This test process measures the pneumatic differential pressure between two points generated by the unit under test. The resulting pressure difference will return in the unit of measure as defined in the test point’s data.
Note: Although the unit of measure can be read from the test point’s unit of measure it is good practice to pass the Unit of Measure to the test process as a parameter to avoid confusion when synchronizing data between systems.

Definition- A test process measuring the accuracy of a torque wrench or other torquing device.
Required Parameters
- Torque – The expected torque {in Nm if the unit of measure is included}
Optional Parameters
- Direction – {CW, CCW}
- Connector – Text
Output Value & Uncertainty
Definition- A test process that measures the accuracy of hydraulic torque wrenches where hydraulic pressure is applied to the torque wrench and it applies a known torque to the nut or bolt being tightened.
This process usually is used to calibrate hydraulic torque wrenches producing a lookup sheet the operator can use to quickly look up the pressure required to correctly torque the bolt or nut.
Required Parameters
- Pressure – The hydraulic pressure applied {in Pa if the unit of measure is included}
- Torque – The expected torque output {in Nm if the unit of measure is included}
Optional Parameters
- Direction – {CW, CCW}
- Connector – Text
Output Value & Uncertainty
A test process that measures the ratio between the AC ripple & noise in RMS voltage measured on a DC signal then divided by the DC voltage level creating a ratio between the two voltages.
