High voltage test (HV function)
• According to
EN 60204-1, electric equipment must withstand a voltage
test between shorted active conductors of power circuit and the earth
bonding system for approx. 1 s.
•
The test shall be carried out at twice the rated supply (or 1000 V
whichever is greater) 50 Hz. Components not rated for this test voltage
may be disconnected before carrying out the test.
The Machine tester MT204-S supplies high voltage of a dangerous power.
According to EN 50191 the following precautionary measures must be taken
prior to a test:
•
Block access to danger
•
Put up warning signs (Attention! High voltage, danger to life).
•
Install warning lamps (red, green) to be easily
•
Install EMERGENCY-OFF switch into the mains installation outside the
dangerous area.
•
Electrical trained personnel may only do the tests under supervision of
specialist staff and have to be trained
• Do not use crocodile clips for this test.
•
Use safety probes with two-hand operation only. Always hold only one
probe in one hand.
•
Connecting one test terminal to the object under test and working with
one probe or holding both probes in one hand is prohibited.
•
It is prohibited to touch the unit under test during the test. If need be,
additional measures must be taken (e.g. cover made of insulating mats)
to protect the person performing the test against inadvertent contact
with the test object.
Testing may commence only after all safety measures were taken.
Ensure that all switches on the unit under test are closed in order to test all
it's components. For the purpose of measurement all active conductors (L1,
L2, L3, N) shall be shorted.

1)
Release the HV measurement function by using the key switch (6)
and by turning it counter-clockwise.
2)
Set the measurement function selector (5) to "HV" position
3) Use the "It" menu key (14) and select appropriate trip current
(5...50 mA), start with the minimum value of response.
4)
Start the test by pressing the "START/STOP" button (7).
5)
Make contact with two-hand use test probes to the unit under test.
