1. The 10A range supports pulse mode only; accuracy is typical

2. For low-current measurement, it is recommended to use a triaxial cable: connect ForceHi to the center conductor, Guard to the inner shield, and the outer shield to protective ground; connect ForceLo to the center conductor, leave the inner shield unconnected, and connect the outer shield to protective ground. The rated insulation voltage of the coaxial cable must be no less than 250V.
