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 m
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.
