Max Flow
The [Max Flow] menu cell stores the maximum range for the flow rate output (Vfo). It can be a positive
or negative value. Enter the data using the flow rate units you selected. This entry also spans the
unsigned flow variable (Vfab).
To enter the Max. Flow Range setting:
To activate numeric entry press the <Right Arrow>.
Use PC numeric keys or KeyPad to enter the maximum flow rate (100% of range).
To store the data press <ENTER>.
Min Flow
The [Min Flow] menu cell stores the minimum range for the flow rate output (Vfo). It can be a positive or
negative value (to reflect bi-directional flow). However, the minimum span for the unsigned flow (Vfab)
is always zero. Enter the data using the flow rate units you selected.
To enter the Min. Flow Range setting:
Activate numeric entry by pressing the <Right Arrow>.
Use PC numeric keys or KeyPad to enter the minimum flow rate (0% of range).
To store data press <ENTER>.
Max Vs m/s
The [Max Vs m/s] menu cell stores the maximum range for the sonic velocity output. The sonic velocity
(Vs) appears on the Stripchart display and can drive any analog output or the alarm relay. The [Max Vs
m/s] menu cell restricts this parameter to a maximum range of 2100 m/sec.
To set the maximum Vs output range:
To activate numeric entry press the <Right Arrow>.
Use PC numeric keys or KeyPad to enter the 100% range for the Vs output.
To store data press <ENTER>.
Min Vs m/s
The [Min Vs m/s] menu cell stores the minimum range value for the sonic velocity output. The sonic
velocity (Vs) can be displayed on the Stripchart and drive any analog output or the alarm relay. The [Min
Vs m/s] menu cell restricts this parameter to a minimum range of 400 m/sec.
To set the minimum Vs output range:
To activate numeric entry press the <Right Arrow>.
Use PC numeric keys or KeyPad to enter the 0% range for the Vs output.
To store data press <ENTER>.
