Mount the probe with finger tight torque initially, then apply a maximum torque of 0.56 N•m (5 in•lb). For M8x1 threads, the maximum recommended torque is 7.3 N•m (65 in•lb) rated, with 5.1 N•m (45 in•lb) recommended. Ensure thread engagement does not exceed 12 mm.\u003c\/p\u003e\u003cp\u003eMaintain a minimum bend radius of 25.4 mm (1.0 in) for the probe cable to avoid damage. When routing field wiring, follow the frequency response graphs (Figures 16 and 17) to account for signal rolloff at high frequencies over long distances.\u003c\/p\u003e\u003ch2\u003eCompatibility and Integration\u003c\/h2\u003e\u003cp\u003eThe 330903-00-03-50-02-05 is mechanically and electrically interchangeable with Bently Nevada's previous 3300 RAM probe and extension cable.
