1. Adjustment ranges remain the same whether in U.S. or Metric units; the settings
are dimensionless.
2. Each offset unit for 100 psi sensors is equal to 0.50 psig (0.0345 bar).
3. Each offset unit for 500 psi is sensors is equal to 2.0 psig (0.138 bar).
4. The standard 1-inch flow turbine should be calibrated with a flow offset of zero.
Each offset unit equals 0.0264 gpm (0.1 Lpm).
5. The “slope” for both flows should be set to 362 for 1-inch turbines. The slope
has units of Lpm/(100 turbine revolutions).
6. Setting the Flow Offset to 99 will force the flow readings to 0.1 to temporarily by-
pass a failed flow sensor or turbine until replacement is installed.
7. To calibrate pH, the passcode must be entered separately for each item, and the
pH electrode must be put in two different pH reference solutions (4.0 for Low and
10.0 for High, or 4.0 and 7.0, or 7.0 and 10.0).
8. Pressure offsets are for field personnel to easily enter minor adjustments to the
operating pressure readings without recalibrating and are used to temporarily
“dial-out” a transducer that is beginning to fail, in order to keep the machine
running until the sensor can be replaced. Adjustment of these offsets reduces the
accuracy of the readings throughout their operating range.
