Gpib Command Description - Prodigit 33501 Series Operation Manual

4-5. GPIB command description

1. Setting Command
CURR
Purpose：The load current setting in Constant Current mode.
Command syntax：CURR：{LOW|HIGH}{SP}{NR2}{NL}
Description：This command is used to set the load current level.
Note:
1. The load current data must include decimal point, otherwise this command is unable to
execute. The effective load current level can be programmed is the sixth digit after the
decimal point.
2.The HIGH load level load current MUST be higher than LOW level load current for proper
dynamic waveform definition, the load current difference between programmed HIGH and
LOW level is 10 times of resolution at each range, the 33501 Series Electronic Load will
adjust and limit of the programmed values.
If the programmed HIGH level is equal or less than LOW level, the 33501 Series load 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 loads current level over the maximum specification at programmed
range of 33501 Series load, the full-scale current will be sent to the load.
4. Please make sure range I/II command before execute the load current setting command,
otherwise the 33501 Series load will adjust to fit the load current after programming the
RANGE command.
5. LOW|HIGH option is for 33501 Series electronic load.
6. Engineering unit for load current is Amps.
For Example：
CURR：LOW 1.8 set LOW level load current to 1.8 A.
CURR：HIGH 25.123456 set HIGH level load current to 25.123456 A.
RES
Purpose：The load resistance setting in Constant Resistance mode.
Command syntax：RES：{LOW|HIGH|A|B}{SP}{NR2}{NL}
Description:
This command is used to set the LOW/HIGH load resistance level.
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 33501
Series Electronic Load will adjust and limit of the programmed values.
If the programmed HIGH level is equal or less than LOW level, the 33501 Series load 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 33501 Series load, the full-scale resistance will be sent to the load.
