Flow Sensor Calibration
Use this menu to change the calibration settings (K-factor, offset and low flow
cutoff ) for the selected Flow Meter Type�
1� Navigate to SETUP > ADVANCED SETUP > SENSOR INPUTS�
2� Press UP/DOWN to scroll to FLOW SENSOR CAL, then press ENTEO�
3� Scroll to and edit each option, as necessary� The options include:
Option
K-FACTOR
OFFSET
LOW FLOW CUTOFF
MULTI-POINT TABLE
100-Point Linearization
The FC-5000 Flow Computer can be set up to linearize the output from an eligible
flow meter� The calibration data for a particular flow meter are included when the
meter, calibration and FC-5000 unit are ordered from the factory� The calibration
data is represented by either:
• Curve-fitted FREQUENCY/VISCOSITY (f/v) vs K-FACTOR (KFct) or
• FREQUENCY (f: Hz) vs K-FACTOR (KFct),
To manipulate or enter the linearization parameters:

3� Press UP/DOWN to scroll to MULTI-POINT TABLE, then press ENTEO�
4� For each calibration point, press F2 (which represents either f/v or frequency) to
enter or edit the corresponding value, then press F3 (kFct) to enter or edit the
K-factor value�
5� On the numeric entry screens, enter the value and press ENTEO to save the
value and return to the previous screen�
