DESCRIPTION OF COMMON COMMANDS
Common commands begin with an * and consist of three letters (command) or three letters and a “?”
(query). They are defined by the IEEE 488.2 standard to perform common interface functions. The PD
series power supply responds to the following commands:
*CLS
Meaning and Type
Clear Status Device Status
Description
This command causes the following actions (see "Status Reporting" for descriptions of all registers):
x Clears the following registers:
o Standard Event Status (“*ESR?” returned value)
o Status Byte (“*STB?” returned value)
x Clears the Error Queue (“SYST:ERR?” returned value)
x Also clears over-voltage protection status (to comply with AMREL old 488.1 unit).

Meaning and Type
Event Status Enable Device Status
Description
This command programs the Standard Event Status Enable register bits. The programming value
determines which events of the Standard Event Status Event register (see *ESR?) are allowed to set the
Event Summary Bit of the Status Byte register. A "1" in the bit position enables the corresponding event.
All of the enabled events of the Standard Event Status Event register are logically ORed to cause the Event
Summary Bit of the Status Byte register to be set.
Bit Configuration of Standard Event Status Enable Register Table:
Bit Position 7 6 5 4 3 2 1 0
Bit Name PON 0 CME NU NU
QYE
0 OPC
Bit Weight 128 64 32 16 8 4 2 1
CME = Command error; OPC = Operation complete; PON = Power-on; QYE = Query error;
NU = Not used.
