3. Voltage setting

Command: VOLT X1

Function:

Function: Set the output voltage of the power supply
unit in the selected channel. This command is available
only when the rated voltage and rated current of the
selected channel are set with the MODE command.
Otherwise, this command causes a GP-IB run error.    If
the output voltage is greater than the rated voltage, a
parameter error occurs.  The output voltage is set to
zero when the GP-600B is turned on.

Parameter: X1:

Output voltage (0 to rated voltage)

The format of the numeral is XXXX.XX.

The relationship between the reference output(s) and selected
channel(s) is as shown below:

SELECT 0: References A and C

SELECT 1: Reference A
SELECT 2: Reference C

4. Current setting

Command: AMP X1

Function:

Set the output current of the power supply unit in the
selected channel. This command is available only when
the rated voltage and rated current of the selected
channel are set with the MODE command. Otherwise,
this command causes a GP-IB run error. If the output
current is greater than the rated current, a parameter
error occurs. The output current is set to zero when
the GP-600B is turned on.

Parameter: X1: Output current (0 to rated current)

The format of the numeral is

XXXX.XX.

The relationship between the reference output(s) and selected
channel(s) is as shown below:

SELECT 0: References B and D
SELECT 1: Reference B
SELECT 2: Reference D
