Programmable DC Power Supply 62000L Series User’s Manual
4-8
This command is used to clear the overvoltage protection tripped event. After commanding,
the output voltage is restored to the state in which it was before the protection feature
occurred and the OVP trip level keeps unchanged to the value presently programmed. Before
clearing the tripped event, keep the output voltage lower than the trip OVP point, or adjust the
OVP trip level more greatly than the output setting.
MEASure[:VOLTage]?
This command is used to query the voltage output value measured by the power supply. The
reading value is returned in the scientific format.
4.2.2 Triggering Commands
The power supply under the triggering system allows a change in voltage and current when
receiving a trigger. In addition, it also allows to you to select a trigger source, and to insert a
trigger. To trigger the power supply, you need to finish the following multi-step process.

First of all, you have to specify the source from which the power supply will accept the
trigger. A bus (software) trigger or an immediate trigger from the remote interface is
acceptable.

After that, the time delay between the detection of the trigger on the specified trigger
source and the start of any corresponding output change is available to be set.
Note The time delay is feasible for the bus trigger source only.

At last, you have to provide an INITiate command. If selecting the IMMediate source, the
selected output will be set to the triggered level right away. However, if the trigger source
is the bus, your power supply will be set to the triggered level after receiving GET (the
Group Execute Trigger) or
*TRG command.
The following commands are collected and used to deal with triggering. For more detailed
description, please check from the
section 4.2.2.1 and 4.2.2.2 .
INITiate[:IMMediate]
TRIGger[:SEQuence]
:DELay {<seconds>|MIN|MAX}
:DELay?
:SOURce {BUS|IMM}
:SOURce?
*TRG
4.2.2.1 Trigger Source Options
You have to specify the source from which the power supply will accept the trigger. In addition,
the trigger is stored in volatile memory. And the source is set to bus after powering on the
power supply or resetting a remote interface.
Bus Triggering:

Send TRIG:SOUR BUS to select the bus trigger source.

Send *TRG to trigger the power supply via the remote interface, such as USB or GPIB
after selecting the bus source. When sending this command, the trigger acts after the
specified time delay if any delay is given.
