instrument was purchased.
General
Guideline
CAUTION
Do not place any heavy object on the PSW.
Avoid severe impact or rough handling that
leads to damaging the PSW.
Do not discharge static electricity to the PSW.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the PSW unless you are
qualified.
(Measurement categories) EN61010-1:2010 and EN61010-2-030
specify the measurement categories and their requirements as
follows. The PSW falls under category II.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.

PSW Series Programming Manual
Cleaning the PSW
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
(Pollution Degree) EN61010-1:2010 and EN61010-2-030 specify the
pollution degrees and their requirements as follows. The PSW falls
under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom
When using the power supply in the United Kingdom, make sure
the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

Structure
SCPI commands follow a tree-like structure,
organized into nodes. Each level of the
command tree is a node. Each keyword in a
SCPI command represents each node in the
command tree. Each keyword (node) of a SCPI
command is separated by a colon (:).

PSW Series Programming Manual
Query
A query is a simple or
compound command
followed by a question mark
(?). A parameter (data) is
returned.
Example
meas:curr:dc?
Compound
Two or more commands on
the same command line.
Compound commands are
separated with either a semicolon (;) or a semi-colon and a
colon (;:).
A semi-colon is used to join
two related commands, with
the caveat that the last
command must begin at the
last node of the first
command.
A semi-colon and colon are
used to combine two
commands from different
nodes.
Example
meas:volt:dc?;:meas:curr:dc?

Command Forms
Commands and queries have two different
forms, long and short. The command syntax is
written with the short form of the command in
capitals and the remainder (long form) in lower
case.
The commands can be written in capitals or
lower-case, just so long as the short or long
forms are complete. An incomplete command
will not be recognized.
Commands that contain square brackets
indicate that the contents are optional. The
function of the command is the same with or
without the square bracketed items, as shown
below.
Both “DISPlay:MENU[:NAME]?” and
“DISPlay:MENU?” are both valid forms.

Status Register Overview
To program the PSW power supply effectively,
the Status registers need to be understood. This
chapter explains in detail how the Status registers
are used and how to configure them.

REMOTE CONTROL
Overview
The Questionable Status Register Group
indicates if any protection modes or limits have
been tripped.
The Questionable Status Condition Register
indicates the status of the power supply. If a bit
is set in the Condition register, it indicates that
the event is true. Reading the condition register
does not change the state of the condition
register.
PTR/NTR Filters
The PTR/NTR (Positive/Negative transition)
register determines the type of transition
conditions that will set the corresponding bit in
the Event Registers. Use the Positive transition
filter to view events that change from false to
positive, and use the negative transition filter to
view events that change from positive to
negative.
Positive Transition
0→1
Negative Transition
1→0
Event Register
The PTR/NTR Register will dictate the type of
transition conditions will set the corresponding
bits in the Event Register. If the Event Register
is read, it will be cleared to 0.
Enable Register
The Enable register determines which Events in
the Event Register will be used to set the QUES
bit in the Status Byte Register.
98
REMOTE CONTROL
Overview
The Operation Status Register Group indicates
the operating status of the power supply.
The Operation Status Condition Register
indicates the operating status of the power
supply. If a bit is set in the Condition register, it
indicates that the event is true. Reading the
condition register does not change the state of
the condition register.
PTR/NTR Filters
The PTR/NTR (Positive/Negative transition)
register determines the type of transition
conditions that will set the corresponding bit in
the Event Registers. Use the Positive transition
filter to view events that change from false to
positive, and use the negative transition filter to
view events that change from positive to
negative.
Positive Transition
0→1
Negative Transition
1→0
Event Register
The PTR/NTR Register will dictate the type of
transition conditions will set the corresponding
bits in the Event Register. If the Event Register
is read, it will be cleared to 0.
