Note:
[1] The accuracy parameters are acquired via calibration under 25℃ after 1-hour warm-up.
[2] The maximum time required for the output to change accordingly after receiving the APPLy and SOURce commands.
[3] The variation of the output within 8 hours after 30-minute warm-up when the load circuit and environment temperature are constant.
