Making Capacity for the Measurement of Insulation Resistance
Electronic voltage limiting prevents voltage at the device under test from
substantially exceeding nominal voltage during the making operation (see
following characteristic curve).
8 Maintenance
Attention!
!
Completely disconnect the instrument from all external electrical
circuits before replacing the batteries or the fuse.
We recommend setting the function selector switch to the 1000 V
position during transport and maintenance, in order to prevent the
tester from being switched on inadvertently.
