Page 7: Standard And Optional Accessories
Overview Model 701944 and 701945 are high voltage probes with attenuation ratio of 100:1. The very sharp probe tip is spring loaded and minimizes the pressure to the device under measurement. It also prevents the probe from slipping on the board surface. In particular, the spring mechanism is useful when using the probe with it inclined. - Page 8 Combinations of Accessories CAUTION • Use the ground lead only for grounding connections. • Do not use any accessories other than those specified. French ATTENTION • Utilisez le fil de terre uniquement pour les connexions de mise à la terre. •...
