(0-15 V) and high range (0-150 V).
(1) In the main interface, press V_Range to switch the parameter focus to
"V_Range".
(2) Press V_Range to switch the voltage working range. You can also use the
Left/Right arrow key or the knob to switch it.
Note:

The low range provides better resolution and accuracy at low voltage settings.

If the set current value is greater than the maximum value of the low range, you
must select a high range.
CAUTION
Before switching the voltage range, please disable the channel
input to avoid causing damage to the instrument or the DUT.
Set V_Limit
The upper limit of the voltage working in CC+CV mode. The default unit for V_Limit
is V, and it ranges from 0 V to 155 V.
(1) In the main interface, press V_Limit to switch the parameter focus to "V_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 C_Limit
The upper limit of the current working in CC+CV 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".
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.
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!"
