2.4.3 Constant Resistance Measurement Mode
In constant resistance mode, the load is equivalent to a constant resistance, and the load will
consume a correspondingly varying current as the input voltage changes.
Operation instructions: 1. Press the [CH] key to select the operation channel; 2. Select the
operation item by rotating the knob; 3. Set the parameters. Press [Enter] to enter the edit
mode, use the arrow keys to select the corresponding number of digits, then adjust the value
by turning the knob, [Enter] or [Shift] + [
▶
] (Esc) to exit editing; 4. Press the corresponding
[On1], [On2] startup mode.

2.4.4 Constant Power Measurement Mode
In constant power mode, the load consumes a constant amount of power. When the input
voltage changes, the load will adjust the current to maintain the power consumption at the set
power value.
Operation instructions: 1. Press the [CH] key to select the operation channel; 2. Select the
operation item by rotating the knob; 3. Set the parameters. Press [Enter] to enter the edit
mode, use the arrow keys to select the corresponding number of digits, then adjust the value
by turning the knob, [Enter] or [Shift] + [
