The limit of the permissible additional measurement error caused by a change in the ambient temperature from normal (20 ± 5 ° C) to any within the working area does not exceed half the limit of the permissible basic measurement error for every 10 deg. temperature changes.
LIGHTNING-IPI-10 allows to carry out measurements according to "normal" / "direct" and "inverse" / "inverted" measurement schemes, which provides measurement of parameters of insulation of objects, both with isolated and grounded terminals.
LIGHTNING-IPI-10 provides output of measurement results on a liquid crystal display (LCD) of the indication unit. The connection between the high-voltage measuring unit and the display unit is carried out over a radio channel in the frequency range 845-945 MHz with a transmitter output power of 1 mW at a distance of 5-7 m.
The image of numbers and signs on the display is distinguishable at a distance of at least 0.8 m with an external illumination of 10 to 1000 lux.
LIGHTNING-IPI-10 in normal and working conditions of use is ready for work within no more than 1 min after switching on.
The operating time of the meter is determined by the energy consumption of the electrochemical batteries used. With a battery capacity of 1800 mAh, the operating time is at least 8 hours.
Mean time between failures for operating conditions of use is not less than 4000 hours.
The average service life of the meter is at least 8 years.
