Example 3 - Hydraulic Wrench calibration
For this example, we’re going to test a hydraulic/pneumatic wrench using a pressure transducer and a torque
transducer attached to the AnB modules. Our goal is to measure the torque produced by the tool at specific
pressure levels.
1. Set up a new Targets file with a series of pressure targets corresponding to the pressure levels of
interest. You likely have at least a few levels of interest across the capacity range of the tool, but if you
are interested in more data points, just add more targets. Your targets should use a very small (or even
0%) lower tolerance, to ensure the readings are captured as close to the target point as possible.
2. Enter the Targets screen settings and change the targets type to “Linked”
3. Return to the target list on the Targets screen and use the Up/Down buttons to arrange the targets by
pressure in ascending order (the list should start with the lowest pressure and end at the highest).
4. (Optional) Repeat steps 1-3 to make another Linked Targets file containing a series of increasing torque
targets that correspond to each of the pressure targets; these represent the anticipated torque output of
the tool at each given pressure target. It may be useful to have the pressure and torque targets files
opened side-by-side during this step.
5. Open a Measurement screen for the AnB module connected to the pressure transducer. Go to Mode
settings, and change the mode to Hydraulic. Enable Auto Reset, Progressive Reset, and Broadcast
Capture Trigger, then press Set to set the mode. This prepares the AnB module to sweep through a
progressive series of linked targets, and trigger captures of corresponding readings on the other AnB
module.
6. On the Measurement screen, open the Targets screen and set the AnB module’s target to the first
target of the pressure targets file. You may need to go into Targets screen settings and open the targets
file from there.
7. Ensure the Save button is toggled on. With the mode configured and initial target set, the pressure AnB
is ready to sweep through the list of linked pressure targets.
8. Open a second Measurement screen for the AnB module connected to the torque transducer.
9. Go to Mode settings on the torque AnB, and change the mode to Hydraulic. Ensure Auto Reset is
enabled. Ensure Progressive Reset is disabled. Broadcast Capture Trigger is disabled.
11. After setting the torque AnB mode, you should have two Measurement screens side-by-side, one for
pressure, one for torque. Begin sweeping through the pressure range; you should see the AnB module
smoothly capture pressure readings the moment the target pass conditions are met. You should see
corresponding torque readings simultaneously captured on the torque AnB. If you followed the optional
steps, you should also see the torque AnB step through each torque target in tandem with every
pressure reading.
