Set C_Limit

The upper limit of the current working in CR mode. The default unit for C_Limit

is A, and it ranges from 0 A to 70 A.

(1) In the main interface, press C_Limit to switch the parameter focus to

"C_Limit".

(2) Enter a value by using the numeric keys, arrow keys, or the knob. For setting

methods, refer to the descriptions of the help information or refer to the

descriptions in "Parameter Setting Method".

Set Von

When the input voltage is greater than the set starting voltage (Von), the load

starts to sink the current. The default unit for Von is V, and it ranges from 0 V to

150 V. The default Von is 0 V. To enable or disable this function, refer to

descriptions in "Enable/Disable the Von Latch Function".

(1) In the main interface, press Von to switch the parameter focus to "Von".

(2) Enter a value by using the numeric keys, arrow keys, or the knob. For

setting methods, refer to the descriptions of the help information or refer to

the descriptions in "Parameter Setting Method".

4. Turn on the channel input

Press On/Off to turn on the channel input. At this time, the actual input

voltage, current, resistance, and power will be displayed in the main interface.

Note: Once the channel input is turned on, the load will not start to sink the

current until the input voltage is greater than the starting voltage.

WARNING

To avoid electric shock, ensure that the DUT is connected to the

input terminals of the load properly before you turn on the channel

input.

CAUTION

When the fan stops working, the channel is disabled. Then, a

message is displayed, "Fan stops running!"

5. View waveform display

Press the waveform display key to enter the waveform display interface,

as shown in Figure 2-10. When you select "R" under "Data", you can view the

resistance waveform. When changes occur to the input voltage, the current

changes linearly to keep the resistance value unchanged. For detailed

operations, refer to the descriptions in "Waveform Display Function" section.

Press the waveform display key again to exit the waveform display

interface and return to the main interface of CR mode.
