[1] Accuracy calculation example: For testing the accuracy of a 6V range with a 1V output, the tolerance is
[2] All channel outputs are electrically isolated from ground, but the outputs of channels CH1-CH4 share a common ground (LO)
[3] This instrument has potentially dangerous high voltage (±31.5 V) output to the HI / Sense HI / Guard terminals. To prevent electric shock, relevant precautions must be taken before powering on. Safety precautions. Do not connect the Guard terminal to any output, including shorting it to chassis ground or output LO, as this will damage the instrument.

[7] Output transition rate: Three modes of Fast, Normal, and Slow are available, allowing users to adjust according to load characteristics to achieve appropriate setup time or stability. This feature only supports switching the output transition rate when OUTPUT is set to OFF
[8] The Fast mode may produce a large overshoot under different ranges or load conditions. For overshoot-sensitive devices, it is recommended to use normal or Slow mode. mode
