Warning and Caution Notices
Warning and caution notices are used throughout
this manual where applicable and should be strictly
observed. These notices appear in the format shown
below and are defined as follows:
Warning
Warning, as used in this manual, is defined as
a condition or practice which could result in
personal injury or loss of life.
Caution
Caution, as used in this manual, is defined as
a condition or practice which could result in
damage to or destruction of the equipment or
apparatus under test.
Open ground detection
1. The unit has an open ground detection circuit
with gives alarm if the mains outlet ground
is missing or different from the station/test
specimen ground. The alarm can be configured
by the user to give an alarm only or actually lock
the unit and prohibit any test signal generation.
2. The mains outlet must have a PE, protective
earth (ground) connected to station ground.
Normally mains outlet PE is connected to station
ground. If that is not the case there are two
alternatives:
▪In compliance with local safety regulations
and permits, use an isolation transformer
where the secondary side Earth/Ground is
to be connected to station ground using a
separate ground cable (not via TRAX unit!)
▪In compliance with local safety regulations
and permits, use a temporary grounding and
connect mains outlet ground with station
ground.
Instrument safety
1. This instrument operates from a single-phase
power source. It has two-pole terminal with
ground connector and requires a two-pole, 16A,
three-terminal, live, neutral, and ground type
connector. The voltage of the power source
must be within the following rated operating
voltage: 100-240 V ± 10 %, 47 / 63 Hz.
2. Before making connection to the power source,
determine that the instrument rating matches
the voltage of the power source and has a suita-
ble two-pole terminal with ground connector.

AJ0383BE ZP-AJ01E TRAX 9
2 SAFETY
3. The power input plug must be inserted only
into a mating receptacle with a ground contact.
Do not bypass the grounding connection. Any
interruption of the grounding connection can
create an electric shock hazard. Determine that
the receptacle is properly wired before inserting
the plug.
2.2 Safety instructions
1. The test set and the specimen to which it is
connected are a possible source of high-voltage
electrical energy and all persons making or
assisting in tests must use all safety practice
precautions to prevent contact with energized
parts of the test equipment and related circuits.
2. Persons actually engaged in the test must stand
clear of all parts of the complete high-voltage
circuit, including all connections, unless the
test set is de-energized and all parts of the
test circuit are grounded. Persons not directly
involved with the work must be kept away from
test activities by suitable barriers, barricades, or
warnings.
3. Treat all terminals of high-voltage power
equipment as a potential electric shock hazard.
There is always the potential of voltages being
induced at these terminals because of proximity
to energized high-voltage lines or equipment.
4. Always ground both sides of the test specimen
before connecting any leads from the test set.
Whenever possible, always keep one side of the
test specimen grounded at all times. Always use
a safety ground stick to ground any high-volt-
age conductor. Always disconnect test leads
from power equipment before attempting to
disconnect them from the test set. The ground
connection must be the first made and the last
removed. Any interruption of the grounding
connection can create an electric shock hazard.
5. It is not possible to eliminate all potential
hazards from, and in using, electrical test
equipment. For this reason, every effort has
been made to point out in this instruction
manual the proper procedures and precautions
to be followed by the user in operating this
equipment and to mark the equipment itself
with precautionary warnings where appropriate.
It is not possible to foresee every hazard which
may occur in the various applications of this
equipment. It is therefore essential that the user,
in addition to following the safety rules in this
manual, also carefully consider all safety aspects
of the test before proceeding.
6. High-voltage discharges and other sources of
strong electric or magnetic fields may interfere
with the proper functioning of heart pacemak-
ers. Persons with heart pacemakers should
obtain expert advice on the possible risks before
operating this equipment or being close to the
equipment during operation.

2 SAFETY
7. All persons making or assisting in tests must
use all practical safety precautions to prevent
contact with energized parts of the test equip-
ment and related circuits. Also follow all local
and company safety requirements. Persons
actually engaged in the test must stand clear of
all parts of the complete high- voltage circuit,
including all connections, unless the test set is
de-energized and all parts of the test circuit are
grounded. Persons not directly involved with the
work must be kept away from test activities by
suitable barriers, barricades, or warnings.
8. Safety is the responsibility of the user.
9. Misuse of this high-voltage equipment can be
extremely dangerous.
10. The purpose of this equipment is limited to use
as described in this manual. Do not use the
equipment or its accessories with any device
other than specifically described.
11. Make sure that the instrument is properly
grounded, both through its AC power cord and
through the ground connector. The AC power
cord is the disconnecting device.
12. Before making any connections, make sure that
the instrument is de-energized and that all parts
of the test circuit are properly grounded.
13. Never connect more than one output at the
time. All outputs are energized by the same
amplifier and therefore all outputs are energized
simultaneously.
14. Always disconnect test leads from test specimen
before attempting to disconnect them at the
test set.
15. The ground connection on the test set must
be the first made and the last removed. Any
interruption of the grounding connection can
create an electric shock hazard.
16. Operation is prohibited in rain or snow.
17. Do not use the test set in an explosive
atmosphere.
18. A qualified operator should be in attendance
at all times while the test equipment is in
operation.
19. Observe all safety warnings marked on the
equipment.
20. Corrective maintenance must only be performed
by qualified personnel who are familiar with the
design and operation of the test set and the
hazards involved.
Maintenance
1. DISCONNECT the MAINS plug before any
cleaning or maintenance.
2. Maintenance should be performed only by
qualified personnel familiar with the hazards
involved with high-voltage test equipment.
3. Read and understand Safety in the User Manual
before performing any service.
4. Routine maintenance is all that is required for
these test sets. The cables and connector panel
should be inspected frequently to be sure all
connections are tight and all ground connec-
tions intact.
5. The appearance of the test set can be main-
tained by occasional cleaning of the case,
panel and cable assemblies. The outside of the
carrying case can be cleaned with detergent and
water. Dry with a clean, dry cloth. The control
panel can be cleaned with a cloth dampened
with detergent and water. Do not allow water
to penetrate panel holes, because damage to
components on the underside may occur. A
household all-purpose spray cleaner can be used
to clean the panel. Polish with a soft, dry cloth,
taking care not to scratch the display screen
cover. The cables and mating panel receptacles
can be cleaned with isopropyl or denatured
alcohol applied with a clean cloth.

knob on panel.
1] Press to change value for the incremental
steps (e.g. 1 V, 2 V, 5 V, 0.1 V).
2] Press and drag acording to the arrows to in-
crease / decrease the value.
Generator settings
1] Press to make the generator settings.
2] Press the “Output” button to select generator
output.
The following outputs are connected internally to the
same output transformer and should be considered
“live” when one of the outputs is activated.
▪0-250 V / 10 A AC
▪0-800 (200) A AC
The 2.2 kV output is additionally disconnected with a
relay and the output is “live” only when this genera-
tor is selected.
The 1, 16 and 100 A DC current outputs are intended
for resistance measurements.
3] Make settings for “Fequency”.
4] Select “Manual” or “Ramp”.
In manual mode the generator is started instantly. A
max generating time can be set.
In ramp mode, the output signal amplitude is
increased continuously, hold at the set value and
decreased back to zero. Ramp and hold times are
selectable.
Note The Manual Control is not designed for
resistance measurements on inductive loads.
If Manual Control is used for this, manual
setting with small and slow adjustment of test
current should be used. For measuring highly
inductive loads, e.g. transformer windings, the
winding resistance instrument should be used.
Instrument settings
1] Press
Integration /
measurement
time time
Integration time for the individual
measurement record
Averaging Number of averaged measurement
records in the measured value
Display update
frequency
Time interval for updating dis-
played values
Example: 1,1,1 means that a measurement is per-
formed over 1 s, no additional averaging and the
display is updated every second. 3,2,1 means that
a measurement is performed over 2 seconds and 3
measurements are averaged. The display shows a
running average every second.
Data capture and hold at generator stop
Make desired action at generator stop, “Hold on
stop” and/or “Store on stop”.
Instrument channel selection
1] Press to select measurement channels.
