Operation
Operating Modes
The electronic load can work in the following modes:
1)
Constant current (CC) operation mode
2)
Constant voltage (CV) operation mode
3)
Constant resistance (CR) operation mode
4)
Constant power (CW) operation mode
5)
Constant impedance (CZ) operation mode
Constant Current (CC) mode
In this mode, the electronic load will sink a current in accordance with the programmed value
regardless of the input voltage.
Figure 16 - Constant Current Mode
Ranges
When working in CC mode, you can press the Setup key to enter the RANGE menu. Two
overlapping ranges can be selected: LOW RANGE or HIGH RANGE. Current can be edited in either
of the two ranges. Low range will supply higher accuracy and better resolution when you set lower
current. If any value you set is outside the maximum value of the LOW RANGE, you should select
HIGH RANGE. If the electronic load is in remote control mode, you can use the CURR:RANG
command to switch current range.
