Description
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, 脰VE HG 701 and other
standards. All these requirements must, however, not interfere with
simplicity of operation or with the overload capacity of the instru-
ment.
The meters
UNILAP ISO
and
UNILAP ISO X
are the perfect
solution. Both instruments meet the most stringent technical require-
ments 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.
In practice this means:
- Select function
- Press START key
- Read measured value
But UNILAP ISO and UNILAP ISO X also offer extra features:
- fully automated prompting for protection against misconnection
and damage due to misoperation
- automatic display of mains voltage before and after measurement,
and of the discharge process after measurement
- unlimited display of the results of all measurements
- simultaneous display of actual measuring voltage and insulation
resistance
- freely programmable LIMITs with optical and acoustical reporting
on high and low infringement
(standard values are stored!)
- locking of an undesirably high insulation voltage by a personal
user code
- battery-saving automatic switchoff
- condensed user instructions in user鈥檚 view
- splashproof case (IP 56)
- use of rechargeable batteries possible
- interface as option
- extensive accessories including carrying case included as supplied
- developed, designed and manufactured according to
DIN ISO 9001
