Model 237-ALG-2
2 PA-298 Rev. D / June 2013
Before each use, inspect the cable, connector, and boots for wear, cracks, or breaks. Make sure the boots
completely cover the alligator clips after making connections.
The outer shield of the triaxial connector provides protection from voltages on the center and inner shield
conductors. Make sure the outer shell is always connected to earth ground or a properly grounded chassis.
Make sure both ends of the cable are properly connected before applying power. This prevents voltages from
being exposed and connections from shorting together.
Never touch or change connections when power is applied to the cable assembly. Always turn off all power and
discharge all capacitors before connecting or disconnecting the cable.
