Therefore, as far as triggers are concerned, OPC is false whenever the trigger
system is in the Initiated state.
Using Device Clear
You can send a device clear at any time to abort a SCPI command that may be
hanging up the GPIB interface. The status registers, the error queue, and all
configuration states are left unchanged when a device clear message is
received. Device clear performs the following actions:
 The input and output buffers of the electronic load are cleared.
 The electronic load is prepared to accept a new command string.
The following statement shows how to send a device clear over the GPIB
interface using GW BASIC:
CLEAR 705 IEEE-488 Device Clear
The following statement shows how to send a device clear over the GPIB
interface using the GPIB command library for C or QuickBASIC.

1.9 Remote Operation
IT8800 series electronic load is provided with three communication interfaces
to communicate with a computer for selection, including RS232, USB, and
GPIB.
GPIB function
All electronic load functions except setting the communication parameters are
programmable over the GPIB. The IEEE 488.2 capabilities of the electronic
load are described in the following table.
GPIB Capabilities
Response
Interface
Function
Talker/Listener
All electronic load functions except for setting the communication
paraments are programmable over the GPIB. The electronic
load can send and receive messages over the GPIB. Status
information is sent using a serial poll.

T6, L4T6, L4
Service Request
The electronic load sets the SRQ line true if there is an enabled
service request condition.
SR1, SR1
Remote/Local
In local mode, the electronic load is controlled from the front
panel but will also execute commands sent over the GPIB.
If the electronic load is powered on in local mode, it remains in
local mode until it receives a command over the GPIB.
Once the electronic load is in remote mode the front panel REM
indicator is on, all front panel keys (exceptShift+7,Local and
Esc) are disabled, and the display is in normal metering mode.
Press Local on the front panel to returnto the local mode.
RL1
Device Trigger
The electronic load responds to the device triggers.
DT1
Group Execute
Trigger
The electronic load responds to the group execute triggers.
GETGET
Device Clear
The electronic load responds to the Device Clear (DCL) and
Selected Device Clear (SDC) interface commands. They
command the electronic load to clear any activity that would
prevent it from receiving and executing a new command
(including *WAI and *OPC?). DCL and SDC do not change any
programmed settings.
