[1] Accuracy calculation example: to test the accuracy of a 120 mV output on the 600 mV range, the tolerance is:

[2] This instrument has potentially hazardous high voltage (±210 V) output to the HI /Sense HI/Guard terminals. To prevent electric shock, relevant safety precautions must be taken before powering on. Do not connect the Guard terminal to any output, including shorting it to chassis ground or output LO, otherwise the instrument will be damaged

[3] The 3 A range supports pulse mode only; accuracy is typical.

[4] For low-current measurement, triaxial cable connection is recommended: Hi to the center conductor, Guard to the inner shield, outer shield to protective ground; LO to the center conductor, inner shield unconnected, outer shield to protective ground. The rated insulation voltage of the coaxial cable shall be no less than 250 V
