Model ST98 Flow Meter
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
range (-50 to 350°F). "MD" is the medium range (-100 to 500°F). "MD" is not available with early production
units. The "LO" and "MD" selections set up the proper over temperature and under temperature limits so the
temperature error message indicates correctly.
Example:
Pressing [O] [Enter] - Refer to the description.
Note:
If the FC88 is displaying "4 = 90mA MD" and "5 = 75mA MD" and the user needs to see the value for 2
or 3, press [ENTER]. The values of 2 and 3 will be re-displayed for a few seconds.
Pressing [Q] [ENTER] at any time will exit this menu item and display "Input mode?<".
COMMAND:
P. Re-configure the FC88 Unit
Summary:
Permits the hand-held FC88 unit to be reset without having to manually program the FC88.
Description:
Sometimes it becomes necessary to re-initialize the hand-held unit due to inadvertent keystroke entries or if the
FC88 had been used on another instrument. (i.e. FlexMasster.)
Example:
Pressing [P] [ENTER] will display “FC88 Reset”. After a few seconds delay “Input mode ?<“ will be
displayed.
Note:
If the FC88 has been used on a device using 80 characters (four line display), the character '-' will be
displayed instead of ‘P’ until the FC88 has been reset to use 32 characters (two line display).
