5.6.3 Programmable Current Protection
When programmable current protection is enabled, and the programmed current limit and time delay are exceeded, the load‘s input will
be turned off.
5.7 CC Mode Examples
This example sets the current level to 0.5 A, and then reads back the actual current value.
1 "INPUT OFF" Turns off the load` s input
2 "MODE CCL" Selects the CCL mode
3 "CURR 0.5" Sets current level to 0.5 A
4 "INPUT ON" Turns on the load‘s input
5 "MEAS:CURR?" Measures the actual input current
5.8 CV Mode Examples
This example presets the trigger voltage to 5 V, and selects the external trigger source.
1 "INPUT OFF" Turns off the load`s input
2 "MODE VOLT" Selects the CV mode
3 "VOLT:TRIG 5" Presets the trigger voltage to 5V
4 "TRIG:SOUR EXT" Selects the external input as the trigger source
5 "INPUT ON" Turns on the load`s input
In this example, the input voltage will be set to 5 V when the change in the level of the external trigger signal is received.
5.9 CR Mode Examples
This example sets the current protection limit to 3 A, sets the time delay to 10 s, programs the resistance level to 10 Ω, and reads back
the computed power.
1 "INPUT OFF" Turns off the load`s input
2 "MODE CRM" Selects the CRM mode
3 "CURR:PROT: LEV 3.DEL 10" Sets the current protection limit to 3 A and current protection delay time to 10 s
4 "CURR:PROT:STAT ON" Activates the current protection
5 "RES 10" Sets resistance level to 10 Ω
6 "INPUT ON" Turns on the load‘s input
7 "MEAS:POW?" Measures the input power level
5.10 Continuous Transient Operation Example
This example sets CV transient high/low levels, the associated
times for transient rising/falling edge, high/low level times, and parameters for transient operation.
1 "INPUT OFF" Turns off the load` s input
2 "MODE CV" Selects the CV mode
3 "VOLT:LOW 0.5" Sets the transient low level to 0.5 V
4 "VOLT:HIGH 1" Sets the transient high level to 1 V
5 "TRAN:LTIM 200us" Sets transient low level time to 200 μs
6 "TRAN:HTIM 300us" Sets transient high level time to 300 μs
7 "TRAN:RTIM 10us" Sets the time for transient rising edge to 10 μs
8 "TRAN:FTIM 20us" Sets the time for transient falling edge to 20 μs
9 "TRAN:MODE CONT " Selects the continuous transient operation
10 "TRAN ON" Activates the transient operation
11 "INPUT ON" Turns on the load‘ s input
