1. INTRODUCTION
Congratulations on your purchase of this test instrument which was developed to offer
realisation of all required tests and measurements on machines according to the
International Standard IEC 60204 and the European Standard EN 60204.
1.1. General description
The MachineTest 204 offers very simple operation, easy to read large LED display
which enables reliable reading of test results even in dark environment. Due to
simplicity of the instrument it is sufficient for the operator to read this short booklet to be
familiar with operation procedures.
Portable double-wall plastic housing protects the instrument against mechanical shocks,
front panel with operating elements is protected by a rough cover.
A great advantage against similar products are two uniform test leads connected to
uniform test terminals which serve for all measurement functions.
All included accessories are placed under protection cover and cannot get lost. There is
also a clear short instruction label under the cover to remind the operator anytime how
to connect test leads to tested object and what are the limit values prescribed by the EN
60204 standard.
1.2. List of measured parameters
The following parameters can be tested /measured:
Voltage drop across PE conductor / Resistance of PE conductor

MEASUREMENTS
4.3 Residual voltage
Purpose of the measurement is:
• To check if there is no hazardous voltage at mains one-phase or three-phase
plug after pulling out the plug (wall-plug connected machines).
• To check if there is no hazardous voltage at any accessible electric
component inside the tested machine after switching off the machine (wall-plug
and permanently connected machines).
Safe conditions must be assured with appropriate electric and/or mechanic construction
of tested machine. The conditions must be assured also during the machine is powered
but we must be aware that some components can become accessible only after deenergizing the machine e.g. plug pins or components behind electrically blocked
barriers.
Test of residual voltage is to be done only if there is an electric charge present
higher than 45µ
µ C, otherwise the charge may be considered as safe one.

In order to avoid inconvenient repeating of the measurement in some cases even when
measuring AC voltage, the Residual Voltage Tester offers two modes of measurement
namely:
a) Linear mode
This mode shall be used when dealing with known objects which comprise only
“linear” internal components (R,L,C). In such case simple exponential voltage
decreasing is present after switching off tested object. Such a diagram is then
mathematically scaled to maximal value of mains voltage and thus the
measurement is not required to be repeated, see the figure below.
u
diagram is automatically
scaled to max. value of
mains voltage
t
Fig. 13. Diagram of voltage decreasing in case “linear” components only
are involved
15
MEASUREMENTS
In linear mode the Residual Voltage Tester recognizes three standard mains
voltages automatically:
110 V.......................Uin = 110 V ± 10%
230 V.......................Uin = 230 V ± 10%
400 V.......................Uin = 400 V ± 10%
In order test result to be always on “safe side”, measured residual voltage is
scaled to maximal possible value i.e.:
171 Vp = 110 V × 1.1 × 1.41 .......standard mains voltage 110 V
357 Vp = 230 V × 1.1 × 1.41 .......standard mains voltage 230 V
620 Vp = 400 V × 1.1 × 1.41 .......standard mains voltage 400 V
If input voltage is out of any standard voltage ± 10%, then the tester scales
result to maximal actual value.
Example: Uin = 173 V (under standard voltage 230 V ± 10%) ⇒ result will be
scaled to 244 Vp = 173 V × 1.41
b) Non-linear mode
This mode shall be used when dealing with non-linear or unknown objects
which consist of R, L, C components and also non-linear internal components
(relays, gas lamps etc.). In this case a diagram of voltage decreasing (after
switching off tested object) may be quite unpredictable, see the figure below,
and can not be scaled to maximal voltage value.
u
relay may be
switched off
t
Fig. 14. Diagram of voltage decreasing in case of non-linear components
are involved
Disadvantage of this mode is that the measurement must be repeated several
times in order at least once tested object to be switched off at nearly max. value
of mains voltage.
In order to assure reliable result (switching off at least once at approx. max. mains
voltage) the test should be repeated at least 15 times (mathematical statistics). Final
result is positive if all partial results were positive and is negative if only one partial
result was negative.

MEASUREMENTS
Practical measurement
STEP 1
STEP 2
Prepare the tester
• Connect two test leads to the Residual Voltage Tester.
• Select appropriate measurement mode as follows:
•
Linear mode
Switch on the tester pressing the on/off key and keeping it pressed for
approx. 2s until all three red control lamps (bat, Machine Power on and
Result) go “on”, then release the on/off key. After 1s two lamps go “down”
while the bat lamp stays “on”. Residual Voltage Tester is thus in Linear
mode.
•
Non-linear mode
Switch on the tester pressing the on/off key and releasing it. Bat lamp
goes “on”, Residual Voltage Tester is thus in linear mode.
•
Select appropriate waiting time effected from switching-off moment until
taking the measurement of URES. 1s (measurement at mains plug) or 5s
(measurement inside tested machine) can be selected.
Carry out the test
• Connect test leads to tested machine, see the figure below.

Switch on (or connect mains plug to mains outlet), Machine Power ON
lamp goes “on” as soon as stable AC or DC voltage (higher than 60 V DC
or peak AC) is detected at test terminals.
•
Pull out mains plug of tested machine (measurement at plug terminals) or
switch off mains switch (measurement inside the machine) and wait for
result to be displayed (red or green control lamp). Green colour means
the level of measured residual voltage is below 60 V DC ⇒ OK while red
one means the level is above 60 V DC ⇒ not OK.
•
Valid for non-linear mode only: Repeat the measurement at least 15 times
- see explanation under “Measurement principle”. If none of test results is
above prescribed limit value (always green lamp) the machine can be
considered as to pass the test.
Write down the test result (OK or not OK).
•
•
Notes!
Linear mode only: If mains voltage is interrupted at too low value (impossible to scale
test result), then the tester requires another measurement flashing green Result lamp!
•
If already detected stable mains voltage present at test terminals (green Machine
Power on lamp lights) changes for more than 10%, then the Machine Power on lamp
starts to flash until a new stable voltage is detected!
•
Make sure always to take the first test result (displayed within 1s / 5s after mains
voltage disconnection). It might happen at extremely high capacitances (slow voltage
discharge) that the measurement will be started again automatically after completion
the first one. Then a further not valid test result could be displayed.

by 500 VA transformer is applied to test tips!
Make sure there is no third party person around the tested object
when the test is being carried out and national safety requirements
are fulfilled (e.g.: DIN VDE 0104) !
How to carry out the measurement
STEP 1
Prepare the machine to be tested
- Assure tested object to be disconnected from mains voltage.
- Switch “on” main switch of tested object as well as other switches, in
order all electronic parts of tested object to be included in the test!
- Short all live terminals of tested object (L1, L2, L3, N).
- Check electric circuit diagram of the machine or the machine itself with
regard to mains part connection. There may be some capacitors
connected between live parts (L1, L2, L3, N) and PE terminal (housing)
which serve as EMC filter or noise suppressor etc., see the figure below.
In case the capacitors are not rated for AC voltage of up to 1000 V, take
care to remove them before carrying out the test otherwise they may be
damaged. If the capacitors are rated for voltages of up to 1000 V AC then
they may remain in place if their capacitance is not too high (capacitive
current can not be compensated if the capacitance is too high), see the
next table.

6.1 Cleaning
Use soft patch, slightly moistened with soap water or alcohol to clean the surface of the
instrument or residual voltage tester. Let the testers dry totally after being cleaned
before using them.
Notes!
• Do not use liquids based on petrol or hydrocarbons!
• Do not spill cleaning liquid over the instruments!
6.2 Fuses
There are two fuses in the basic instrument.
a) General fuse (front panel): Type T6.3A / 250 V 5 × 20 mm.
The fuse may be blown if there is no display segment “on” even at
connected mains voltage and mains switch turned “on”. It may be
replaced with a new one by an operator himself. Fuse cover on front
panel (pos. 2, fig. 01) is to be unscrewed and blown fuse replaced. It is
required to use prescribed fuse only otherwise the instrument may be
damaged.
b) Auxiliary fuse (inside the instrument): Type T16A / 500 V 6.3 × 32 mm.
The fuse may be blown if “l .” is displayed in RPE / UPE function even at
short-circuited test leads. It may be replaced by authorized service
personal only. It is required to use prescribed fuse only otherwise the
instrument may be damaged. When opening the instrument it is
recommended to place it to vertical position.
Warning: All the weight (8 kg) is fixed to front panel!
The Residual Voltage Tester does not contain any fuse!
6.3 Periodic calibration
It is essential that measurement instrument (basic instrument as well as residual voltage
tester) is regularly calibrated. For occasional use, we recommend an annual calibration
to be carried out. When the instrument is used continuously every day, we recommend
a calibration interval of sixth months.

Make sure always to take the first test result (displayed within 1s / 5s after
mains voltage disconnection). It might happen at extremely high capacitances
(slow voltage discharge) that the measurement will be started again automatically
after completion the first one. Then a further not valid test result could be
displayed.
