2.9.3 Current Limit in CV Mode
The CV Curr Limit is used to limit the maximum input current in CV mode. If the voltage is still
larger than the set level while the current limit has been reached, the load will switch to the CC mode.
Please see figure 2-13. The input will not be turned off in the CV current limit, which is different from
the software current limit.
The CV Curr Limit can be set in main menu, or via the remote command ( INPut:LIMit:CURRent
<NRf+>).

2.9.4 Current Rise Rate
The Current Rise Rate is used to set the current rise rate in CC mode. It can be set in main menu,
or via the remote command (CURRent:RISE:RATE <NRf+>).
If the current rise rate is 0.1A/us, and the current set level is 20A, then the current rise rate is
shown as below when the input is turned on:
Fig.2-14 Current Rise Rate
Note: The Current Rise Rate can be effective only in CCH and CCL, and the actual rise rate is
one tenth of the set level in CCL.
2.9.5 Current Fall Rate
The Current Fall Rate is used to set the current fall rate in CC mode. It can be set in main menu,
or via the remote command (CURRent:FALL:RATE <NRf+>).
If the current fall rate is 0.1A/us, and the current set level is 20A, then the current rise rate is
shown as below when the input is turned off:
