[2] This instrument has potentially dangerous 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 the chassis ground or output LO, otherwise the instrument will be damaged.
