Hardware Calibration:
The factory hardware calibration data is available as read only values and is only
performed on new modules with a special test fixture at the time of manufacture.
User Calibration of the Sensors:
If User Custom Calibration of a Sensor is desired, it can be accomplished by adjusting
the Cal Concentration, Cal Temperature or Cal Pressure values, and setting the proper
Start Bit in the appropriate User Cal Status Register.
Custom Calibration of SciPres and SciTemp Sensors is rare, and it is only
recommended on the SciCon Sensors if a much lower Cal Concentration is desired.
(12.88 mS is standard, and functions with satisfactory results.)
Factory Calibration of SciPres Sensors:
The DINPres reads and utilizes calibration data from SciPres Sensors that have been
calibrated to two points, 0 and 30 psi, or three points, 0, 54 and 6 psi depending upon the
type of stock purchased. It has also been equipped a Max Pressure Watchdog feature.
The Max Pressure Watchdog feature records in the sensor’s memory the maximum
pressure seen by the sensor while it is connected to the DINPres. The maximum
recommended pressure for the sensors is 60 psi. If this is exceeded, problems with
leakage and functionality can occur. This value is available in the appropriate register;
see the list in the next section.
Please Note: If the company Metrology Department tests the Sensors using a regulated
air source, care must be taken to avoid hi inrush pressure. Much like inrush current in
electronics, if the valve to the regulator is opened too fast, this can expose the Sensor to
higher pressures than the regulator is set for. This will be reflected in the Max Pressure
value, and may risk damage to the sensor if this is done near the 54 psi calibration point
or above.
existing factory two or three point calibration. This can be reset or cleared if desired.
