R-ISO?
(Carry out R-ISO?) During insulation measurement, a voltage of 500 V is applied between
the active conductor and earth. Insulation testing may damage sensitive
devices. Only activate insulation measurement if permitted by the
manufacturer's instructions provided with the DUT.
Note: If the setting "Disconn. not poss." is selected, the insulation
measurement cannot be selected.
Disconnection not
possible Choose this setting if the device cannot be disconnected from the mains.
Conduct. parts >PE All accessible conductive parts are connected to PE. This setting can be
used if you know that all metal accessible parts of the enclosure are
connected to the PE conductor. During device testing, the test probe then
only has to be brought into contact with one metal point on the
enclosure.
If not all metal parts of the enclosure are connected to PE, deactivate this
function. During device testing, an additional equipment leakage current
test resp. touch current test (Class II) is carried out. In this case, the manual
test will be selected automatically.
During device testing, proceed as follows:
During PE conductor testing, use the test probe to scan all parts of the
enclosure connected to PE. During equipment leakage current testing or
touch current testing (Class II), test all parts not connected to PE.
6. Select the measurement method
for determining the leakage current,
e.g. “Direct measurement”.
7. Select other settings for the test.
Label selected setting with “ ”.
Then select menu item “5. Next”
