FloBoss 103/104 Instruction Manual
8-2 Calibration Revised August-2017
Note: If you are calibrating the AI on the optional I/O termination
board, select Configure > I/O > Analog Input > AI
Calibration tab.
The current reading displays under each meter input as the Freeze
Value. The FB100 uses these values in the flow calculations while
calibrating the points.
3. Click Freeze.

4. If you are calibrating a pressure input, read the following Caution,
and then isolate the pressure sensors from the process.
If you are calibrating a RTD temperature input, proceed to Step 6. If
you are calibrating the optional AI (AI Point Number B1), proceed
to Step 8.
Open the by-pass valve on the valve manifold prior to isolating the
sensor from the process, to protect the differential cell of the Dual-
Variable Sensor. This keeps one side of the differential sensor from
being subjected to high pressure while the other side has no pressure
applied. This is required when calibrating either differential or static
pressure. Refer to Figure 8-2 for the recommended sequence.
