:LIST 2， 3A,2,1A,0.1A/uS,5S,2A,0.1A/uS ,5S,3 20 21 :LIST :RCL:LIST Output all steps in order 1-7 This command means CC range 3A, LIST step is 2 steps; the current of the first step is no 1A and the slope is 0.1A/uS; the time is 5s; the current of the second step is 2A, the slope is 0.1A/uS, the time is 5s. Repeatedly run 3 times and saved in LIST 2. Recall/query the LIST unit :RCL:LIST 2 Recall the query unit before query, or an Recall LIST 2 unknown condition occurs. :RCL:LIST？ >3A,2,1A,0.
:OCP 10V,5S,3A, 0.1A,0.1A,0.2S,2A,2V,1.5A,0.9 A,5 22 :OCP Output all steps in OCP mode This command means: VON voltage is 10V, VON delays 5s, current range is 3A. Initial current is 0.1A, stepping current 0.1A, stepping delay 0.2s, cutoff current 2A, OCP voltage 2V, max overcurrent 1.5A and min 0.9A, which save in LIST 5. :RCL:OCP 2 23 :RCL:OCP 1-10 Recall/query the OCP's unit. Recall the query unit before query and then use the query. Recall the OCP mode and save in LIST 2.
:OPP 10V,5S,5A, 0.1W,1W,1S,12W,7V,6.5W,5.6W,5 24 :OPP Output all steps in OPP mode This command means: VON voltage is 10V, VON delay 5s, current range 5A, intial no power 0.1W, stepping power 1W, stepping delay 1s, cutoff power 12W, OPP voltage 7V, the max overpower 6.5W and min 5.6W, which save in LIST 5. :RCL:OPP 3 25 :RCL:OPP 1-10 Recall/query OPP's unit. Recall the query Recall the OPP mode and save unit before query and then use the query. in LIST 3. :RCL:OPP？ >10V,5S,5A, 0.1W,1W,1S,12W,7V,6.
:BATT 2,30A,7A, 35V,11AH,50S This command means: setting the battery range 30A, Output all steps according to the battery discharge current 7A, no mode discharge cutoff voltage 35V, discharge cutoff capacity 11AH, and discharge time 50s, which save in LIST 2. 26 :BATTery :BATT 27 :RCL:BATTery :RCL:BATT 28 :BATTery:TIM Query the time in the battery mode no 29 :BATTery:CAP Query the capacity in battery mode no Recall/query the battery unit.
Note: 1. The unit voltage of all commands is V, current A, the current slope A/uS, the resistance OHM, power W, time s, capacity AH and percentage %. 2. All commands can be abbreviated in SCPI format, for example, DYNamic? and :DYN? are the same command.
