MI 3152(H) EurotestXC (2,5 kV) General description
13
Test procedure
Connect test cable to the instrument.
Connect test leads to the object under test, see Figure 1.1 and Figure 1.2.
Touch test probe for at least 2 seconds.
If PE terminal is connected to phase voltage the warning message is displayed, display
is yellow coloured, instrument buzzer is activated and further measurements are
disabled in RCD tests, Rpe, Z loop, Zs rcd, Z auto, AUTO TT, AUTO TN, AUTO TN (rcd)
and Auto Sequences®.
Notes
PE test terminal is active in the RCD tests, Rpe, Z loop, Zs rcd, Z auto, Z line, ΔU,
Voltage, AUTO TT, AUTO TN, AUTO TN (rcd) measurements and Auto Sequences
only!
In case of detection of phase voltage on PE terminal in IT earthing system, the tests can
be enabled/disabled according to setting of parameter ‘Ignore PE warning (IT)’.
For correct testing of PE terminal, the key has to be touched for at least 2 seconds.
Make sure that the TEST key is grounded thorough human body resistance without any
insulated material between (gloves, shoes, insulated floors, pens, ...). PE test could
otherwise be impaired and results of a single test or Auto Sequence® can mislead. Even
detected dangerous voltage on PE test terminal cannot prevent running of a single test
or Auto Sequence®. All such behaviour is regarded as misuse. Operator of the
instrument must stop the activity immediately and eliminate the fault/connection problem
before proceeding with any activity!
