| Result | Continuity (CONT) | Insulation (ISOL) | | :--- | :--- | :--- | | | Resistance is low (e.g., < 50 Ω). | Resistance/impedance is within limits. | | HIGH / HI | Resistance too high (open circuit). | Resistance/impedance too high (open/insulated). | | LOW / LO | Resistance too low (rare). | Resistance/impedance too low (short to ground). |

The "secret sauce" of the 9240si is its .

Cycles through different configuration menus and parameter pages. AT: Flashes when the Auto-Tuning cycle is running

This guide covers the hardware setup, wiring, LED diagnostics, and configuration steps you need to get the system running.

Accepts Thermocouples (J, K, T, R, S, B, N), RTDs (Pt100, Ni120), and Linear DC signals (0-20mA, 4-20mA, 0-5V, 0-10V).

The 9240SI is valued for its accuracy and user-friendly interface, enabling technicians to quickly and reliably diagnose complex circuit issues. This tool is a portable EGSE (Electronic Ground Support Equipment) and is qualified on all Airbus family aircraft.

Once completed, the AT LED stops flashing, and the newly calculated , I , and D values are automatically locked into the permanent memory. 7. Troubleshooting and Error Codes
