Applications
1.1
PROFITEST 204+
The PROFITEST 204+ test instrument is used for quick and safe
testing of electrical and electronic equipment and systems at
machinery in accordance with DIN VDE 0113/EN 60204-1.
The following initial and periodic tests must be performed in
accordance with these regulations:
• Testing for continuity of the protective conductor circuit with a
test current of at least 10 A
• Insulation resistance test
• Voltage test (optional PROFITEST 204HP/HV)
• Testing for residual voltage
Beyond this, other tests can be performed which are not required
for the safety of electrical equipment at machinery, but which
nevertheless supplement the instrument in a practical fashion:
• Measurement of electrostatic discharge capacity for floor
coverings in accordance with DIN 51953
• Leakage current test for the substantiation of the absence of
voltage
• Voltage and frequency measurements
All values required for approval reports can be measured with this
instrument.
The optional SECUTEST SI+ module (an input module which can be
set into the lid of the instrument and which is equipped with an
integrated interface and keypad) expands the applications range
of the PROFITEST 204+.
All measured data can be archived with the measuring and test
report which can be printed out directly or at a PC. This is
especially important where product liability is concerned.

1.2
PROFITEST 204L
The PROFITEST 204L test instrument has been furnished with
an extra-long measurement and control cable, allowing for
comfortable use at large machines and machine components.
Please note that use of the LEADEX 204 extension cable is
only possible to a restricted extent as a result of this extra-long
measurement cable.
Due to the additional, relatively high ohmic resistance of the
LEADEX 204 extension cable, the minimum test current of
10 A AC as specified by EN 60204 may be fallen short of under
certain circumstances, causing the instrument to abort the test
and display a corresponding message. As a rule, this does not
occur during use of the LEADEX 204 extension cable until
protective conductor resistance at the device under test has
reached a value of 200 mΩ or greater. This effect may even occur
with relatively low line voltage values (less than 210 V).
If you require longer measurement cables than those supplied
with the PROFITEST 204L for your application, we recommend the
use of extension cables with a significantly larger
cross-section.
Our product support team (see address on page 74) would be
happy to assist you with any questions you may have.
!
Attention!
Protective conductor and high-voltage test
It is imperative that the measuring cables are completely
unwound prior to starting the tests.

2.2
Special Safety Precautions and Instructions for the
PROFITEST 204HP/HV High-Voltage Module
Precautions for the prevention of unauthorized activation:
General Safety Precautions
• Key Switch
• Integrated signal lamps identify the operating status of the test instrument.
• Test voltage is electrically isolated from mains power. This
prevents heavy current from flowing to ground via the
high-voltage pistol with switch.
• Current Limiting in the Event of Sparkover:
If the current limiting value entered as a parameter is exceeded
in the event of sparkover, the instrument is automatically
switched to the stand-by mode.
• The instrument is automatically switched to the stand-by mode
when power is restored after a mains failure.
Precautions for the prevention of unintentional activation:
• Multiple Key Operation:
It is only possible to activate test voltage with the trigger at the
high-voltage pistol with switch, after pressing the start key at
the basic instrument.
• Two-Hand Operation:
Each of the high-voltage pistols is equipped with its own
trigger. The test probes are only made accessible when both
triggers are pulled and held simultaneously.
• High-Voltage Pistol with Switch (pistol with yellow marking)
Includes double safety feature:
The test probe is made accessible after the trigger at the
high-voltage pistol with switch has been pulled to its initial
mechanical limit stop. High-voltage is not switched to the test
probe until the trigger is pulled beyond this position, assuming
the instrument is in the “ready to activate” state.
12
!
Attention!
The ventilation slots at the bottom of the high-voltage
module and at the connector panel of the basic
instrument must remain unobstructed!
GMC-I Messtechnik GmbH
!
!
Attention!
Observe regulations set forth in EN 50191,
“Erection and operation of electrical test equipment”.
Attention!
If safety test probes are used, the operator must make certain that the probe tips and the connector cables are in
flawless condition before beginning work.
All utilized equipment must be inspected for visibly
apparent external damage and defects before use (see
chapter 11.2, page 66, through chapter 11.4, page 67).
Danger: High-Voltage!
The test probe is made accessible after the trigger at
the high-voltage pistol with switch has been pulled to its
initial mechanical limit stop. High-voltage is not switched
to the test probe until the trigger is pulled beyond this
position, assuming the instrument is in the “ready to
activate” state.
Danger: High-Voltage!
Touch neither the test probes nor the device under test
during the voltage test!
A life endangering high-voltage of up to 5 kV is present at
the high-voltage module test probes!
Exclusion of Liability
!
Attention!
It is imperative that the measuring cables are completely
unwound prior to starting the high-voltage test.
!
Attention!
Make sure that all points of access to the danger zone
have been secured before testing is started, and that no
persons remain within the danger zone when the system
is made ready for activation.
GMC-I Messtechnik GmbH
In the event of a sparkover, PCs which are operated in proximity
may crash, causing data loss in the process. Please therefore
ensure, prior to conducting the high-voltage test, that all data and
programs are saved appropriately and that the computer is
switched off, if necessary. This phenomenon may even occur
without an RS232 connection.
The manufacturer of the test instrument assumes no liability for
any direct or indirect damage to computers, peripheral equipment
or data stocks in connection with the execution of high-voltage
tests.
Furthermore, the manufacturer assumes no liability for defects in
DUTs caused by high-voltage tests. This applies especially for
electronic components within devices.
Please also observe the checklist for high-voltage tests given in chapter

4.1
Protective Conductor Test
Uninterrupted connection of a protective conductor system is
tested here by using an alternating current of approximately 10 A
with a line frequency of 50 Hz. Testing must be conducted
between the PE terminal and various points within the protective
conductor system.
If resistance values of less than 1.00 Ω occur, voltage drop ΔU for
respective protective conductor resistance is displayed. This is the
calculated voltage value based upon a 10 A test current in
accordance with DIN VDE 0113.
Voltage at the test probes is displayed for resistance values of
1.00 Ω to 25.0 Ω, and for over-ranging (> 25.0 Ω), because
calculated voltage drop ΔU based upon 10 A would lead to
unrealistically high results in this case.
After expiration of the test duration, the highest measured
protective conductor resistance value and the corresponding
voltage drop value are displayed.
Always assure that adequately good contact has been established with the device under test before starting the test. The test
can be started with the key (20) on the test probe (17) if preferred.
If test current drops to a value of less than 10 A during the
selected test duration, a corresponding message appears at the
display. However, testing is continued normally. In the event of
poor contact or if the test probes are not connected, testing is
aborted.
If voltage is present at the test probes after measurement has
begun*, no measurement is performed. Interference voltage at test
probes appears at the display, and a STOP signal is displayed simultaneously.
* this message may be displayed in the case of interrupted protective conductor
connections as well, as external voltages have been included capacitively here.

TEST
Select the desired test.
The limit value setting for protective conductor resistance is
based upon the cross-section of phase conductor L and, if
applicable, neutral conductor N, and not the cross section of
protective conductor PE. This is necessary because cables with
phase conductor cross-sections of greater than 16 square mm
are equipped with protective conductors of reduced crosssection, and selection on the basis of protective conductor crosssection would not be unequivocal.
A rated current (nominal current) is assigned to the phase
conductor cross-section for the respectively utilized overcurrent
protection device, as shown in the following table. The table can
be displayed from the TEST menu in order to simplify selection as
an aide to the protective conductor test function.

connector cable.
➭ If applicable, check to see whether or not the nominal current
of the utilized overcurrent protection device is allocated to the
phase conductor cross-section. If an overcurrent protection
device with low nominal current is used, you can determine the
limit value on the basis of the phase conductor current
assigned to this nominal current.
➭ Select the limit value on the basis of the triggering characteristics
offered for the various overcurrent protection devices.
If your machine/system includes components with different power cable
cross-sections (e.g. fans, pumps etc.), and if these are equipped with
their own overcurrent protection devices, the limit value for the protective
conductor test must be selected in accordance with the power cable
cross-section of these components, or with the overcurrent protection
devices which have been installed for them.

Insulation Resistance Test
In accordance with EN 60204/DIN VDE 0113, insulation resistance measured between the phases of all current circuits and
the protective conductor circuit with 500 V direct voltage may not
be less than 1 MΩ.
Four nominal voltage ranges are included with the PROFITEST 204+
for this test: 100 V, 250 V, 500 V and 1000 V. These can be configured as test parameters, as is also the case with the allowable
limit value for insulation resistance.
The measurement can be started in an ideal fashion with the key
(21) on the test probe (17). For capacitive devices under test, or
for DUTs with relatively long cables, press and hold the key (21 or
10) until stabilized display values have been obtained. When the
START key is pressed and held, the instrument performs
continuous, instead of an individual measurement.
Voltage at the device under test appears at the LCD in addition to
measured insulation resistance.
Discharge
Upon completion of the measurement, the device under test is
automatically discharged in order to assure absence of voltage.
The falling voltage value can be observed at the display during
discharging. The measured insulation resistance value remains in

Voltage Measurement (protection against residual voltage)
EN 60204 requires that voltages in excess of 60 V occurring at all
accessible machine components during operation must drop to a
residual voltage value of 60 V or less within a period of 5 seconds
after supply power has been switched off.
Testing for the absence of voltage is conducted with the
PROFITEST 204+ by means of a voltage measurement which measures discharge time as well. During discharge, elapsed time is
continuously displayed at the LCD after supply power has been
switched off, until the limit value of 60 V has been reached.
In addition to the type of voltage (AC, DC or AC+DC), the
respective frequency is measured and displayed as well. The
mean value is always read out.
In addition to voltage and frequency, type of voltage (AC, DC or
AC+DC) is displayed in the symbol field at the bottom right-hand
portion of the display.
If, during a voltage measurement with a measured value of more
than 60 V, the voltage value drops by more than 5% of the
measured value during one measuring period (approx. 0,7 s), time
measurement for the testing of protection against residual voltage
is started automatically. Elapsed time can be observed in the
symbol field at the display. Time measurement is stopped as soon
as the measured value drops to below the 60 V threshold.
Elapsed time required for discharge to 60 V now appears at the
display. Voltage measurement continues until maximum allowable
discharge time has elapsed (normally 5 s). The measured voltage
value is then frozen and the DATA HOLD symbol appears at the
display. If the 60 V limit is not reached within the allowable
discharge period, the voltage value measured at the end of this
period is frozen and time measurement continues until 10
seconds have elapsed. If the voltage value is still above 60 V, the
test is aborted and the instrument resumes voltage measurement.
GMC-I Messtechnik GmbH
If a value has been frozen at the display, voltage measurement is
not resumed by the instrument until:
• The START key is pressed
• The measurement is stored to memory with the i/STORE key
• Voltage measurement is restarted from the menu
• Voltage at the test probes climbs again to a value of greater
than 60 V, or, assuming the last measured voltage value was
greater than 60 V, the following measured value is even higher,
i.e. if rising voltage can be observed.
Elapsed time and the measured voltage value at the end of the
allowable discharge period are stored to memory by activating the
i/STORE key. If discharge does not occur, only the voltage value is
saved.
Note
If conductors are exposed when a machine is switched
off which are not protected against direct contact (e.g. if
plug connections are interrupted), the maximum
allowable discharge period is 1 second!

code words. These code words always start with the “@” symbol
for the purpose of identification.
@DATE
@TIME
@NAME
@SER

The following assignments apply to the type of measurement, which must be indicated in parentheses:
1: Protective conductor test
2: Insulation test
3: Leakage current test
4: Voltage measurement
5: AC high-voltage test
The measured values and the parameters from the
individual tests are printed out next to each other in a
single line in the following order.
Additional text cannot be entered to the line, i.e.
explanation or descriptions must be entered to the
report either before or after the measured values.
Protective conductor test:
1: Max. voltage drop at the protective conductor
2: Max. protective conductor resistance value
3: Test duration for protective conductor test
4: Limit value for protective conductor voltage drop
Insulation test:
1: Insulation resistance value

Any entered comment for the respective portion of the
test is read out in the same line after the code words.
@BAD ( ) “Bad” measured values only, including all of their
parameters and limit values in the same order as
indicated under @VAL.
The user must decide whether or not testing was
successful based upon this information. As is also the
case with @VAL, the parameter in parentheses indicates the type of measurement. The worst value with
reference to the limit value is always indicated, i.e. the
“bad” values are not necessarily the highest or lowest
values, but rather the worst with reference to the
respective limit values for measurements with various
limit values. @BAD can appear after @VAL, and can be
used for a simple GO/NO-GO evaluation.
Any entered comment for the respective portion of the
test is read out in the same line after the code words.
@NUM ( ) Number of stored measurements per type of
measurement. The type of measurement is indicated
in parentheses. The different types of measurement
appear in the same order as is the case with @VAL.
54
@RESULT ( ) This code adds the word “bad” to the text, if at
least one bad value has been measured for a given
type of measurement, see @VAL ( ).
@RESULT (0)
This code adds the word “bad” to the text, if at
least one bad value has been measured for a given
system.
Fully automated reports analysis is possible with the two
@RESULT place-holder code words.
6.4.2 Report Layouts
The report header, the texts which appear between the measurement series, and the footer can all be freely changed for the
creation of individualized report layouts.
Beyond this, the positions at which the measured values appear
can be determined by the user, and these can be supplemented
with the worst value, thus providing an improved overview. Time,
date, utilized test instrument etc., can also be added at any
desired position within the report.
The layout of the list which includes the measurement series is
fixed and cannot be changed.

GMC-I Messtechnik GmbH
11.7
Recalibration
The respective measuring task and the stress to which your measuring instrument is subjected affect the ageing of the components
and may result in deviations from the guaranteed accuracy.
If high measuring accuracy is required and the instrument is frequently used in field applications, combined with transport stress
and great temperature fluctuations, we recommend a relatively
short calibration interval of 1 year. If your measuring instrument is
mainly used in the laboratory and indoors without being exposed
to any major climatic or mechanical stress, a calibration interval of
2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory
(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to traceable standards are measured and documented. The
deviations determined in the process are used for correction of
the readings during subsequent application.
We are pleased to perform DAkkS or factory calibrations for you in
our calibration laboratory. Please visit our website at
www.gossenmetrawatt.com (→ Company → DAkkS Calibration
Center or → FAQs → Calibration questions and answers).

Checklist for the High-Voltage Test
Protective Measures for Personnel
➭ Switch the machine off and secure against switching back on.
➭ Perform protective conductor and insulation resistance tests.
➭ Make sure that the system is grounded.
➭ Secure the danger zone with barriers. Even narrow points of
access must be blocked.
➭ Attention in TN systems!
In these systems, the protective conductor is connected with
the neutral conductor in the terminal box. High-voltage is
therefore present between the phase conductors and the neutral conductor.
If necessary, the neutral conductor must be separated as it is
not disconnected from the mains by any fuse.
➭ Post warning signs in a clearly visible fashion.
Set Up the Test Instrument
➭ Set up warning lamps in a clearly visible fashion.
See chapter 8, “Setting Ranges for Parameters and Standard Values per DIN VDE”.
➭ Attach the emergency stop switch in a clearly visible fashion.
➭ Warn personnel working in the area of possible danger.
High-Voltage Test
➭ If the operator leaves the work area, the test instrument must
➭ Test all circuits (conductors) against the protective conductor
be switched off with the key switch, and the key must be
removed from the lock.
Protective Measures for the Machine (recommended)
➭ Review the electrical diagram and make a note of all electrical
circuits.
➭ Disconnect the neutral conductor from the mains.
➭ Short circuit all electrical circuits to themselves.
➭ Disconnect surge diverters from control current circuits, if
these would be triggered by test voltage.
➭ Disconnect PELV circuits (high-voltage testing is not required
here).
➭ Test insulation at all circuits with 1000 V. (If insulation resis-
(all switches within the system circuit must be switched on,
and testing must be performed upstream and downstream
from relays).
➭ Remove all short-circuiting after the test.
Performing the Test without Short-Circuiting
➭ Test all conductors from all circuits separately against the
protective conductor (if flashover occurs, the machine may be
damaged).
Functions Test
➭ The machine must be tested for correct functioning, especially
as regards safety functions, after high-voltage testing.
tance is OK with 1000 V, the high-voltage test should be
