Page 19: Operating And Safety Precautions
– Wear a heel strap when working in an area with a conductive floor. – Ground yourself before you clean, inspect, or make a connection to the U7227A/C/F. You can, for example, grasp the grounded outer shell of the analyzer test port or cable connector briefly. -
Page 20: Connector Care
– Gage connectors periodically. This not only provides assurance of proper mechanical tolerances, and thus connector performance, but can also indicate situations where the potential for damage to another connector may exist. The U7227A/C/F can be damaged if excessive torque is applied to the CAUTION connectors. -
Page 21: Cable Handling
Cable handling Because excessive bending of the cable may damage the cable over time and will affect the performance of the U7227A/C/F, the minimum bend radius of the cable is 100 mm. Excessive bending could result in internal damage caused by compression. -
