Language Dictionary

Commands for operating the 63200A Electronic Load remotely are grouped into subsystems.
Each command that belongs to the same subsystem is arranged in alphabetic order. A
syntax chart of the subsystem that contains the commands in the same group is included.
Sub- systems are ordered alphabetically according to their names in the following sections.

*ESR? Standard Event Status Register Query
Type:
Description:
Device Status
The *CLS command executes the following actions:
■
Clear these registers
<1> Channel Status Event registers for all channels
<2> Channel Summary Event register
<3> Questionable Status Event register
<4> Standard Event Status Event register
<5> Operation Status Event register
■
Clear the Error Queue
■
If "Clear Status Command" immediately follows a program
message terminator (<nl>), the "Output Queue" and the MAV bit
are also cleared.
*CLS
Device Status
This command sets the condition of the Standard Event Status
Enable register to determine which event (see *ESR?) is allowed to
set the ESB (Event Summary Bit) for the Status Byte register. A "1"
in the bit position enables the corresponding event. All of the
events that enabled by Standard Event Status register are logically
ORed to cause the Status Byte register ESB (bit 5) to be set. See
descriptions of these three registers in Chapter 5.
*ESE<space><NR1>
*ESE 48 This command enables the CME and EXE events for
the Standard Event Status register.
*ESE?
*ESE? This query returns the current setting for "Standard
Event Status Enable".
Device Status
This query reads the Standard Event Status register. Reading the
register clears it. See detailed explanation of this register in
