Range - Lets you select from four overlapping resistance ranges. The lower ranges provide better resolution at low
resistance settings. Alternatively, you can use the knob or press Enter to toggle between the ranges in this field. See
Programming Ranges.
Current Limit - The current limit is fixed at the specified setting.
When changing ranges, the load input will be turned off, then back on again.
Refer to Constant current mode for descriptions of the Slew rate, Enable short, Track and Sense controls.
Constant power mode
In this mode, the load will maintain the input power at the specified programmed power level. Note that the load
has an independent power limit loop that regulates the input power at the limit setting - either 250 W (EL33133A),
350 W (EL34143A), or 300 W (EL34243A), with an over-range of 10%.
Power - Lets you enter a power value with the numeric keys. Press Enter to enter the value. You can also use the
knob to adjust the value in this field.
Range - Sets the power range. Lets you select from three power ranges. The value that you enter must be the
highest value in Watts that you expect to input. Alternatively, you can use the knob or press Enter to toggle between
the ranges in this field. See Programming Ranges.
Refer to Constant current mode for descriptions of the Slew rate, Enable short, Track and Sense controls.
From the remote interface:
To specify the load operating mode:
FUNC VOLT, (@1)
FUNC CURR, (@1)
FUNC RES, (@1)
FUNC POW, (@1)
To set the voltage to 10 V, the current to 5 A, the resistance to 100 Ω, and power to 50 W:
VOLT 10, (@1)
CURR 5, (@1)
RES 100, (@1)
POW 50, (@1)
