Query Syntax
: [LOAD:]ABA?
Response Parameter: OFF|ON
Example
: ABA ON
[LOAD:]MODE
Description: This command selects the operating mode for AC/DC voltage input. The
electronic load can be programmed to operate for constant current, constant power, constant
resistance, constant voltage(DC mode only), RLC(AC mode only), RLC constant power(AC
mode only), RLC inrush current(AC mode only), Rectified(DC mode only). The query form
returns the load operating mode for AC voltage input mode.
Setting Syntax
: [LOAD:]MODE
Setting Parameter : 0 | CURR, 1 | POW, 2 | VOLT, 3 | RES
4 | RLC, 5 | RLCP, 6 | INRUSH, 7 | RECT
Query Syntax
: [LOAD:]MODE?
Response Parameter : CURR, POW, VOLT, RES, RLC, RLCPOW, INRUSH, RECT
Example
: MODE CURR
[LOAD:]SCIRcuit
Description: Activate or inactivate short-circuited simulation. (It is only operating in
CC/CP/CV/CR Mode.)
Setting Syntax
