3302C Series Mainframe Operation Manual 4-9
RESISTANCE Level
Purpose
：
The load resistance setting in Constant Resistance mode.
Command syntax
：
CR
：
{HIGH|LOW}{SP}{NR2}{;|NL}
CR
：
{A|B}{SP}{NR2}{;|NL}
CR
：
{SP}{NR2}{;|NL}
Description:
CR
：
{HIGH|LOW}{SP}{NR2}{;|NL}
This command is used to set the LOW/HIGH load resistance level of 3310 series
electronic load module.
CR
：
{A|B}{SP}{NR2}{;|NL}
This command is used to set the load resistance for LEVEL A/B of 3250A series
electronic load module.
CR
：
{SP}{NR2}{;|NL}
This command is used to set the load resistance level of 3330A Series load
module.
Note
：
1.The load resistance data must include decimal point, otherwise this command is
unable to execute. The most effective load resistance level can be set is the
sixth digit after the decimal point.
2.The HIGH load level load resistance MUST be higher than LOW level load
resistance for proper HIGH/LOW resistance level definition, the load resistance
difference between programmed HIGH and LOW level is 10 times of resolution
at each range, the 3310 series Electronic Load will adjust and limit of the
programmed values.
If the programmed HIGH level is equal or less than LOW level, the 3310 series
load module will adjust and limit HIGH level to be higher 10 times programming
resolution of LOW level, and vice versa at the programmed LOW level is equal
or more than HIGH level.
3.If the programming load resistance level over the maximum specification at
programmed range of 3310 series load module, the full scale resistance will be
sent to the load module.
4.Please make sure range I/II command before execute the load current setting
command, otherwise the 3310 load current after programming the RANGE
command.
5.LOW|HIGH option is for 3310 series electronic load module.
6.A|B option is for 3250A series electronic load module.
7.The engineering unit for load resistance is Ohms.
8.Please refer to Appendix C for proper programming procedure of 3310 series
electronic load module.
For Example
：
CR
：
LOW 0.123 set LOW level load resistance to 0.123 OHM.
CR
：
HIGH 3.456789 set HIGH level load resistance to 3.456789 OHM.
