3302C Series Mainframe Operation Manual 4-11
LOAD ON/OFF
Purpose
：
Turn the Electronic load module input ON or OFF.
Command syntax
：
LOAD{SP}{0FF|ON}{NL}
Description
：
This command sets the Electronic load to sink current from power source.
LOAD ON the 3250A, 3310, 3330A and 3320 series Electronic load modules in the
3302C mainframe are ready to sink current from power source.
LOAD ON ; Set the load module to LOAD ON status, this load module is ready to
sink current from power source.
LOAD 0 ; Set the load module LOAD OFF.
LOAD ON VOLTAGE Setting
Purpose:
The Load ON voltage setting (Initial is 1.0V) of 3310C and 3330A series
electronic load module.
Command Syntax:
LDON{SP}{NR2}{;|NL}
Description:
The Load On voltage can be adjusted by the LDON command, the adjust range is
0.1
～
25.0 V (Res. = 0.1V), the load on voltage setting for CH A and CH B is the
same setting. The load will start to sink current if power source output voltage is
higher than load on voltage.
LDON 2.5; Set the load on voltage is 2.5V, The load will start to sink current when
power source output voltage is higher than 2.5V.
LOAD OFF VOLTAGE Setting
Purpose:
The Load OFF voltage setting (Initial is 0.5V) of 3310C and 3330A series
electronic load module.
Command Syntax:
LDOF{SP}{NR2}{;|NL}
Description:
The Load OFF voltage can be adjusted by the LDOF command, the adjust range is
0.1
～
load on voltage (Res. = 0.1V), the load off voltage setting for CH A and CH B
is the same setting. The load will stop to sink current if power source output voltage
is lower than load off voltage.
LDOF 2.0 ; Set the load off voltage is 2.0V, The load will start to sink current when
power source output voltage is lower than 2.0V.
