Example:

“MODE:RES” – sets the Electronic Load in CR mode;

“MODE:RANG 2” – sets the Electronic Load in high range;
“MODE:RANG? CR” – queries the range for CR mode.

TRANsient

ŸTransient Programming Function

This subsystem programs the transient functions of three transient modes: CONTinous, PULSe, TOGGle. The input
levels (TLEVel) and slew rate (SLEW) are programmed from the current, resistance, power and voltage subsystems.

TRAN[:STATe]
This command enables or disables the transient or stepping function. The parameter ON | 1 enables the function and OFF
| 0 disables it.
Parameter:

ON | 1, OFF | 0

Example: “TRAN ON” – enables the transient function

DUTY
This command sets pulse duty cycle, as a percentage of the total cycle, of continuous transient mode. If the Electronic
Load is operating in another mode, the duty cycle is stored until the Load changes to continuous mode.

Parameter:

2 to 98; MIN; MAX

Unit:

%

Example: “CURR:DUTY 50” – sets a 50% duty cycle for transient current mode.

FREQ
This command sets pulse frequency of continuous transient mode in Hz. If the Electronic Load is operating in another
mode, the pulse frequency is stored until the Load changes to continuous mode.

Parameter:

0.25 to 20000; MIN; MAX

Unit:

Hz

Example:

“CURR:FREQ 1000” – sets a 1000Hz frequency for transient current mode.

SLEW
This command sets the power slew rate for the active mode. The programmed slew rate is in effect for all changes except
INP:ON or OFF. The hardware implementation selects a slew rate that is closest to the SLEW value. To determine the
actual value, use the query SLEW?.

Parameter:

0 to maximum value; MIN; MAX

Unit: Depending on mode

Example: “SLEW 6”- sets the slew rate to 6.
