III. Power set value
(Specification according to „1999 SCPI Command reference“:19 Source Subsystem)
For electronic loads applies:
• Specific commands only for electronic loads are supported since firmware 3.01 and up.
• the HIGH set value always has to be greater than the LOW set value, else an error is generated. The commands HIGH
and LOW are only valid for Level A/B operation and will generate an error in different level control modes.
• Querying and setting of set values are always dedicated to the currently selected „Level Control“. That is, if Level A is ac-
tive, the set value sent with POW is set for Level A etc. Else the set value is ignored and an error is generated. The control
mode has to be selected before the device is set into remote operation mode. The other set values, not belonging to the
preselected mode, can not be set anymore and have to be preset. Thus, for continuous remote control of the device, we
recommend to set the option „Keep set values“ in the setup menu to „no“, hence the set values are reset to default values
when switching „Mode“.

IV. Internal resistance set value
(Specification according to „1999 SCPI Command reference“:19 Source Subsystem)
For electronic loads applies:
• Specific commands only for electronic loads are supported since firmware 3.01 and up.
• the HIGH set value always has to be greater than the LOW set value, else an error is generated. The commands HIGH
and LOW are only valid for Level A/B operation and will generate an error in different level control modes.
• Query and setting of set values are always dedicated to the currently selected „Level Control“. That is, if Level A is active
and mode CR is preselected, the set value sent with RES is set for Level A etc. Else the set value is ignored and an error is
generated. The control mode has to be selected before the device is set into remote operation mode. The other set values,
not belonging to the preselected mode, can not be set anymore and have to be preset. Thus, for continuous remote control
of the device, we recommend to set the option „Keep set values“ in the setup menu to „no“, hence the set values are reset
to default values when switching „Mode“.
For electronic loads applies: Resistance range 1 is the smaller one of the two resistance ranges
