3.3 Set output parameters
The voltage value and current value can be programmed, which can be set to
different parameters within the specification range based on customer
requirements. This can meet various test requirements of the customer.
After the user presses the [V-set] or [I-set] keys on the front panel, the
instrument interface displays the parameters to be set and the cursor flashes for
prompt. The user can use the following methods to set the values.

Directly use the number keys to set the value.

Rotate the knob to set the data in the cursor position. Rotate the knob
lockwise to increase the set value and anticlockwise to decrease the set
value. Once the data in the cursor position increases to ten, the value will
add one to the front position automatically. and once the data in the cursor
position decreases to zero, the value will minus one from the front position
automatically. This provides convenience for the user to set. The knob can
works with the left or right keys. Use the left or right keys to move the cursor
position.
3.4 Output On/Off Control

The [On/Off] key is used to turn the output on or off under normal
circumstances. Even if the instrument is in control by PC or the keyboard is
locked, the [On/Off] is still valid.

The [On/Off] key light is off and turning the output off does not place the
instrument in a safe state. Hazardous voltages may be present on all output
and guard terminals. Putting the equipment into an output-off state does not
guarantee that the outputs are powered off if a hardware or software fault
occurs. See the cautions about connecting the test lines before connecting
test lines.
Controlled by the [On/Off] key
User can control the output switching of the instrument's 2 channels by pressing
the [CH1 On/Off] key and the [CH2 On/Off] key on the front panel. If the [On/Off]
key light is on, indicates that the output is turned on. The meter area on the
interface will display the voltage, current, and power values in the current circuit.
If the [On/Off] key light is off, indicates that the output is turned off. The LCD
displays that the power supply state is OFF.
Controlled by Digital IO pins
The Digital IO pin, which comes standard with this series of instruments,
supports external level/pulse signal control output, and in combination with
external circuitry, enables emergency stop control of the output. Refer to the
following use case.
Case:
Pin 5 of Digital IO has an INTERLOCK function. In the default settings of
Reverse (Off) and Inhibit-Living, pulling pin 5 low (0V) can disable the
machine's output. At this point, the [On/Off] key light is on, but there will be no
NOTE
After entering the menu interface, the knob can also be used to scroll pages to view menu
items.
