescaling the unit (set new zero and span).
