This manual describes the principle of the PosiTest pull‑off adhesion tester, which uses hydraulic force to detach a coated surface and measures the adhesion strength in PSI or MPa. It includes preparation of the test substrate and adhesive, selection of test pads, and the standards used for measurement.
Detailed operating procedures are given for both the manual AT‑M model and the automatic AT‑A model, covering power‑on, pad selection, pressure application, data storage, battery charging, and troubleshooting steps such as emergency shutdown and error handling. This manual is written in Chinese.
| Measurement units | PSI or MPa |
|---|---|
| Adhesive layer thickness | 50‑100 µm |
| Maximum pressurization speed | < 1 MPa per second |
| Battery runtime (AT‑M) | ≈ 60 hours continuous |
| Battery charging time | ≈ 14 hours |
Mix the two components for at least 45 seconds to achieve a uniform mixture.
Remove any excess adhesive with a knife before the curing process.
Hold the power key and then press the EU key to force the instrument to power off.
The AT‑M battery can operate continuously for about 60 hours.
