OFF CC
0.0001V 0.0002A
0.00W 0.0000S CC=0.000A
Measurement of rise time
9. Connect DC power to be tested to the input terminal of the electronic load.
The power is set with a value that is higher than the set final voltage value.
Keep power output in OFF status.
10. Set a constant current value on the load and open the load input.
11. Open power output.
12. The electronic load timer starts timing. After ending, time will keep stable,
which is rise time of voltage.
13. Close the power output. The electronic load VFD will display voltage drop
time.
3.15 Configuration save function
The electronic load can save some commonly-used parameters in 100-group
NVM for convenient and fast usage. Saving parameters comprise working
mode, voltage, current, etc. The [Shift] + [4] (Save) keys can be used for
saving parameters. The [Shift] + [Enter] (Recall) key is for quick invoking.
Operation steps
If the operator needs to save configured parameter values for direct recall in
follow-up operation, refer to the steps below:
E.g., power supply 6V and 3A. The electronic load works under constant
current (CC) 1A. Save "CC 1A" in register 9 for recall.
 SAVE
1. Set parameters and press [Shift] + [4] keys to save data. Press [9] key
(to select in which group the data is to be saved).
5.8949V 0.99994A
5.89W SAVE 9
2. Press [Enter] key.
5.8949V 0.99994A
5.89W cc=1.000A
 RECALL
1. Press [Shift] + [Enter] (Recall) key and press [9] (to select from which
group the data is recalled).
5.8949V 0.99994A
5.89W cc=1.000A
3.16 VON function
When testing some power products with slow voltage rise speed, if the
electronic load input is opened before power, the power may latch protection. In
this way, the user may set VON value. The electronic load only latches when
power voltage is higher than this value.
Press [Shift] + [9] keys to enter configuration menu. Set voltage value in
Voltage on under configuration menu to control on/off status of electronic load.
When VON LATCH function is started, it indicates that Von Point latches load
