RS232 / FC88
Menu Control and Organization
All user entries begin at the iput mode prompt “>”,except when the instrument is in the Main Function Mode. Most entries require at
least two key strokes; a Capital letter and the [ENTER] key, or one or more numbers and the [ENTER] key. If the unit is in the Main
Function Mode just press the desired function letter 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.
Caution: Always press “T” before unplugging the FC88. If a frozen meter display is observed, reconnect the FC88 and
wait 5 seconds for the meter to initialize. Disconnect the FC88 and confirm your meter display is varying.
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

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)
