Local Operation 87
The voltage step keys can also be used to change the voltage setting.
VSET
ÑVOLT
or
ÒVOLT
then ENTER
The voltage can be set in the immediate execute mode. This mode is in effect when background
metering is in effect. Pressing
ÑVOLT
or
ÒVOLT
will change the setting
and the effect on the voltage and current can be observed on the display.
The voltage range can be changed by using the RANGE V/I key and the voltage step keys.
RANGE V/I
ÑVOLT
or
ÒVOLT
The range will change as soon as one of the voltage step keys is pressed and the display will be updated. If the voltage
setting is greater then the highest value of the low range and the range is changed from high to low, the VSET will be
automatically reduced to the maximum voltage of the low range.
Setting Current and Current Range
The selected output’s current is programmed locally using the ISET key. For example, program the current to 1.5 amps by
pressing:
ISET 1 . 5 ENTER
The power supply will accept any programmed current between zero and the minimum programmable current and
automatically set the output to the minimum programmable current without causing a programming error. See Table 5-4.
The current step keys can also be used to change the current setting.
ISET
ÑCURR
or
ÒCURR
then ENTER
The current can be set in the immediate execute mode. This mode is in effect when background
metering is in effect. Pressing
ÑCURR
or
ÒCURR
will change the setting
and the effect on the voltage and current can be observed on the display.
The current range can be changed by using the RANGE V/I key and the current step keys.
RANGE V/I
ÑCURR
or
ÒCURR
The range will change as soon as one of the current step keys is pressed and the display will be updated. If the current
setting is greater then the highest value of the low range and the range is changed from high to low, the ISET will be
automatically reduced to the maximum current of the low range.
Enabling/Disabling an Output
The selected output channel can be turned on and off from the front panel. The OUTPUT ON/OFF key toggles the selected
output on and off. When an output is turned off, the message "DISABLED" will be displayed.
The OUTPUT ON/OFF key will not affect any other programmed functions nor will it reset an overvoltage or overcurrent
condition. An output disabled by the OUTPUT ON/OFF key will behave as if it were programmed to zero volts and 10 mA.
