EX Series Operating Manual
7-3. Apply Commands.
The
APPLy
command provides to control the output voltage and current by remote interface.
APPLy {<voltage>}[,<current>]
> voltage Input voltage value
> current Input current value
ex1) APPL 30 5
Voltage is 30V current is 5A
ex1) APPL 30,5
Voltage is 30V, current is 5A.
ex2) APPL 5
Jist set voltage to 5V excepted current set.
APPLy?
Only the
APPLy?
will instruct the power supply to send a response message about voltage
and current value. Between return value, the former is vlotage value, the latter is current.
Return value "voltage,current"
ex) APPL?
return value "30 00 5 000"
ex) APPL?
return value "30.00 ,5.000"
7-4. Output V/I Setting & Oprating Commands.
This section describes low-level commands used to program the power supply. Although the
APPLy
command provides the most straightforward method to program the power supply, the
low-level output setting commands give you more flexibility to change the individual parameters.

VOLT {<voltage>|UP|DOWN}
This command programs the immediate vlotage level of the power supply. The immediate level is
the voltage value of the output terminals.
This command also increases or decreases the immediate voltage level using the ‘‘UP’’ or
‘‘DOWN’’ parameter by a predetermined amount. The command VOLTage:STEP sets the amount
of increase or decrease.
> Voltage
Input voltage value.
> UP
Increase voltage setting value as step value.
> DOWN
Decrease voltage setting value as step value.
ex1) volt 10
Set the voltage 10V.
ex2) volt up
Increase voltage setting value as step value..
Note
If you operated "*RST" command, voltage step value returned to the unit's default value.
About "*RST" command, refer to "*RST" command chapter.
VOLT?
This query returns the presently programmed voltage level of the power supply.
Return value "voltage"
ex) volt?
return value "30.00"
VOLT:STEP {<numeric value>}
This command sets the step size for voltage programming with the
VOLTage
UP and
VOLTage
DOWN commands.
> numeric value
Program the power supply to the allowed setting value resolution.
ex) volt:step 0 5
Set the voltage to 0 5V
ex) volt:step 0.5
Set the voltage to 0.5V .
