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.

Power cord for the United Kingdom
When using the tester 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.

GCT-9040 Overview
Introduction to the GCT-9040
GCT-9040 is a ground bond tester that can operate as a standalone
unit or in conjunction with a GPT-9000 Series safety tester to
perform additional ACW/DCW/IR tests before, after or
simultaneously(ACW/DCW only) with GB tests.
When the GCT-9040 operates with a GPT-9000 Series safety tester,
it uses a dedicated LINK port and remote commands to
communicate in a master-slave fashion. The GCT-9040 operates as
the master and the GPT-9000 Series unit operates as a slave.
The GCT-9040 can store up to 100 manual tests allowing the safety
testers to accommodate any number of safety standards, including
IEC, EN, UL, CSA, GB, JIS and others.
Note: Throughout this user manual, the terms ACW, DCW, IR and
GB refer to AC Withstanding, DC Withstanding, Insulation
Resistance and Ground Bond testing, respectively. GPT-9000 refers
to any of the GPT-98XX or GPT-99XX models, GPT-9000A refers to
any of the GPT-99XXA models. For information specific to the GPT9000, please see the GW Instek website, http://www.gwinstek.com.

Background
The GCT-9040 operates with the SOURCE L
terminal floating with respect to the earth
ground. For the GCT-9040 and GPT-9XXX
Series, this is referred to as having the
GROUND MODE is set to OFF. On the GCT9040 this mode is fixed.
When performing additional ACW or DCW
tests, a slave GPT-9XXX Series unit can operate
with the GROUND MODE set to ON or OFF.
Grounding Mode Note
33
Page 34
Overview
GROUND MODE = OFF
This mode is for DUTs that are floating and not
directly connected to an earth ground. When
GROUND MODE is set to OFF any stray
capacitance/resistance that leaks to the earth
ground from the DUT side of the testing circuit
are not measured. GB and IR tests must operate
with GROUND MODE = OFF.
GROUND MODE = ON
When GROUND MODE is set to ON, the GPT9XXX grounds the return terminal to the
ground. This mode measures the potential of
the HIGH VOLTAGE terminal with respect to
earth ground. This means that any stray
capacitance/resistance that leaks to earth
ground will also be measured.
For further details about the grounding mode
for the ACW, DCW and IR tests, please see the
GPT-9XXX user manual.

Linked ACW/DCW/IR Tests
This section describes how to perform additional ACW, DCW or IR
tests with a slave GPT-9XXX unit using the GCT-9040 as the master
unit. ACW and DCW tests can be performed before, after or
simultaneously with a GB test. IR tests can only be performed
before or after a GB test.
The LINK port on the GCT-9040 is used to control the linked slave
unit. The slave unit can be used in MANU or AUTO mode,
depending on the setup. In addition, remote commands can also be
issued to slave units via the GCT-9040.
LINK Connection → from page 58
LINK Test Configuration→ from page 60
Run LINK Test→ from page 63
Before operating the GCT-9040 please read the safety precautions
as outlined in the Set Up chapter on page 19 as well as the safety
information in the user manuals’ of the GPT-9XXX units that
function as the slave units when using the link connection.
57
Page 58
GCT-9040 User Manual
Background
Any GPT-98XX or GPT-99XX unit can be used
in conjunction with the GCT-9040 to perform
additional ACW, DCW or IR tests.
The LINK port on the GCT-9040 and the RS-232
port on the slave unit is used to connect both
devices. The GPT-9XXX interface should be
configured to the RS-232, with a baud of
115200.
Steps
1. Ensure the power is off on both the GCT-9040
and the GPT-9XXX slave unit.
2. Connect the LINK cable (GTL-132) to the LINK
port on the GCT-9040 and to the RS-232 port on
the GPT-9XXX unit.
3. Connect the DUT as shown on page 30.
Note: Stack the units vertically to use the cable.

GCT-9040 User Manual
Note
First ensure the GPT-9XXX interface s set to RS232 and that the baud rate is set to 115200. See the
Remote Control chapter of the corresponding user
manual for configuration details. Not setting the
interface correctly will result in failure of the LINK
mode connection.
Steps
1. Turn on both units after the link cable has been
connected*.
2. The GCT-9040 will be in VIEW mode upon
startup.
Note
*The GCT-9040 will perform a search to see if a
slave unit is connected with the LINK cable upon
startup. If the slave GPT-9XXX is found then the
LINK connection will automatically be activated at
startup. Note, however, that the GPT-9XXX unit will
need to have been fully powered on before the
GCT-9040 is powered on for the search to succeed.

Description
The Control settings are accessed in the
COMMON UTILITY menu. The Control
settings include: Start Control, Double Action,
Key Lock and Interlock.
Start Control is used to determine how a test is
started. Tests can be started via the front panel
(START/STOP buttons), from a remote
controller or via the SIGNAL I/O port.
The Double Action function is a safety feature
used to prevent accidentally starting a test.
Normally to start a test, the START button is
pressed when the tester is in the READY status.
To start a test when Double Action is ON, the
STOP button must first be pressed, followed by
the START button within 500ms.
Key Lock disables the front panel keys from
changing the test number, mode or testing
parameters. Only the Utility menu and any
keys required for testing are not disabled.
The Interlock function is a safety feature. The
interlock function prevents a test from running,
unless the interlock pins on the signal I/O port
connector are shorted. The included interlock
key can be used for this purpose. See page 80
for details.

Description
The GCT-9040 accepts external remote
controllers with a START and STOP button. To
use the REMOTE terminal, the
GCT-9040 must first be configured to accept a
remote controller.
Operating a remote controller is the same as
operating the START and STOP buttons on the
front panel.
Steps
1. Insert the lead of the remote
controller into the REMOTE
terminal.
REMOTE
2. Configure the Start Ctrl option to
REMOTE CONNECT in the
Common Utility menu.
Page 70
3. The tester will now only be able to
start a test using a remote
controller.
NOTE
Even if the GCT-9040 is configured to use the
REMOTE CONNECT option, the STOP button on
the front panel can still be used to stop a test.
4. To return the operation control to
the front panel, configure the Start

Structure
SCPI commands follow a tree-like structure,
organized into nodes. Each level of the
command tree is a node. Each keyword in an
SCPI command represents each node in the
command tree. Each keyword (node) of an SCPI
command is separated by a colon (:).
For example, the diagram below shows an SCPI
sub-structure and a command example.

Command types
There are a number of different instrument
commands and queries. A command sends
instructions or data to the unit and a query
receives data or status information from the
unit.

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
