value is a customer-programmed constant used to offset the flow output independently of
all other sensor offset constants, including the zero process. For example, set Target Null
Value: -20%F.S
，
then when no flow through MFC/MFM
，
the reading is -20%F.S
，
with gas
flow 20%F.S through MFC/MFM
，
the reading is 0%F.S
。
Offset range is from -100%F.S
to100%F.S

3.10 Total Flow Accumulator
The Total Flow accumulator will record the amount of gas (in SCC) that has been
delivered by CS100MFC/MFM. The amount of purge will not be accumulated in the total
flow amount. For example, the total reading is 3000, means the amount of gas delivered by
MFC is 3000SCC

3.11 Alarm
The CS100 MFC/MFM will monitor and store certain abnormal conditions as
described below. These conditions can be read and reset from the RS485 interface.
Provisions will be made for masking (disabling) the alarms or warnings on an individual
basis.
Warning and Alarms:
Sensor Zero Output Out of Bounds
EEPROM Failure
Valve Coil Failure or Valve Disconnected
Temperature Out of Operating Range
After power up the LED on the top of the CS100 MFC/MFM is turned GREEN. A
