(1) PIN 1: +12V API auxiliary power for APG only (maximum output current: 10mA), see
section 3.3.1.1 for detail description.
(2) PIN 2: AVO_SET_R, voltage programming for APG only that allows users to set in
“resistance form”, see section 3.3.1.1 for detail description.
(3) PIN 3: AVO_SET_C, voltage programming for APG only that allows users to set in
“current form”, see section 3.3.1.1 for detail description.
(4) PIN 4: AVO_SET_V, voltage programming for APG only that allows users to set in
“voltage form”, see section 3.3.1.1 for detail description.
(5) PIN 5: AVO_MEAS_C, voltage programming for APG only that allows users to set in
“current form”, see section 3.3.1.1 for detail description.
(6) PIN 6: AVO_MEAS_V, voltage programming for APG only that allows users to set in
“voltage form”, see 3.3.1.1 for detail description.
(7) PIN 7: N.C.
(8) PIN 8: PROG_TRIG, the external trigger signal (positive edge trigger) in program editing
mode, see section 4.1.2.2 for detail description.
(9) PIN 9: _INHIBIT, this function allows users to use the Pin 9 of ANALOG INTERFACE to
turn off the Power Supply when outputting, see section 3.3.5.4 for detail description
(10) PIN 10: DCOUT_ON, when the DC Power Supply output is ON and the voltage exceeds
VDC_R, the Pin10 (DCOUT_ON) of SYSTEM STATUS on the rear panel will turn to
HIGH. When the DC Power Supply output voltage is lower than the VDC_F setting, the
Pin10 (DCOUT_ON) of SYSTEM STATUS on the rear panel will turn to LOW. See
3.3.2.5 for detail description.
(11) PIN 11: CV_CC, this pin is HIGH when in CV mode and is LOW when in CC mode.
