| For the protection of humans, certain
safety precautions must be complied with when erecting
and operating electrical devices and installations.
These precautions have been laid down in national and
international regulations and must be checked at regular
intervals. All of them are ultimately based on
measurements of insulation resistance. In practice,
however, requirements differ widely; thus diverse
measuring voltages and, irrespective of these, the
largest possible ranges. In addition, a modern meter is
expected to offer useful additional measuring functions,
such as a device check after repairs and reassembly as
per VDE 0701, ÖVE HG 701 and other standards. All these
requirements must, however, not interfere with
simplicity of operation or with the overload capacity of
the instrument. The meters UNILAP ISO and UNILAP ISO X
are the perfect solution. Both instruments meet the most
stringent technical requirements within an area of
application of maximum breadth and comply with all
pertinent regulations. Their freely selectable test
voltage and outstanding high ranges, together with full
autoranging and GUARD technology, are eminently suitable
for even the toughest measuring problems, e.g. for
measuring highly insulating materials. All measuring
functions are fully automated under microprocessor
control and indicated unequivocally and for any length
of time on a large display optimized for clarity. |
