2 GENERAL DESCRIPTION
The instrument You purchased, if used in compliance with the indications given in this
manual, guarantees accurate and reliable measurements and the utmost safety thanks to
a development of new conception which ensures double insulation and, consequently,
compliance with the requirements of overvoltage category IV.
2.1 INSTRUMENT FEATURES
Insulation resistance measurement with nominal voltage which can be set up to 5kV
Dielectric leakage current measurement
Polarization Index (PI) measurement
Dielectric Absorption Ratio (DAR) measurement
Capacitance measurement.
AC/DC voltage measurement up to 600V
3 PREPARATION FOR USE
3.1 INITIAL INSPECTIONS
Before shipment, the instrument’s electronics and mechanics have been inspected. All
possible precautions have been taken in order for the instrument to be delivered without
damage. However, we recommend generally inspecting the instrument in order to detect
any damage suffered during transport. Should you detect any anomalies, immediately
contact the forwarding agent or the dealer. Moreover, we recommend checking that the
package contains all parts listed in § 10.4. Should you find any discrepancy, please
contact the dealer. Should it become necessary to return the instrument, please follow the
instructions reported in § 11.
3.2 POWER SUPPLY
The instrument is power-supplied through internal batteries which are recharged from the
mains by means of a battery charger integrated in the instrument itself. The symbol
“
” steadily illuminated in the right bottom part indicates that the batteries are flat and
must be recharged. To recharge the batteries, follow the instructions given in § 9.2.
CAUTION
Perform at least a complete recharging of internal battery in one year. If
the instrument is not used for one year, the battery can be damaged and could
not be completely recharging neither after some charging/discharging cycles.
3.3 STORAGE
In order to guarantee accurate measurements and protect the instrument from possible
failures, after a long storage period under extreme environmental conditions, wait for the
instrument to return to a normal condition (see § 10.3.1).
