Five Measurement Strategies

The document includes torque curve diagrams corresponding to each strategy

Peak (DD): Measurement of peak torque for direct drive tools, universal mode; Reset time can be set to filter clutch impact noise.

Static installed torque: used for retesting residual torque after assembly; Slowly turn the wrench, and the instrument automatically recognizes the installation torque at the moment when the bolt starts to rotate.

Multistage multi-level strategy: used for calibrating scenarios; Twist to the target torque → Reverse 720 ° → Twist to the target angle again; Reduce angle measurement interference, the connector is in a loose state at the end of the test, only used for laboratory testing, and cannot be used for actual assembly.

Break away strategy: used for click wrenches; Identify the torque drop slip point and record the peak torque for disengagement.

Peak (Pulse): specifically designed for pulse tools; Simultaneously measure peak torque and pulse count.

Measurement result window

Basic basic window: real-time torque, angle, pulse; Last 5 measurement records, real-time 3 σ statistical interval.

Zone Result: Overall judgment of multi tool combination testing.

Calibration and Calibration Chapter (Core Functions)

1. Tool calibration

1) Manual calibration: Sensor measurement tool outputs, collects multiple sets of data, compares controller readings, calculates correction factors (cal torque/scale factor), generates backup tool archives; 2) Automatic calibration: The Power Focus/PowerMACS controller is controlled through RS232/Ethernet to automatically perform batch tightening, and the Multistage strategy completes calibration fully automatically without manual operation.

Different controllers (PF series/PowerMACS/DS-DL/third-party controllers) have different calibration calculation formulas and interfaces.

2. Sensor calibration Deadweight weight calibration

Apply standard torque to the sensor using a standard weight arm device; At least 3 sets of loading unloading points shall be collected to calculate the sensitivity mV/V, which can be directly written into the Atlas sensor with memory chip; Simultaneously perform linearity verification; Generate sensor calibration report.

3. ACTA host calibration

It must be carried out in a certified laboratory once a year and cannot be completed locally by the user; Expired device pop-up reminder.

Collaborate with Torque Supervisor software

PC Torque Supervisor edits the test task sequence and issues ACTA via USB/RS232/Ethernet; The distribution will clear the original tools and measurement data on this machine, and it is necessary to backup them in advance.

ACTA executes the entire set of tests offline; After completion, send all results back to the PC software for data analysis and output report.

Provide a complete workflow diagram for the document; Define a mapping comparison table between Torque Supervisor testing methods and ACTA internal measurement strategies.
