This chapter describes the processes for calibrating the AI, RTD, and
Meter modules for the FB100-Series devices.
Use ROCLINK 800 software to perform initial calibration or re-
calibration, which might be required for example after you change an
orifice plate in the meter run handled by the FB103.
The calibration routines support 5-point calibration, with the three mid-
points calibrated in any order. Calibrate the low-end (or zero) reading
first, followed by the high-end (or full-scale) reading. Calibrate the three
mid-points next, if desired.
The diagnostic analog inputs for logic voltage E1, battery voltage E2,
and board/battery temperature E5 are not designed to be calibrated. The
diagnostic analog input for charge input can be resealed and calibrated.
The built-in inputs may be calibrated with the 5-point routine. The built-
in inputs are assigned to the first three analog input points:
▪
Differential pressure (for AGA3) or Meter pressure (for AGA7)
located at AI Point A1.
▪
Static pressure (for AGA3) or Auxiliary pressure (for AGA7)
located at AI Point A2.
▪
RTD temperature located at AI Point A3.
You can then calibrate the optional analog inputs on the termination
board (if you have configured the as analog inputs) using the 5 point
routine.
To perform a calibration:
1.
Start ROCLINK 800 and connect to the FB100.
2.
Select either Meter > Calibration or Configure > I/O > Analog
Input > AI Calibration tab. The Meter Calibration screen displays.
