M540073-01 Rev C

VA Limit

Purpose:
To set the upper/lower limit value of threshold power (VA).
Command Syntax:
LIM:VA:{HIGH|LOW}{SP}{NR2}{;|NL}
Description:
This command is to set the upper/lower limit value of threshold power (VA). When power
(VA) is lower than this lower limit value or higher than the upper limit Value, NG indicating
light will come on to indicate “NO GOOD."

Example:
LIM:VA:LOW 0.05 ; To set the lower limit value of threshold power (VA) is 0.05 VA.
LIM:VA:HIGH 250.0 ; To set the upper limit value of threshold power(VA)is 250.0 VA.

SENSE ON/OFF

Purpose:

Set the voltage sense ON/OFF of Electronic load.
Command Syntax:
[GLOB:]SENS{SP}{0|1|OFF|ON}{NL}
Description:
Set the Vsense inputs Off or On. If Vsense is set to Off, voltage measurement is taken at
the load input terminals or automatically sensed. If Vsense is set to On, voltage is
measured at the Vsense input.

Example:
GLOB:SENS ON set all load module V-sense input to sense ON state.
SENS OFF set load module V-sense input to sense OFF state.
DUAL OFF; Disable the dual meter function, the upper 5-digit LED display is voltage meter,
the lower 5-digit LED display is current meter.

4.4.2 Query

Commands

CURRENT Level

Purpose:
The Constant Current mode's load current level query command.
Command Syntax:
CC:{HIGH|LOW}{?}{;|NL}

Description:
CURR:LOW? return the presently programmed low load current level in Constant Current
mode of the electronic load.
CURR? return the presently programmed load current level in Constant Current mode.
